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: Fruit on Jasmines
Answered by: Anne Van Nest

QUESTION:

My jasmines have grown some small purple fruits and she is about to get her full bloom soon. Should I cut them off to help the plants out? What are they?

ANSWER:

Thanks for your question. Mr. Smarty Plants is having trouble determining which plants you are growing that have small purple fruit. There are many plants, both natives and non-natives that are called jasmine. Below are the North American natives that we have in our database, but none if these seem to have purple fruit.

Blue jasmine (Clematis crispa)

Lehmann’s rockjasmine (Androsace chamaejasme ssp. lehmanniana)

Pygmyflower rockjasmine (Androsace septentrionalis)

Swamp yellow jasmine (Gelsemium rankinii)

Anyway, even though an exact identity isn’t known, in general, when plants set fruit they do divert energy and resources from growing and flowering to getting their fruit to mature and ripen so they can reproduce. But whether your plant is going to suffer because the fruit is maturing – only you can decide. If the plant is small and weak, it is recommended to prune out the fruit so that energy is not diverted. If you plant is vigorous, healthy and strong, keeping the fruit on won’t harm it and if you want to start more from seed (and your plant isn’t a hybrid), you may want the fruit to mature.
