The Story

Plant Bio

Hibiscus syriacus, or Rose of Sharon, is a vigorous, upright, vase-shaped deciduous shrub valued for its large, tropical-looking flowers that provide a long bloom season in late summer.

'Blueberry Smoothie' is part of the Smoothie series, featuring fluffy, fully double flowers in a rich lavender-blue color. It blooms prolifically from mid-summer until frost.

Uses & Benefits:

'Blueberry Smoothie' provides a fantastic display of color in the landscape from mid-summer to fall, a time when many other shrubs have finished blooming. The large, fluffy, lavender-blue flowers have a tropical feel and are a welcome sight in the late-season garden.

It can be grown as a standalone specimen, grouped to form a dense hedge or privacy screen, or even trained into a small tree-form standard. Its tolerance of urban conditions and drought once established makes it a versatile and resilient landscape plant.

The large flowers are very attractive to a wide range of pollinators, including bees, butterflies, and hummingbirds. They provide a valuable nectar source late in the growing season when other floral resources may be scarce.

Care Guide

Do

Provide full sun for the best flower production.
Deadhead spent flowers to keep the plant looking tidy.
Water deeply during periods of drought.
Prune in early spring to maintain a desirable size and shape.

Don't

Don't plant in shady or wet, boggy locations.
Avoid excessive nitrogen fertilizer, which promotes leaves over flowers.
Do not prune in late summer or fall, as this will remove flower buds.
Don't worry if it's late to leaf out in spring; this is normal.
