Beavercreek Greenhouses

this place has an online/mail ordering business;
mostly alpines and rock garden plants, hardy cacti etc --an amazing list! there are about a dozen semps on the list..
i have not yet ordered from them, but they come highly recommended..
from the mountains of british columbia, zone 3, i think

I've ordered from them, and although some of the plants were great and a good size (their packaging is interesting!) there were a few that were disappointing - mainly the Orostachys that I ordered came labeled Orostachys, but was actually Sedum dasyphyllum - the most expensive Sedum I've ever bought! The service was good in some ways (Roger sent the package on the bus, and it arrived the same day - before I even sent payment) but my question about the Orostachys remains unanswered...
