P. vitifolia hardiness
Last time I posted I think I mentioned that the plant (p. vitifolia) was not winter hardy this far north (z8, coastal carolina). However, this year the plant seems to have resprouted from its root. Its about a 1.5 feet tall now, and seems very healthy. I'd no idea that it was able to do this.
A lot of the tropical stuff came back for me this year and this is the first time that has happened. Several species of tropical jasmine, Thunbergias, Tecomaria capensis too.
And unlike P. incarnata, which is a completely herbaceous perennial here, caerulea seems to have made it without even loosing a lot of its foliage.
Wonder if I can count on this development.
