Mineru Blue Chiffon Rose of Sharon

Hibiscus syriacus 'Mineru'

The Story

Plant Bio

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

'Mineru', sold as BLUE CHIFFON, is celebrated for its large, lavender-blue, semi-double flowers with a lacy center of smaller petals. This variety is sterile or nearly so, preventing messy self-seeding and promoting a longer bloom time.

Uses & Benefits:

Blue Chiffon offers a rare and coveted blue flower color in the late summer landscape. Its large, intricate blooms provide a stunning tropical effect, making it a standout specimen, an informal hedge, or a vibrant addition to mixed borders.

Its strong, upright growth habit is ideal for creating vertical interest or privacy screens in the garden. As a sterile cultivar, it requires less maintenance than older varieties because there are no unwanted seedlings to remove.

The showy flowers are highly attractive to pollinators, including bees, butterflies, and especially hummingbirds. It serves as a crucial late-season nectar source, supporting wildlife when other floral resources are dwindling.

How to Grow

Select a location that receives at least six hours of direct sun daily.
Amend soil with compost to improve drainage and fertility.
Dig a hole twice as wide as the root ball and just as deep.
Place the shrub in the hole, ensuring the crown is at soil level.
Backfill the hole with soil and water thoroughly.
Mulch around the base to conserve moisture and reduce weeds.

Pro Tip

For the most intense blue color, ensure the plant receives full sun; shade can cause the flowers to appear more lavender.
