Difference between Dreamweaver and Purple Spire crabapple?
I am looking for a columnar crabapple that's good for Calgary (zone 3). I have read about the Dreamweaver and Purple Spire crabapples. They look incredibly similar to me! Then in one place, they even state that the Purple Spire is part of the Dreamweaver series!? Hmm.... really?
Then there is also the Emerald Spire crabapple.... which is supposed to have greener leaves than the bronzy purplish leaves of Purple Spire.
What are the differences really??? Which one is the best bloomer?
If I want columnar trees but I don't want a columnar crabapple or gasp... Swedish Aspen (they are so overused in my neighbourhood!), what are my other choices? The area in question will need three of them in a row. It also gets a decent amount of sun.
