sun to partial shade in moist, well-drained soil.
Spiraea cantoniensis, or Reeves’ Spirea, is a fast-growing, drought tolerant shrub that
does extremely well in our area. This shrub typically reaches 3 to 6 feet. tall with wiry, arching
stems. The leaves boast a dark green color on top and a pale blue-green beneath. Without pruning, S. cantoniensis will form a lovely mound of gracefully arching stems which, in midspring,
become heavy with masses of pure white flowers. The cultivar ‘Lanceata’ boasts double flower
blooms, making this selection the most popular selection of the species.

Spiraea japonica ‘Golden Princess’
Spiraea japonica, or Japanese Spirea, is perhaps the most wellknown of the Spireas. This species boasts the widest variety of forms
and colors available on the market today. Similar in habit to Spiraea x
bumalda, Japanese Spirea typically reaches 2 to 4 feet tall with foliage of
various colors, depending on cultivar. The foliage can range in color from
chartreuse to bronze to blue-green, depending on the variety. Flat-topped,
pink flower clusters are displayed in spring. The cultivar ‘Goldmound’ ‘has
rich golden yellow foliage that holds its color in the heat. ‘Limemound’
and ‘Golden Princess’ are popular cultivars with golden foliage. ‘Shibori’
may be the best of the Japanese Spireas. It offers deep rose, pink, and
white flowers on the same plant. It is a vigorous, rounded cultivar that
grows 3 to 4 feet tall.
Spiraea prunifolia is commonly known as Bridalwreath Spirea
because of its lovely masses of snow white flowers borne in early spring.
It is an upright, clumping, deciduous shrub with arching branches. It
typically reaches heights around 4 to 8 feet tall with a similar spread.
Although it can become somewhat leggy over time, this is an attractive
old-fashioned shrub that is considered to be an heirloom plant here in the
South. Its profuse bloom period begins prior to the emergence of foliage,
which is a shiny dark green color. In fall, this color develops into a spectacular orange-gold. S. prunifolia ‘Plena’ is a long-time favorite, known
for its double clusters of white flowers and yellow-orange fall foliage.
Spiraea x vanhouttei, or Vanhoutte Spirea, is another deciduous
hybrid that can reach 6 to 8 feet tall. This shrub is actually a hybrid cross
Spiraea prunifolia ‘Plena’
between S. trilobata and S. cantoniensis. It is best known for its showy
spring bloom period, when tiny white flowers cover the shrub, causing its branches to arch down gracefully. Its leaves,
which are serrated and a dark blue-green color, have been known to turn an attractive purple color in the fall. This is an
excellent flowering specimen, and as such should be planted as an accent shrub in the garden. It also makes a lovely hedge
or as part of a border.
