For quite references, H. serrata and presumed hybrids (H. x preziosa) are coded with red font text. Macrocephala (H. hortensis macrocephala hort. ex Beiss, Schelle, Zabel, Hand. Laub.-Benen. 132 1903) - Hortensia, apparently of very large heads, listed apart from 'Macrosepala'. This epithet translates to "large head". Macrophylla (Viburnum macrophyllum Thunberg, Fl. Jap. 125 (1784), H. macrophylla C, Prod. 15 (1830), H. hortensia var. macrophylla hort. ex Beiss, Schelle, Zabel, Hand. Laub.-Benen. 133 1903, with H. chinensis hort. and H. sinensis hort. as synonyms) = H. macrophylla, not a specific clone. Macrosepala (serrata)(H. japonica macrosepala Regel in Gartenflora 1866) - large, toothed sepals, blush to near white. Three sepals may occur as well as the normal four per floret. Traditionally, it differs mainly in larger, more toothed sterile sepals. This entity is close to 'Rosalba' and could be 'Beni-gaku' aka 'Benikaku', one of the original imported clones. Wilson in JAA considered it a whiter version of H.m. var. normalis f. azisai Wilson, naming it f. macrosepala with the pinker form being called var. normalis f. rosea Wilson. Robinson in The English Flower Garden (1900) said "it is exactly like acuminata [our H. serrata f. acuminata which is close to f. serrata today], save that the flowers are tinged with red, and the sepals of the barren flowers [steriles] are elegantly toothed". From Regal in Gartenflora 1866, courtesy of Google Translate: The previous form very close to the leaves of the sterile flowers are wide but up to l '/ • inches. A beautiful carmine-pink coloring of the same Sets, likewise later in the culture one in free air. This new form is introduced by our Maximowicz Figure dar. Dippel's Handbuch of 1893 is clear on 'Macrosepala' too and with more detail as was his style. This courtesy of Google Translate: ● f. macrosepala, bloody big hydrangea. (Japan Hydr. Macrosepala Rgl. ô •. •. •. •. 5••. Hydr Hortensia japonica Maxim ß, •. •. O. Hydr. Sieboldi hear.) Leaves ovate, up eilänglich eilanzettförmig, slightly narrowed at the base or rounded, acute to acuminate, coarsely serrate, 8-12 cm long, 4-6 cm wide, and 8. Blooms in shallow to Uber i5cm wide slip with very large clusters, 3-4 cm long and almost as wide, white, pink at the top, later the same fertile BiUten, carmine-pink to carmine petals coloring the barren flowers. I was delighted to find this nursery listing from Catalog von Gewachschaus-pflanzen der H. Laurentius vol. 40 of 1868, showing they had two foliar variegates then, one likely the old 'Maculata' (aka elegans maculata) and the other close to 'Argenteo-variegata' of other literature. This is not to say that nurseryman cannot offer the same clone under two names, not yet knowing due to slight phenotypic differences of plants from two sources, but this is not likely with this mature firm. Maculata (Variegata in part, 'Mariesii Variegata' in part, H. hortensis var. maculata Blume, Bijdr. 920 (1826), H. japonica fol. albo-variegatis van Houtte, Fl. des Serr. 139 (1851-2), H. japonica variegata K. Koch, Hort. Dend. 106 (1853), H. hortensis variegata Nich., Dict. Gard. 163 (1887), H. hortensis fol. elegans maculata hort.) - margined white. Note this plant is much older than 'Mariesii', suggesting many to conclude it cannot be 'Mariesii Variegata'. There is no clear evidence that 'Mariesii Variegata' sported from 'Mariesii', so I suspect it was just considered a variegated plant like 'Mariesii'. 'Mariesii'-like plant certainly existed in 1826 so a sport of such material could easily have become associated with the later clone. 