Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Care for non-native tropical hibiscus in Houston
Answered by: Barbara Medford

QUESTION:

How to care for a tropical hibiscus plant? How much water, sun, fertilizer? I am novice gardener in Houston, TX. From much reading, April seems to be the month I cut all blooms and let the plant lie dormant. Please help, I am confused.

ANSWER:

Since you are a novice gardener, we invite you to read our How-To Article A Guide to Native Plant Gardening. Tthe Lady Bird Johnson Wildflower Center is committed to the use, protection and propagation of plants native not only to North America but to the area in which those plants are being grown, so the Tropical Hibiscus would fall out of our range of expertise. 

There are 13 members of the Hibiscus genus native to North America, 11 native to Texas and two, Hibiscus lasiocarpos (rosemallow) and Hibiscus laevis (halberdleaf rosemallow) native to the Harris County area. Those, however, are not what you could ordinarily refer to as "tropical" hibiscus. You likely have a hybrid of Hibiscus rosa-sinensis, probable origin tropical Asia, much cultivated and hybridized.  You can follow the plant links above to the pages in our Native Plant Database on the Hibiscus native to Harris County, and may learn the answers to some of your questions. We would also refer you to these websites that are NOT confined to natives and have a great deal of information:
