Growth Stages

1

Establishment

First growing season

Young plant is small and compact with emerging needle-like foliage

Keep soil consistently moist but not soggy. Protect from harsh winds. Mulch with sand or grit, not bark. Avoid planting too deep.

2

Vegetative Growth

Year 1-2

Plant gradually expands in width and height, producing dense, fine-textured foliage

Pinch back stem tips in early spring to encourage branching. Maintain even moisture. Light feeding with low-nitrogen, acidifying fertilizer acceptable.

3

Flowering

June-November

Terminal flower spikes emerge with bell-shaped tubular flowers in shades of pink, magenta, or white; blooms appear continuously

Flowering begins midsummer and continues into fall. Deadhead spent flowers to promote continuous blooming. Ensure adequate sun exposure.

4

Peak Maturity

Year 3 onward

Plant reaches full landscape size as a rounded mound with abundant flowering potential each season

Prune lightly after flowering or in early spring to maintain shape. Replace plants after 10-15 years if they become leggy.
