All I can tell you is the RDV from Palatine's is 38" inches tall. And I did not measure it straight up and down because it's bent around the obelisk. So it's really taller than 38". I planted it last Spring. The other 3 RDV were planted 4 years ago and one is 18" tall, the second one is 14" tall and the third is maybe 12" in height. The older I get, the more "time" has become important factor to me.
