The
hardy hibiscus is considered a perennial because, even though
they have woody stems like a shrub, they die back to the ground
each winter. They are hardy to zone 4 and with winter protection,
they can be marginally grown in zone 3.
Traditionally,
the hardy hibiscus were large plants with large medium green
leaves. Plants sizes today vary greatly. Many of today’s
varieties offer smaller leaves on more compact plants. The
more compact hardy hibiscus also exhibits incredible flower
colors. Botanically, the hardy hibiscus plant is known as
Hibiscus moscheutos. |
