Hi,

I'm curious whether anyone knows the cold tolerance of Alyogyne hakeifolia (formerly Hibiscus hakeifolia). It should be fine where I live--I'm curious about other areas--cuttings are supposed to root easily. I'm interested in the yellow form in particular. Here are pictures/info:

If possible, I'd be interested in something more precise than just the USDA zone--a temperature at which someone's plant survived would be interesting. The Sunset zone may also be interesting.

The plant is in the same genus as the blue Hibiscus, but its leaves are needle-like.
