Of course they would not survive ---- here ---- outdoors. That is what the insides of houses are used for here in Winter.
I have both the Gomphocarpus here in the ground and in about 3 weeks I will pot them up. Neither are hardy here in Zone 5B.
I had tons of Cats on the fruticosus. Unfortunately 3 inches of rain in 20 minutes wiped away ~ 12 of them. Wahed away - literally (that was from your seed).
You are now part of RobinSeeds? Cool.
You guys moved to Etsy? Sale?
WRT Zone 9 plants, I have maybe 5 - 6 dozen. Counting my little tykes grown from seed, I am up to 27 or so Plumeria.
