Name: Toni Denver Metro (Zone 5a) Whiskey Tango Foxtrot.
This is actually from the blooming season last year.. Looks like 4/15/15 is when I took that picture. This is of a "common purple" lilac that's probably.. oh.. 30? 35? years old. He's a HUGE bush that I really really need to trim down, but I've just be so lazy.. he's in the corner of my front yard. The fence is a 6' privacy fence that he peeks over.
No where near blooming time yet. Probably not for another month & half. Should get a good season this year w/all the snow we had earlier. You definitely need to winterwater these badboys if you want good blooms in the spring. But I neglect this plant so horribly.. I never water/feed it.. he sits in some of the worst soil on the planet, he's got riverrock underneath him and ever year, I get tons & tons of blooms.
