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: Problems with non-native yellow lantana from Elgin TX
Answered by: Barbara Medford

QUESTION:

Why do my yellow lantana buds turn brown and do not open fully? The sprinkler system does not spray onto the lantana.

ANSWER:

While there are 4 lantanas native to North America and 3 native to Texas, none of them are yellow, which may mean that you have the hybrid Lantana camara 'New Gold', which is not considered native. Our focus is on plants native not only to North America but also to the areas in which the plant grows natively. Since you live in Elgin, you might have purchased Lantana urticoides (Texas lantana) from the Wildflower Center Plant Sale, but it is not yellow. The other two native to Texas are Lantana achyranthifolia (Brushland shrubverbena) and Lantana canescens (Hammock shrubverbena).

Although this sounds like an insect problem, possibly whiteflies, it also could have to do with how much sun the plants are getting. The natives require full sun, which is 6 hours or more of sun a day, and are low water plants.
