Breck's -- good experience!
Just wanted to post that I've had a great experience, so far, with Breck's. I seem to recall hearing bad things about them in the past, so I was somewhat hesitant about ordering from them, but took the plunge--and I'm glad I did.
I ordered a large number of plants, including various dahlias, geraniums, sage, sedum, bleeding hearts, and more. My order was split into three deliveries [based on when to plant], of which I've received two; the remaining delivery should come next week. All but one of the plants I've received have been in excellent condition, carefully packed, thriving, and basically exploding with growth as soon as they were put in the ground. One of the geraniums did not grow; I contacted Breck's and they immediately sent out a replacement.
Each plant had very clear, very thorough planting instructions, including which plants needed to be soaked in water for 30 minutes prior to planting.
I have no complaints at all thus far. If my opinion changes, I'll post an update!
