We are in Texas & the picture is 2nd batch of tulips bought from my daughter's horticulture class. I'm a 1st time grower & all we have in our yard now are blue bonnets & yellow roses. I will probably take the above advice to dig them up & get rid of the ones in pots also. Guess it'll have to be viewed as a nice donation to the school this year;) i
I did call extension office but they are extremely busy so I'm still waiting.
