I have been ordering seed from Silverhill for something like 20 years and have had the occasional mis-identified seeds and I would probably never buy certain genera again (from Silverhill or anywhere else) - Gasteria and Tylecodon have very, very seldom germinated for me, although one pkt. of Tylecodon from Silverhill did come up like cress. Even back some years, some batches of aloe seed, when inspected with a lens, were empty husk, complete with a hole where the weevil or whatever exited.
I hear rumours of a higher than reasonable number of misidentified species, but that apart, sad to tell, seed from Lifestyle has much to recommend it over Silverhill - standard pkts. are 100 seeds, (though plenty of rarer spp. are offered in smaller quantities), locations and harvest dates are given and their website is updated whenever anything new arrives in stock. They also stock lots of ephemeral species (which usually sell-out fast).