'Madame Emile Mouillere', as pretty a pale pink Hortensia as could be asked for, not to be bold and excessive, just right to my eye. Many plants are not as pink as this example. Madame Emile Mouillere (Mouillere hort., the name sometimes shortened in catalogs in various versions incl. Mme. E. Mouillere, M.E. Mouillere) - white, blushed pink if given some sun, often grown as nearly pure white, sometimes with a blue or pink center if pH permits Hortensia, sepals nicely frilled or serrate, Long bloom. Considered by some to be the best blush-white in the Hortensia group. RHS AM 1910. Or: Mouillere, France c. 1909, offered more widely in Holland c. 1932. Mme. Auguste Nonin - light or pale pink, Hortensia. Upright. Palish green leaf. Mme. Faustin Travoullion (Peacock) - steriles reddish-rose to medium blue, Hortensia, floriferous. MAGICAL SERIES - offered by Kolster Beheer B.V., Holland, bred by Cornelius Pieter Eveleens, Netherlands. While some of these show US Patents as cultivars, they are widely listed as trademarks, registered and not. These clones must be declared either a cultivar or trademark entity with these epithets for they cannot be both at once. Use of registered and unregistered trademarks varies widely in catalogs and literature. ● ● ● ● MAGICAL AMETHYST, EVERLATING AMETHYST 'Hokomathyst' - Hortensia, mostly green at first, later with wide reniform to obicular sepals, very prominently ridged and serrate, centered bright pink to cerise-rose mixed with medium to light green, I for one see no amethyst colors in plants and photos known to me, marketed as "lime green and fuchsia" MAGICAL BRILLIANT - Hortensia, steriles much cupped/concave, undulate mix of cream, green, and pink shades at first. MAGICAL CORAL - Hortensia, steriles distinctly textured and ribbed, rich coral-pink to medium pink, accented by rich emerald green centers, margins, and oddly shaped zones, some interrupted by cream to near white lines. MAGICAL CRYSTAL/MAGICAL CHRISTAL - Hortensia, steriles generally few but large, not densely ● ● ● ● ● ● ● ● ● ● packed in general, mostly broadly suborbicular to reniform, entire margins but also leisurely undulate, light greenish-cream tinged pink on the margins in a subtle pattern, maturing to either a pale boue to medium pink. MAGICAL DANIQUE - Hortensia, fertiles few but large, mid-light pink, distinctly serrate but aso entire, sepals broadly suborbicular to orbicular, not as dense as traditonal cultivars of this color but also more simple and natural-looking in it's charms. MAGICAL DIAMOND - Hortenia, fertiles a subtle mix of pale minty green shades and blush to light pinks, somewhat a muddled look to me but as mix of pastel shades it is somewhat unique. MAGICAL EMERALD - "very light pink". Plants mounded, upright. MAGICAL GARNET = Hortensia, steriles bright candy pink, sepals very broadly ovate, obtuse, much greener in bud. MAGICAL HARMONY - Hortensia, steriles light pink with distinct green centers, sepals as open cups, broadly concave, not much crowded nor undulate. MAGICAL JADE - Hortensia, steriles cream tinged lime to light greeen, rarely dark emerald sahdes as MAGICAL WINGS, distinctly serrate to subdentate, opening whiter with barely any green near the margins, adding with hot pink to magenta edges. MAGICAL JEWEL - Hortensia, steriles ribbed and textured, very rich emerald green with dark carmine-red marginal tints, a very lovely mix of highly pigmented green and near red shades. MAGICAL MOONLIGHT = H. paniculata cv. MAGICAL MOONSTONE - Hortensia, steriles few but large, broadly concave and slightly undulate, mix of light to mid-pink shades, centers a paler pink, these centers more green in bud, sepals broadly triangular. MAGICAL NOBLESSE - Hortensia, steriles cream to white in the center, the small central eye lavender-purple, margins and apices bright lime to medium green with paler to cream veins, green to white ratio variable at 20:80 to 50:50, far more white than most white- or cream-centered cultivars in the trade, the cream portions sometimes a wash or fade in older more green florets, these sepals richly veins and textured (subrugose to incurled and subrevolute with more age), old florets almost like a mint leaf with a white flush, strongly serrate along most of the margins. Image