Spring flowering shrubs (and trees) are the first things you
should plant in your garden. They are the permanent foundation of your garden and will form the main structure and framework. The beauty of shrubs is that they grow and develop to blooming size fairly quickly, so you will be able to enjoy them that much sooner, and you will enjoy watching your carefully planned garden grow from a barren site with potential to a personal paradise in a few short years . If you are starting from scratch, you have the opportunity to include spring flowering shrubs to delight you from the end of winter until the onset of summer. If you are revitalizing an existing garden, decide where you need to add color, a screen, or just something new to enjoy in the springtime. So choose your favorites, or have fun learning about some new ones!
Things to Consider When Planning Your Spring Flowering Shrubs
Abeliophyllum distichum, Korean abelialeaf, Zones 5-8. This white flowering shrub is often mistaken for a white blooming forsythia, and often blooms along with it from late winter into early spring depending on location.
Aesculus pavia, red buckeye, Zones 6-9. Handsome in bloom with its large panicles of pinkish-red tubular flowers produced at the ends of the branches, this native shrub or small tree is eye-catching in spring. Plant it in full sun for best flower production, but give it sufficient room for it can reach 10 to 20' high with greater spread. Hummingbird attractant.
Azaleas are included in the genus Rhododendron. There are
evergreen and deciduous ones, and so many different hybrids and cultivars have been developed that the only thing to do is to visit local nurseries and gardens in your area to see them in bloom in order to choose your favorites. Shown below in order: 'Coral Bells,' a Kurume hybrid, 'Judge Solomon,' an "Imperial Family" hybrid from Monrovia, and 'Koromo Shikibu' with spidery lavender petals.
Calycanthus floridus, sweetshrub, Zones 4-9. This spring-
flowering shrub is known by many names--sweetshrub, Carolina allspice and spicebush to name a few--but whatever you call it, it has a delightful fragrance and charming multi-petaled flowers in a deep maroon red. A couple of good red cultivars are 'Edith Wilder' and 'Michael Lindsay.' There is also a yellow-flowered variety called 'Athens.' Mysteriously, not all sweetshrubs are fragrant. To ensure you get a fragrant one, it's best to experience one in flower at the nursery. Native to the southeastern U.S.
Calycanthus raulstonii 'Hartlage Wine,' hybrid sweetshrub, Zones 7-8. This shrub is an intergenetic cross between our native Calycanthus floridus, sweetshrub and Sinocalycanthus chinensis, or Chinese wax plant, combining the best traits of both parents--the deep red of C. floridus, softened to a rich rosy wine, and the larger blooms, broader petals and larger leaves of C. chinensis--to a gorgeous effect. Unfortunately, it's not fragrant, but that is a small negative given the lovely flowers.
Camellia japonica, Japanese camellia, Zones 7-9. Camellia
japonicas span the season from late winter into spring. They are
among the most beautiful of spring flowering shrubs, but do best in the warmest zones of the country. Some hybrids, such as 'Governor Mouton' are more cold hardy than others. Check your local nursery for specific varieties for your area. There are too many beautiful cultivars to name, but click here for a few choice ones. 'Carter's Sunburst' is shown below.
Corylopsis glabrescens, fragrant winterhazel, Zones 5-8.
Pendulous clusters of yellow flowers appear in March on a large
shrub that can reach 15.' This species is considered the hardiest.
Corylopsis pauciflora, buttercup winterhazel, Zones 6-8. Of all the winterhazels, this one is the most delicate in appearance, and its smaller size (about 6') fits in well in limited spaces. The small, pale yellow fragrant flowers are charming.
Corylopsis sinensis var. sinensis, Willmott winterhazel, Zones 6-
7. This is a beautiful shrub with slightly greenish, long clusters of fragrant pale flowers with red-tipped anthers which open from large brown buds that resemble hazelnuts. Any of the winterhazels would make a lovely addition to the early spring shrub border or as a hedge or specimen. I like the pale yellow of the winterhazels vs. the stronger yellow-gold of forsythia, for instance, but they both have their uses.
Corylus avellana 'Contorta,' Harry Lauder's Walking Stick, Zones
4-8. This is a great fun shrub to grow because of the curiously
twisting and corkscrewing branches (great for flower
arrangements). Long pendulous yellow catkins (also twisted)
emerge in March and last a long time.
Cotinus coggygria, smokebush, Zones 5-8. A shrub or small tree, smokebush is one of the most unusual plants in bloom with the effect of clouds of smoke among the leaves. The actual flowers are small and insignificant, but they produce fine hair-like filaments that create the smoky effect. There are green and purple-leaved forms. The cultivar, 'Grace,' a purple-leaved one, is pictured at the Atlanta Botanical Garden. Other popular cultivars are 'Daydream,' a green-leaved one; and 'Royal Purple,' self-explanatory.
Daphne cneorum, rose daphne, Zones 4-7. This low evergreen shrub makes a lovely ground cover and is smothered in fragrant pink or white flowers in spring. It is somewhat fussy as to conditions and prefers part shade, moist, well-drained humusy soil and cooler temperatures--so best for the northeast.
Daphne x burkwoodii, Burkwood daphne, Zones 4-6. One of the
loveliest of the spring flowering shrubs is 'Carol Mackie,' a
Burkwood clone with variegated foliage and fragrant flowers that are pale pink in bud and open to white. Like many daphnes, however, these tend to be short-lived.
Daphne genkwa, lilac daphne, Zones 5-7. I was visiting the Smith
-Gilbert Gardens in Kennesaw, Georgia and came across this daphne in full bloom. Gorgeous color, but lacks the fragrance of other daphne species. Still this deciduous species from China is a spectacular spring flowering shrub.
Deutzia rubens, white deutzia, Zones 6-8. I was very impressed
with this shrub when I saw it in full bloom at the J. C. Raulston
Arboretum in Raleigh, N.C. in late April. It was literally
smothered in white double bell-shaped pure white flowers dripping from the tips of the branches. Fallen petals covered the ground like snow.
Deutzia scabra, fuzzy deutzia, Zones 5-8. This is an old-fashioned shrub that is not in vogue, but perhaps it should be. It is a good choice for a shady border, and it blooms itself silly smothering itself with pure white fringe-y flowers. Quite lovely, really.
Enkianthus campanulatus, redvein enkianthus, Zones 5-7. Clusters of creamy bell-shaped flowers veined with red (hence the name) form at the tips of the branches. Enjoys the same soil and growing conditions as rhododendrons. Best in the cooler climates of the northeast and the Pacific northwest.
Exochorda racemosa, common pearlbush, Zones 4-8. Lovely as a bride! Round buds resemble pearls and swell like little
balloonflowers opening to showy five-petaled pure white flowers.
Curious five-lobed seedpods in the fall resemble star anise.
