When to plant firecracker penstemon
A western perennial for full sun to part shade that demands excellent drainage and low fertility; do not over-water or over-fertilize. Sow seed outdoors in fall (it needs a long cold-moist stratification) or start it indoors after chilling, and divide mature plants in spring or fall.