follows. There is nothing else like this on planet (August 2011). ● ● ● ● MAGICAL OCEAN 'Hortmoc' - Hortensia, steriles white, serrate, undulate, tinged very rich green at first, very center eye a rich violet-red to pink, sepals both serrate and sometimes long-acute, the crowded sepals funnelform-concave with darker centers at maturity, the serrations remaining strong. MAGICAL OPAL - Hortensia, steriles serrate, medium to dark pink, large dense heads. Plants mounded, upright. Also grown as a mix of light blue and lavender shades, very pretty in this bluer phase. MAGICAL PEARL 'Napo' (8/11) - steriles greenish-cream in small bud, near white at maturity, broadly triangular-ornicular, apex often distinct as acute to narrow obtuse-acute, a fairly triangular ● ● ● ● ● ● shape overall, florets mostly flat, only a bit concave, generally not much folded or undulate, long duration as cut flower. Leaves dark green. MAGICAL ROBIN 'Horo' (8/11) - Hortensia, steriles broadly ovate to reniform, almost all obtuse, orangish-rose to coral-pink veined paler shades, some vermilion and pale coral-rose tinged green seen at times, extreme eye rich green. Overall a good blend of red, coral, and green shades, much folded and dense. MAGICAL RUBY - steriles irregularly serrate, at first greenish in center, later rich ruby red shades on the margins. MAGICAL SAPPHIRE = Hortensia, steriles rich blue or strong carmine-pink, centers more green in early stages, later more medium to hot pink with reddish marginal tints. MAGICAL TOPAZ 'Rambo' - Hortensia, steriles very wide, distinctly serrate and serrulate, narowly concave or cupped as florets, medium to pale green in bud, maturing to light-mid pink, a clean candy or bubblegum shade to my eyes, the sepals remaining irregular and toothed in their outlines. The sepals are slightly clawed, showing a small gap at their bases resembling a reddish or dark cross. Esveld offers as lovely set of shots: http://www.esveld.nl/htmldiaen/h/hymram.htm MAGICAL VERONIQUE - Hortensia, steriles light pink, slightly paler on the margins, irregularly undulate and entire to subserrate. MAGICAL WINGS - Hortensia, steriles irregularly serrulate, serrate, and undulate, an irregular mix of dark emerald green, lime, andwhite shades, some sepals mostly green, others mostly white, some centered white only but generally irregular in this color distribution. Maiko (serrata) - steriles mauve, fertiles lavender-purple, very floriferous, intermediate between Lacecap and Hortensia (ie. fertiles very few), heads subglobose and loosely formed. 3 ft. tall x wide, shorter than most clones of the species. Marathon (7/11) - bright red, globose heads. 1.5m tall, compact. Showy red to dark red foliage in fall. Or: K. Wezelenburg, Holland c. 1967. Marechal Foch - grown both as fertiles bright blue or rose-pink, has purple tints in acid Hortensia, slight open with spreading sepals, early season. From Emile Mouillere. RHS AM 1923. One of our better oldish plates of 'Mariesii', this showing clearly triangular-rhombic sepals (Catheranthus-like). This plate is from Robert Thompson and William Watson's THE GARDENER'S ASSISTANT 2: 304 of 1900 where 'Mariesii' is descirbed as "remarkable for the large size of it's pink barren flowers, which are 3 inches across"\ \ This description comes The Gardeners of January 1881 and thus reflects an early view of it. Mariesii - steriles light blue or lavender-blue if acidic (mauve-pink if neutral), apparently grown pink in early years (see plate above), Lacecap, the sterile and fertile flowers are oddly scattered unlike most modern clones 4-5 ft. Narrower leaf than most cultivars. A classic but 'Mariesii Perfecta' aka 'Blue Wave' is replacing it. RHS FCC 1881, AGM 1938. Charles Maries (for whom it is named) imported it from Japan in 1879. Robert Hogg in The Florist and Pomologist (1881) reports on this clone: One of the most interesting of Japanese shrubs is the Hydrangea Mariesii, recently