3 years ago I spent $18 on a dinky little double flower helleborus and Steven almost killed me. (The single flower sort were 1/3 the price and twice as big.) I knew it was ridiculous, but I'd seen a photo of the double flower and I had to have it.
The last few years it hasn't done all that well (it was in the path of the pooches) but last year I moved it and it's going gangbusters now!
Steven even admitted it's way more than 18 bucks worth of pretty.
