Establishment
2-3 monthsYoung transplant with compact foliage; root system developing
Water regularly to keep soil moist. Mulch around base with 2-3 inches of peat or pine bark. Protect from wind and harsh conditions. Do not fertilize.
Vegetative Growth
Spring through early summerPlant fills in and develops branching structure; foliage thickens
Continue regular watering. Light pruning after flowering encourages bushier growth. Avoid high-nitrogen fertilizers which cause weak growth.
Flowering
6-12 weeks (varies by variety and season)Delicate, tiny bell-shaped flowers appear in spikes; colors range from white, pink, purple, to red depending on variety
Maintain consistent moisture during bloom. Do not overwater. Enjoy the flowers; many varieties bloom for 2-3 months. Deadheading extends bloom in some types.
Dormancy/Winter Interest
October-MarchMany varieties show seasonal foliage color changes to bronze, rust, or yellow. Flowers may persist as decorative seedheads
Reduce watering in winter but do not let soil dry completely. Protect from harsh winds. Foliage color is a feature—do not deadhead if seed heads are attractive.
Dormant Rest
December-FebruaryMinimal growth; plant conserves energy
Light pruning in late winter or early spring to maintain shape and remove dead wood. Prune before new growth begins.
