mesemb seedlings

I’m growing about 90 varieties of cold-hardy mesembs. All of them, cold-hardy or not, need very cool temperatures for germination, less than 70 F (21 C). They germinate in two to four days at these low temperatures. They all look alike at this stage (a month old). The little touches of orange you see in between these cotyledon leaves are the first true leaves emerging. They will now begin to differentiate and after another couple of months they’ll look different.
