NOTES ON SEED SOWING & CULTIVATION OF SEEDLINGS
All seeds must have adequate moisture, air and heat before they will germinate. The seed compost should
therefore have a high fibre (peat) content to ensure both good water retention and reasonable aeration.
All seed should be sown thinly, and seedlings should be given as much light as possible. In some cases
(e.g. Alstroemeria) a few seeds may germinate quickly but the rest will germinate a few at a time over a
period of months.
CLASS 1 The Anthemis, Lavatera, Clematis tangutica, Rhodochiton, Eccremocarpus, Alstroemeria, Pulsatilla
and Fennel are very easy to raise from seed. Sow thinly and cover with 2-3mm layer of sifted compost
CLASS 2 The Primula and Meconopsis species require slightly more care as the seeds are small and the
young seedlings are delicate. A peaty compost (e.g. Equal parts of seed J.I. and peat) is best. The larger
seeded species (P. Florindae, P. Japonica) may be very lightly covered, but the other species should be
sown on the level surface of the compost. The surface must therefore be kept moist at all times. A rough
peaty surface is important so that seedlings’ roots can easily penetrate the compost.
CLASS 3 Rhododendron (including Azalea), Pieris, Gaultheria and other ericaceous seed is very small and
should be sown on the surface of peat, or a mixture of about 10 parts peat to 1 part J.I. Compost.
CLASS 4 The Astrantia, Angelica, Hosta, Gentiana, Sorbus, most Acer, and Clematis rehderiana seed
requires a cold (and moist) treatment (stratification) before it will germinate. It may be sown in autumn
(October/November) in pots and left outside until germination occurs in the spring. If pots are covered to
protect them from mice, birds, etc., care must be taken that the soil does not dry out. Alternatively seed
may be kept for about 90 days (3 months) in a domestic refrigerator (optimum temperature 1° - 5°C) on
moist paper towelling in a covered dish. During this time the seed must not be allowed to dry out. After
the cold treatment the seed is sown as Class 1. Some seed may germinate (even at 1°C) in the refrigerator
within the 3 month period. The germinated seeds should be pricked out as soon as the elongated radical
(little root) can be seen protruding from the seed, and the dish with remaining ungerminated seeds
returned to the fridge immediately. With Astrantia and Sorbus, if the seed is kept permanently in the
fridge and not sown after
3 months, a much higher percentage of germination can be achieved—though some seeds may not
germinate until their third spring after 3 years in the fridge. Fungal growth may be ignored or the seeds
may be cleaned and put on clean paper.
CLASS 5 Paeonia, Lilium, Fraxinus (Ash) and most Acer griseum, A. palmatum, A. japonicum and A.
nikoense seed require 2 cold periods (winters) before they will germinate (e.g. If sown in autumn/winter
2013 they will germinate in spring 2015).
SOWING TIME
Perennial species may be sown at any time so long as they can be kept growing for 3-4 months (remember
to allow up to 6 weeks for germination) before becoming dormant. Sowing is best therefore done in
spring, and autumn is best avoided (except, of course, for species requiring stratification) unless adequate
light and heat can be provided to sustain growth over the winter
GROWING ON
Once the seedlings are crowded and large enough to handle (which depends on how thickly the seed was
sown and how delicately you can manipulate the seedlings) they should be pricked out into individual pots
in compost similar to the seed compost to grow to a reasonable size before planting out in the garden.
Rhododendrons in pots should be grown in compost that is at least three-quarters peat. If sown in the
spring Primula frondosa will flower later the same growing season. The other species of Primula,
Meconopsis, Clematis, Anthemis, Fennel, Astrantia and Angelica will flower in the following season.
Rhodochiton atrosanguineum and Maurandia spp. are usually treated as half-hardy annual climbers

Not all plants from seed come true. The meconopsis
grandis shown right grown from seed at Ness has,
instead of a single blue flower, double petals with some
cream and purple markings.
Meconopsis grandis
Some seeds on the list have a collectors code that
connects the plant back to where it originated in the
wild. In the photo left the F stands for Gerorge
Forrest followed by the code number which links to
records that show where the plant was collected;
in this example, Yunan Province, China.
