Our winters in the bay area range. Mine is 10a,lows each year near 32f,but not under 30 in general. SF is 10b,but I guess I don't need to explain the SF summers. Yet- people would be shocked at what can grow there from the subtropics. Some low spots in the bay area are 9b..pretty rare for close to the bay.
Me? I have a very small lot,and as you can see,my plant interests cross the whole spectrum. Still,I have a 30 year old Suebelle Sapote I planted,Meyers Lemon,Bailys Marvel Mango,and that Ice Cream banana- with banana's on it now. In the past I've grown Cherimoya to fruiting from the exclusive regions of Safeway market
Avocado's to huge fruit from a pit. Something killed that and the guys across the street. I miss that tree. Big creamy fruit...like little cannonballs I used to say.
I know others have grown Pineapple outdoors in Hayward. Read it in the paper. I have coffee too.
I have met these types before. A decade ago the owner of a local cloudforest website and soucalian posters!..told me Bizmarckia palms could NEVER grow in the bay area..just too-too cold. Well,I proved them wrong. I grew one and have taken pictures of them around over my city and area. He wanted to ban me from saying people should try Mangoes..as I said my Manila made the SF Chronicle. Now? I read he's encouraging people to try them..lol Un freakin believable. I think Barath and Myrna are also in the Mango club now
I have a real background in natural sciences and Biological sciences..anybody else here ever grew Arabadopsis for a bio lab? I did..lol. A ugly weed..but important!
So,that's the short list. I would rather brag about my cat.
