Baptisia australis/Blue False Indigo

And it was love at first sight, though lust may be more accurate.

Though slow to establish, Baptisia becomes a tough, drought-tolerant and low-maintenance plant. The flowers are followed by 2-inch swollen pods that turn black as they mature; the seeds inside rattle when after they've ripened.  Very cool! And some Baptisia-lovers recommend either cutting the spikes of the blue-black seedpods in midsummer for dried arrangements, or leaving them to add winter interest in the garden.

All baptisias are native to the Eastern U.S.  The only tricky part is that they're "slow to establish," which tests our patience.  And its deep taproot really doesn't react well to being moved. 

Details

• It grows to as large as 5 feet tall and wide, though the cultivar 'Purple Smoke' that I bought won't get larger than 3'. 
• Its May or June flowers last 2 to 4 weeks. 
• Hardy in Zones 3-9. 
• It takes full or partial sun, and seems adaptable to various soils.

 

Care

• It's drought-tolerant after it's settled in (after its first year in its new location).
• Tracy DiSabato-Aust recommends cutting back by 1/3 after flowering.  That's a tiny bit of maintenance for such a gorgeous plant.

Good Information in Print

• The Well Tended Perennial Garden by Tracy DiSabato-Aust is the best-selling book on how to make your perennials healthier and better-looking.
• Encyclopedia of Perennials by Graham Rice is exhaustive and an outstanding general resource on the subject.
• The Complete Flower Gardener by Cutler and Ellis is another source I consult regularly.
