In late April, I got to see the tall Trachies at the Royal Rose Inn (which is no longer a B&B) in Rehoboth Beach, DE. My girlfriend took pics with her cell, but she has yet to send them to me. When I get them, I'll share them on the board.
The Royal Rose's plant palette has changed a bit over the past 10 years. One of the Polar Vortex winters took out the two big (and they were BIG) Trachies out back. The Trachies in the front yard survived and look great today. In the front there are also nice Needles and Minors. There USED TO BE a thicket of Yucca Aloifolia in the "median" between the sidewalk and the road, but I'm almost positive that the city prevailed upon the owners to rip them out of there as a pedestrian safety issue.
Back in the day, the Royal Rose had Monkey Puzzles and Oleanders too, but they bit the dust some years back. The property was a FANTASTIC 7b laboratory test plot, if you will. What was learned (as if we didn't already know) is that Oleanders are difficult even at a coastal 7b location. Trachies are long-term 50/50. If you have 4 mature ones, after a decade or two, you might have 2 survivors. Minors and Needles are good to go. They may damage in the very worst winters, but you shouldn't lose any of them.
The loss of the Monkey Puzzle is more of a mystery. I've seen them in this area (7a) and at the New Jersey shore (7a/7b). Never seen them succumb to cold, only chainsaws. Perhaps it was removed intentionally like the Yucca.
Below is the Royal Rose Inn as it used to look before the very cold winters came.
