Q. Who is Mr. Smarty Plants?

Title: Smarty Plants on Fan Scarlet-Cardinal
Answered by: Nan Hampton and Joe Marcus

QUESTION:

I have a lobelia x speciosa (Fan Scarlet-Cardinal) plant and was wondering if I should dead head it after blossoming so that the plant continues to flower. Can you help? Thanks!

ANSWER:

Since it is so late in the growing season, deadheading your Fan Scarlet-Cardinal is not likely to result in a new flush of blooming. However, if you want to tidy up your garden, it won't hurt to deadhead the plants and remove the seeds since the seeds that fall won't be true breeding to produce your hybrid again. Next year if you want fuller, shorter plants with more flower spikes, you can try pinching back your hybrid lobelias early in the growing season.
