Establishment
4-6 weeksYoung transplant developing root system and initial branching
Water moderately to establish roots over first 4-6 weeks. Avoid overwatering. Provide bright light and protection from harsh afternoon sun if newly transplanted.
Vegetative Growth
Spring to mid-summer, 8-12 weeksVigorous shoot and foliage development with lance-shaped green leaves
Encourage branching by light pinching of stem tips in spring. Reduce nitrogen fertilizer—too much causes leggy growth. Maintain well-draining soil.
Flowering
Late summer through winter (August-December), 4-6 months in warm climatesAbundant tubular red flowers appearing on stem terminals; attracts hummingbirds
No deadheading required but light pruning after first flush can encourage reblooming. Do not over-fertilize. Continue minimal watering. Flowers persist for weeks.
Winter Rest
Winter months, 2-4 months depending on zoneReduced growth and flowering; partial leaf loss in cooler zones; may retain foliage in mild climates
Minimal to no watering unless in active growth. Provide frost protection in zones 8-9 with mulch or shade cloth if temperatures drop below 20°F. Avoid pruning until spring.
Spring Renewal
February-April, 4-6 weeksNew growth emerges; old stems can be cut back for shape and rejuvenation
Prune back to 12-18 inches in early spring to encourage bushier growth. Remove any frost-damaged wood. Resume regular watering as growth resumes.

Harvest Tips
This is an ornamental shrub grown for flowers rather than harvest. Flowers can be cut for short-lived fresh arrangements; cut in early morning when stems are turgid. Prune stems back by 1/3 to 1/2 in early spring to rejuvenate plant and encourage dense branching. Remove dead wood anytime.
