False indigos (Baptisia) produce large, spiky flower clusters in late spring to early summer. The bushy plants eventually reach 3 to 4 feet tall in bloom. U.S. native. Full sun for best flowering. Perennial; Zones 3 to 9.
A few years ago, I collected seeds from light purple ‘Purple Smoke’ growing close to pale yellow ‘Carolina Moonlight’, blue Baptisia australis, and bright yellow B. sphaerocarpa. (Since then, I added some white B. alba to the area as well.) They flowered for the first time in the spring of 2019. The photo above shows the range of flower colors I ended up with on these natural hybrids: a variety of blues as well as yellows, peach, copper, and white, as well as bicolors. The plants had a range of habits (from low and bushy to more narrowly upright), and a few had dark stems. I collected the seeds for sale here from what I considered the most interesting and colorful of those open-pollinated plants. I can’t guarantee what colors you will end up with, though. If you want a specific flower color, you’re better off buying a flowering plant of a named cultivar. But if you have space to fill and enjoy surprises, I think you’ll enjoy growing out these seeds as much as I have.
Harvested in August 2022. At least 15 seeds.
