The Q&A Archives: Hibiscus 'red Sentinel'

Question: I just bought a hibiscus called "red sentinel". That's all I know about the plant. It's a dark maroon/purple all over, including the flowers (which is very abundant considering the size of the plant, about a foot high from one gallon nursery pot). The leaves are 3-lobed and deeply cut. I want to know how hardy this type of hibiscus is. All info that you can provide is greatly appreciated. Thank you.

Answer: HIBISCUS paramutabilis x syriacus is the botanical name of your 'Red Sentinel'. It produces large magenta flowers with a carmine eye. It blooms heavily until frost. The plants are hardy in your winter climate and can be planted outdoors. It's deciduous so the leaves will fall when the weather gets cold, but new leaves will develop in the spring. Provide full sun, well draining soil, and regular water during the growing season and your Red Sentinel should thrive.
