Evan, that is my problem too- can't find them or forget them if there isn't any foliage present. Last year I'd planned do dig these from the lawn, and we took a trip the first week of June unexpectedly. When we left the foliage was just starting to flop and yellow on the tips, but when we returned I couldn't find them! Once they start going, they go fast. It was hot and humid here while we were on our trip last year, so that probably sped things up. Same this year, we're having temps in the upper 80s and low 90s this week, and it's been really muggy.
