Slender deutzia is an attractive deciduous shrub with a long history as a garden favorite. Deutzia grows erectly to 6 ft (1.8 m) high but assumes a mounded form with age and is usually seen at 2-4 ft (0.6-1.2 m) with an equal spread. The shrub's slender stems are yellowish green-brown and hold opposite, lance to oval-shaped leaves that are 2.5-3 in (6.4-7.6 cm) long and 0.75-1.5 in (1.9-3.8 cm) wide. These are smooth, thin and delicate with a bright green upper surface and smooth, almost white undersides. For about two weeks in April or May these shrubs completely cover themselves with racemes of pure white, cup-shaped flowers 0.5-0.75 in (1.3- 1.9 cm). The pure white flowers against the handsome green foliage gives the shrub a particularly appealing fresh look that catches the eye and sensitive noses will enjoy the plants light fragance.
