Eranthemum pulchellum (Blue sage)

Eranthemum pulchellum, commonly known as Blue Eranthemum or Blue Sage, is an evergreen shrub native to the Indian subcontinent. It typically grows 3-6 feet tall, forming a dense, upright plant with glossy dark green leaves that provide an attractive backdrop for its vivid floral display. Although handsome throughout the year, it is most spectacular during the flowering season.

The plant produces dense terminal spikes of large, funnel-shaped flowers in shades of rich violet-blue to lavender-blue, often with a white throat. Flowering usually occurs during the cooler months, when relatively few tropical shrubs are in bloom, making it especially valuable for winter color. Unlike many members of the Acanthaceae family that flower intermittently throughout the year, Eranthemum pulchellum often produces a particularly abundant seasonal display. It grows best in full sun to partial shade and fertile, well-drained soil with regular moisture. Light pruning after flowering helps maintain a compact shape and encourages vigorous new growth. Suitable for USDA Zones 10-11, it is widely grown as a specimen shrub, flowering hedge, or container plant in warm climates and can also be cultivated as a conservatory or greenhouse plant in cooler regions.Learn more about Eranthemum pulchellum: Blue Sage: Winter Wonder.
