The Redbud tree is a vibrant and long-term bloomer. They’re strong and versatile and can live in nearly all US hardiness zones (4-9, and some in zone 10). They’re found all over the country and can also grow in most soil types. Each pack comes with 20 seeds and basic instructions for germination. I’m a USA seller which means faster shipping times as well as higher quality seeds. A vast majority of my seeds either come from my garden, from my neighborhood or in the local area. If not, I’ve acquired them on trips around the country. I’ve tested and grown many of these myself. I’m always here for assistance with germination and growing. Your success is my success!
