Spring Standouts

by Marie Hofer, Gardening editor, HGTV.com

Think of spring shrubs and the usual stalwarts — azaleas, white viburnums and spireas — come to mind. If you're searching for something a little different, however, these shrubs have plenty to offer.

Have one of these beautiful shrubs in your garden, and you're bound to have visitors asking you what it is. Viburnum plicatum 'Kern's Pink' (also called 'Roseace' and 'Pink Sensation') offers a mix of pink and white flower clusters — plus, a mix of green and rosy-bronzed-tinged foliage — all on the same plant. This broad-spreading shrub, usually a globular form 6 to 10 feet high and wide, is hardy in USDA Zones 5 to 7(8).

After the white, very profuse spring flowers fade, this dense twiggy shrub (the first of the spireas to bloom) becomes clothed in very narrow, yellowish-green leaves, a snappy fine-textured contrast to other spireas. The foliage turns a dull coppery orange in autumn, then drops.

Habit is a spreading mound, tightly packed with artfully arched branching. Pink forms are also available.

The rugged and hardy Thunberg spirea tolerates almost any type of soil but prefers a well-drained acid soil. Give it part to full sun, and prune after flowering to keep it from becoming leggy and open. Mature height: 3 to 5 feet tall and wide but can grow larger. Zones 4 to 8.

Sweetbox (Sarcococca hookeriana)

Sweetbox proves its worth with heady early-spring fragrance, not showy flowers (the tiny but aromatic flowers, tucked in the joints between leaf and stem, are hidden by the foliage) and with lustrous, narrow evergreen foliage. But you might appreciate even more this plant's ability to cover ground in shady areas. Spreading via rhizomes, a few sweetbox will knit together and form a dense, finely textured small hedge. Easily controlled and not invasive, sweetbox (also called sarcococca) is particularly useful wherever you want a troublefree but interesting groundcover that also perfumes the garden. S. ruscifolia (fragrant sweetbox) has red fruits, but you have to part the leaves to see them. S. orientalis flowers in the dead of winter.

Sweetbox needs partial to full shade and moist, well-drained soils, preferably acid.

Mature size: 4 to 6 feet high and wide for the species, but what often appears in nurseries is S. hookeriana var. humilis, which grows no more than 2 feet high. S. orientalis climbs to 2-4 feet; S. ruscifolia, 3 feet. Zones 6 to 8 for most sarcococcas, except S. ruscifolia (Zones 7 to 9). S. hookeriana can be pushed to Zone 5 with protection.
