Plan for at least 6 ft. tall.

oh yea of such faith ... relying on tag size .. lol ...

when i am in this circumstance.. i use a search engine to convert to the latin name.. and then flip to the images side ... and then look at all the pix ...

even embos 6 feet might be on the small size??? .. im not sure i would have room for 6 of them on my 5 acres ... or else.. i would become proficient with pruning .... there are some huge ones.. if you scroll down ...

The species grows typically between 6 and 10 ft tall. However 'Dart's Gold' is more compact than typical - I've seen it maybe head high or so*. But this would not have been the biggest and oldest one around.

*With really nothing in the picture like a marked off measuring stick to check against the "yikes" one linked to above may only be something like 6 ft tall also

Looks like I"m going to space them out a bit more then lol.

Ya Ken, I should have known better than to go with tag size, at least I caught it early.

You can prune these in interesting ways. I have a couple that I have turned into small, multi-trunked trees, which really shows off the bark.
