Title: Eliminating bluebonnets from lawn
Answered by: Nan Hampton
What a shame to lose your beautiful bluebonnets!
Lupinus texensis (Texas bluebonnet) is an annual that grows from seed each year, the seeds that most likely fell from your plants in late May and June. By now you probably can see the rosettes of the seedlings already growing for the plants that should bloom in March and April (see photos below). These will be very easy to dig out since they should still have very shallow roots. This will eliminate any bluebonnets next spring. You will need to keep checking during the spring to be sure that you have dug them all out. This doesn't mean, however, that you won't have new plants emerge next fall/winter since not all seeds will germinate the first year. Indeed, you may have several plants show up for several years, but those plants won't produce new plants unless you let them go to seed.
Mr. Smarty Plants is very sorry for your loss!
