Have read that Crocus tommasinianu is "squirrel-resistant", is small enough to naturalize in a lawn, and spreads well via seed. So I know you are not supposed to mow them until the tops die off but the only article I saw that gave time periods said it flowered in February, and not to mow until June!!! This won't be an option for me as the grass would be high enough to mow for hay! But I am unsure if that applies to Kentucky/southern Indiana area. Does anyone grow this species in my area? Do the tops persist that long here? Can anyone comment on the "squirrel-resistance"?

I usually just wait until the tops turn yellow; start flopping over... than mow away. Mn here.

June?

Just guessing, but thinking its about 3-5 weeks after coming up, I usually just leave the patches alone until they leaves have yellowed and starting to flop over, for me the grass gets about 4 inches tall. You could raise your your lawn mower to a higher setting to go over the top of the leaves. They don't get that tall.

I grow Lilac Beauty, and it is one of the few crocus that has not been fully destroyed by the critters.

The foliage is very small, and mine does not stay around until June. The leaves blend into the pine straw when they die off, I've never had to remove them for being unsightly.

What a lovely little flower. Must look it up to see if it will survive here. Or I suppose I could pot it up and store it over summer and winter??
