Hey Carl, thanks for the reply. I love Serissa too. Wow they really do flower. Mine never get that many. I live in zone 6 so the winter temps should be similar, maybe a little colder here. Do you protect them in any way (mulch, cover them, etc)? I was just thinking of ground planting stuff during the warmer months, but doing it for the whole year would be even better. Serissa would probably be the exception rather than the norm, I have read they can handle much colder temps (in the 20's)than most tropicals (keep above 50). But very interesting, thanks for your comments. I have some serissa cuttings that have rooted, maybe I'll plant half next year in open ground and the others not and see what happens. Then I can compare how they grow. I took a look at your site too, very nice artwork. I'm an illustrator;-) Thanks!