exhibited by Messrs. Veitch, and certificated by the R.H.S. It is a distinct-looking plant, of freegrowing habit, with grayish-green cordate-ovate deeply-toothed leaves, and large terminal roundish close-set cymes of lavender-blue sterile flowers, quite different in aspect from the blue form of Hydrangea Hortensia. The plant was introduced three years since by Mr. Maries, to Messrs. Veitchs' collection, but was on this occasion exhibited for the first time. Mariesii Alba = Mariesii Grandiflora "M.H." in "Neu Hydrangea Mariesii-Varieten" Gartenwelt vol 9: 414 (1905) gives us the oldest photo known for the whiter, 'Mariesii Grandiflora'. A second plate form this article is shown below. Mariesii Grandiflora (Mariesii Alba, White Wave) - steriles very large, pearl white, broadly ovate to suborbicular, obtuse to acute, very often quite acute, some stock more obtuse (perhaps indicating polyclonality), fertiles fainted tinged blue to pink, often creamy in the center, hence a mostly whitish flower in this phase, flat Lacecap. Leaves ovate, glossy green. Habit 5 ft., compact. RHS AM 1948, AGM 1993 awarded as 'White Wave'. "M.H." in "Neu Hydrangea Mariesii-Varieten" Gartenwelt vol 9: 414 (1905) gives us the oldest photo known for this clone. I'd translate and dig very deep into this article to find out even more about these clones. Maries Lilacina (Lilacina) - as 'Mariesii' but more lilac tones in the center. Based on the plate shown above the sterile sepals appear to be more serrate. Leaves from the above photo seem to be very deeply serrate-dentate, more than normal. RHS AGM 1999, awarded as 'Lilacina' "M.H." in "Neu Hydrangea Mariesii-Varieten" Gartenwelt vol 9: 414 (1905) gives us the oldest photo known for this clone. I would consider these sepals far more orbicular (rounded) and serrate than the original 'Mariesii'. Mariesii Perfecta (Blue Wave) - steriles rich blue (lilac to pink if neutral), fading lilac to pink at margins with maturity, if the above plate from Gartenwelt is true, this clone appears to have wider orbicular to reniform fertile sepals with added serrations, fertiles also blue to pinkish, Lacecap, symmetrical heads. Leaves glossy, light green. 6 ft., vigorous. Older plants can develop a nice horizontal look something like a Viburnum plicatum in flower. Undulate sepals give a nice wavy look. The best plants seem to be those with a bit of shade. Selected from 'Mariesii' by Lemoine c. 1900 and replaces it. RHS AM 1956, FCC 1965, AGM 1993. It was named so long ago that the Latin version of the name must be accepted as valid. The RHS use it while Dirr prefers 'Blue Wave' 'Maculata'? Flowers are quite optional with a leaf this good, better than a similarly shaped Cornus shrub in fact; dark and rich green shades with pristine, pure white edges of variable but steady dimensions. New margins are a bit cream to light yellow, suggesting to some that these plants may be 'Tricolor'. Mariesii Variegata some=Maculata - light blue if very acidic (mauve-pink if neutral) - 4-5 ft. Wide but irregular white margins in one clone/chimeral phase at least (see photo above). A great cultivar for many seasons of beauty. It will bloom on older plants. Some plants under this name have very thin, even incomplete white margins so as with many variegated plants, the chimera varies with time and place. One cannot say the wider-margined plants are one name or another today and the narrow ones another for both are called 'Variegata' and 'Mariesii Variegata' in my experience. One need only purchase the stock the pleases you and meets your specific expectations whether wide, medium, or thinnly edged. Some firms like Monrovia (online catalog 2011) offer 'Mariesii Variegata' with a very thin often incomplete white edge while their 'Variegata' is a stronger, broader edge, both flowers very much in line with 'Mariesii' as it turns out. Maries dates from 1880 while 'Maculata' is much older in 1826, more widely