Firecracker Penstemon: Winter-to-Spring Color for Dry Gardens

Distinguishing Traits

Provides rare winter color when little else blooms. Flowers persist into spring. Despite delicate appearance, it’s unfussy: no fertilizer needed, just annual removal of spent spikes.

Companion Plants

Pair with yellow-flowered angelita daisy (Tetraneuris acaulis), brittlebush (Encelia farinosa), damianita (Chrysactinia mexicana), or white Blackfoot daisy (Melampodium leucanthum) for striking contrast.

Landscape Uses

Versatile: along desert washes, around trees, by pools, along paths, as a single accent by a boulder, or in wildflower seed mixes.

Planting Notes

Grow from seed or nursery containers. Requires well-drained soil. Water established plants weekly in summer, every other week in cooler months.
