The Story

Plant Bio

Hibiscus syriacus, or Rose of Sharon, is a hardy, deciduous shrub valued for its large, tropical-looking flowers that bloom in late summer when few other shrubs are flowering. It has an upright, vase-shaped habit.

AZURRI BLUE SATIN is notable for its large, single, rich blue flowers with a contrasting red-purple eye. Uniquely, it is sterile or produces very little seed, preventing the nuisance self-seeding common to the species.

Uses & Benefits:

Provides a long season of vibrant, tropical-looking flowers in late summer and early fall when many other shrubs have finished blooming. The rare blue flower color is a standout in any landscape.

Can be trained as a small tree or used as a tall, deciduous hedge or privacy screen. Its tolerance of urban conditions and drought makes it a tough, versatile plant.

The large, open-faced flowers are a valuable late-season nectar source for hummingbirds, bees, and butterflies, supporting pollinators when other food sources are dwindling.

Care Guide

Do

Provide full sun for the best flowering.
Prune in early spring to maintain a desirable shape and size.
Water deeply during prolonged drought.
Deadhead spent flowers if desired, though not necessary for this sterile variety.

Don't

Don't plant in soggy, poorly drained soil.
Don't prune in summer, as it blooms on new wood from the current season.
Avoid heavy nitrogen fertilizer, which can promote leaves over flowers.
Don't worry if it's late to leaf out in spring; this is normal.