known in 1850 or so. I suspect it is not a sport of 'Mariesii' but a variegated sport of a lacecap very much like 'Mariesii' and therefore assigned as a partner to it much later on. See under 'Variegata' below for an old plate. Masja (Sybilla, Sibilla) - fertiles near red as preferred, can be made rich bluish-purple, Hortensia, large head. Habit semi-dwarf. Improved glossy leaf but cold hardiness is an issue everywhere. Mathilda Gutges - sterile sepals rich violet-blue, sometimes grown with a bit of pink or lavender in it, it is possible for heads of very diverse blue and pink colors on the same plant (when young), Hortensia, mid to late season. A nice plant to experiment to pH. Getting two flower colors or several on one plant is a nice science experiment and will amaze children and neighbors. var. megacarpa Ohwi (subsp. yezoensis (Koiz.) Kitamura (serrata) - literally, this name means "largefruited". Searching modern Japanese websites this name is used for a Lacecap, steriles few, 3-4 sepals, medium blue, rhombic-ovoid, fertiles medium blue and numerous. Merritt's Beauty - steriles carmine-red, Hortensia, globose head. Compact, sometimes slow to establish. Merritt's Pink - pink, Hortensia. Probably is 'Merritt's Supreme' also known as 'Merrit's Supreme Pink' Merritt's Pride - Hortensia. 'Merritt's Supreme', a bright candy pink with a bit of magenta more than often. Merritt's Supreme (Merritt Supreme Pink?) - carmine red to reddish-pink, Hortensia, very large, serrate sepals add interest, early to mid-season. One of the best modern reds. Merritt White (8/11) - sepals white, Hortensia, aging to green shades but resistant to sunscorch, not turning brown, heads long-lasting. Compact habit. Or: US Patent# 21668 on Jan. 25, 2011 to Harrison Higaiki, San Mateo, CA, found in a field of 'Ravel'. Merveille = sterile sepals light pink, Hortensia, early to mid-season. MIDNIGHT DUCHESS® 'HYMMADII' (10/6, amended 7/11 as registered trademark) - sterile flowers light mauve-purple, effectively light pink from a distinct, fertile light whitish-lavender to lavender, not much affected by pH, Lacecap. 3-5 ft. tall, showy blackish-purple stems, strong stems to hold head weight, glossy dark green leaf. Very mildew resistant. Unlke parent 'Nigra' it is more heat and drought tolerant. Or: Dr. Mike Dirr. Sold by McCorkle Nurseries under the ROYAL MAJESTICS™ series.

Miss Hepburn - steriles pink to dark purple, Hortensia 'Miyama-yae-murasaki' above the Asian Valley (near the main road), US National Arboretum, Summer 2005 Miyama-yae-murasaki (serrata)('Purple Tiers') - steriles mauve to violet-pink, even violet-magenta, not a true purple or clean violet in general, outer whorl or sepals much enlarged compared to central, inner ones, almost giving the look of a tiered, semi-double flower. Leaves bright green, more visibly serrate than some clones of this species. Or: Takeshi Seto found near Miyama, near Kyoto, Japan 1950 f. prolifera 'Miyama-yae-murasaki' ('Purple Tiers') click image Mme. Emile Mouillere white, often with pink or bluish eyes, Hortensia, 6-8 in. heads. 4-6 ft. Early but very long bloom period. The huge refined blooms make it s true classic.

RHS AM 1968. Nickanyana (macrophylla var. normalis) - listed name, Raulston Arboretum. This synonomy in Beissner, Schelle, and Zabel (Hand. Laub-Benin. 1903) shows the convergence of black, red, and cyanoclada types as one entity. 'Nigra' at the US National Arboretum in the Asian plant garden collection near the Bonsai Pavillion. The flowers here are small and pretty mediocre but those stems in winter are shocking and lovely. The modern red-stemmed clones like LADY IN RED are apparently derived from the dark pigments of this taxon. It's not clear when 'Nigra' or the dark-stemmed clones came to North America but this reference in the Transactions of the Mass. Hort. Soc. of 1896 is at least a starting point for our historical study. To get the rest of this file...
