Decadence® Deluxe Periwinkle Popsicle™ False Indigo

Decadence® Deluxe ‘Periwinkle Popsicle’ is an upright, vase-shaped false indigo with green foliage and dark periwinkle-blue flower spikes. It blooms later than many Baptisia selections, extending the late-spring color sequence in sunny borders and naturalistic plantings. ## Landscape use Use this tall, narrow clump to fill a border or soften the front of a shrub planting. The [Proven Winners profile](https://admin.provenwinners.com/plants/baptisia/decadence-deluxe-periwinkle-popsicle-false-indigo-baptisia-hybrid) identifies the blue-periwinkle flowers and its later-than-usual flowering; [Walters Gardens](https://www.waltersgardens.com/variety.php?ID=BAPPE) confirms the cultivar identity and blue flower color. ## Size and siting Published mature size is roughly 4–4½ feet tall and 3½ feet wide. Allow room for a permanent clump, since Baptisia develops a deep taproot. Full sun to part sun and well-drained soil are suitable; the genus-level [North Carolina Extension guidance](https://plants.ces.ncsu.edu/plants/baptisia/common-name/baptisia/) describes tolerance of dry and poor soils. The breeder lists USDA zones 4–9. ## Maintenance Water during establishment and extended dry spells. Once established, this cultivar is described as drought tolerant. Routine deadheading is unnecessary; keep the ornamental seedpods for fall interest or trim stems after they have finished if you prefer a neater border.
