Baby, It's Cold Outside!

... And yet several different kinds of perennial plants in my garden just don't seem to care! In fact, they seem to be thumbing heir noses at Mother Nature!

As of this writing, it is late October in Omaha, Nebraska. We have had a few consecutive nights hovering in the high 20's and low 30's a few times, which is usually the death knell for most plants, perennial or otherwise.

Yesterday our high was around 40 and the temps kept dropping all afternoon down through the 30's. By evening we were in the upper 20's. When I went outdoors to go out, i was in for a big surprise... my "Stupid Dahlia" had bloomed!

My Stupid Dahlia Plant! - It really IS stupid!

I planted two Dahlia bulbs last Spring. They grew into huge, healthy plants over three feet tall. I kept waiting for a big profusion of blooms. Never happened! In September, one lone bud finally appeared on one of the plants. We had an early freeze in mid September so I was pretty sure I would never see what that Dahlia looked like!

The other day, our temps dropped suddenly and by mid afternoon we were at about 34 - and it was to be in the 20's that night. OK, the dahlia was now pretty pathetic looking, lots of frost damage all over the plant. But the bud itself looked healthy. When we left for dinner later that night, to my shock, the stupid Dahlia was blooming at 30 degrees!! I picked it as soon as we got home and brought it inside so I could at least see what the flower looked like!
