Common questions
Why do the flowers only last a day?
That's normal. Healthy plants produce a steady supply of new buds.
Can it grow indoors?
For winter, beside a sunny window. It's happiest outdoors in warm months.
When should I prune?
In early spring, cutting back by up to a third.
Is it the same as the hardy hibiscus?
No. Hardy hibiscus is a different species that dies back in winter.
