Gardenweb doesn’t have that kind of forum, but there are some swap or exchange forums. In the meantime, you might try your local Freecycle or neighborhood garage sales.,

Sign up for Next Door. I'm sure people there would be happy to share cuttings or extra plants.

I don’t see freecycle supports Texas locations. Just San Jose. I remember using it when I was there and it was quite useful. But I am pretty stuck here. Anyway thanks I will keep a lookout

I give away tons of plants and cuttings on Nextdoor. We even started a Plant Lovers group and have swaps at least once a year.

Nextdoor, facebook garden groups, freecycle. I've given through all.
