With Baptisia × 'Decadence® 'Periwinkle Popsicle', you get a bold, upright false indigo that adds structure and cool color to your garden. This perennial forms a tall, vase-shaped clump and sends up spires of periwinkle-blue, pea-like blooms in late spring. Mature size is about 48-60 inches tall with a broad, leafy presence that looks great from spring through frost.
Plant it where it can settle in for the long haul, because Baptisia develops a deep root system and resents frequent transplanting once established. Give it full sun to part shade for best flowering, and choose soil that drains well. Water regularly during the first season to help roots establish, then aim for even moisture during extended dry spells. After bloom, you can leave the attractive seed pods for texture or remove them for a tidier look.
Use this variety as a focal point in mixed borders, as a backdrop behind shorter perennials, or as a stand-alone specimen in a sunny bed. Its upright form pairs well with ornamental grasses, echinacea, rudbeckia, salvia, and other sun-loving perennials. The flowers are also useful for cutting, and the sturdy stems hold their shape well in the landscape.
Routine care is simple: cut stems back after they die down in late fall or in early spring before new growth emerges. Avoid heavy fertilizing, which can reduce flowering and increase floppiness. Once established, you will appreciate how this long-lived perennial comes back reliably each year with minimal fuss.
