Tickseed coming up every year

Question

I have little sprouts of my tickseed coming up. Two are about 4-5″ and are growing on last year’s plants. The rest are 1-2.” There are hundreds. Are they going to get big like the original plants? Should I thin them?

Answer 1

Certainly, they reseed themselves easily in the right setting and can even become invasive.
