I'll be really interested in the responses here. I was given a small redbud that was obtained from some kind of Arbor Day promotion. Redbuds are abundant here in Texas. The one I've been growing now for about four years doesn't leaf out very early at all. Other redbuds have bloomed and are covered with foliage before mine breaks dormancy. It looks like a redbud in every way as far as the leaves and plant habit. It has never bloomed and is still relatively small. In the beginning I thought it might have died, but the growth is healthy - just very late. So I've been guessing it's not the same redbud that I'm accustomed to seeing primarily because of its habit of breaking dormancy late. I think those in Texas are called western redbuds. The question would be for someone knowledgeable with both plants, if that is correct, who might know if there's a significant difference when they break dormancy.
