Decadence® Blueberry Sundae False Indigo (Baptisia 'Blueberry Sundae')

Decadence® Blueberry Sundae False Indigo (Baptisia 'Blueberry Sundae') is a compact, upright hybrid perennial with deep blue-green foliage. Profuse indigo-blue flowers rise above the foliage mound from late spring into summer. Large seedpods follow, turning black when ripe and adding ornamental interest.

It flowers best in full sun and dry to average-moisture, well-drained, acidic soil. Drought tolerant once established.

Safety note: The foliage is mildly toxic to mammals if ingested. Keep it away from pets and children who may chew plants.

Care and garden use

This low-maintenance perennial develops a shrub-like appearance as it establishes. Plants grown in shade may become taller and require staking. If trimming is needed, do so after flowering.

Baptisias serve as host plants for several butterfly species. Use in accents, grouped plantings, borders, wildlife gardens, naturalized areas, foundation plantings, or suitably sized containers. Pair with purple coneflower, goldenrod, or butterfly weed.
