I am in zone 9. I have (3) cultivars of Tibouchina, a dwarf Tib, velvet H. Tib, and the A. Tib...
allamandas (yellow&cherry jubilee, shrimp plant (yellow), red on black stem crapes, white Natchez crape, Texas sage, and a unique pink flamingo flower. As well as a good bit of red Japanese Ixoma, and really vibrant Persian shield cuttings for trade.. and I almost forgot crazy good double hibiscus flower. (Confederate rose) just don't like the name.
Happy to trade for seed, cuttings, or others.
