Growth Stages

1

Establishment

First growing season (4-6 weeks critical)

Newly planted shrub with developing root system and initial leaf growth

Water deeply 2-3 times weekly for first 4-6 weeks. Apply 2-3 inches of mulch around base. Avoid fertilizing first year to prevent soft growth.

2

Vegetative Growth

Spring and early summer

Shrub develops full foliage with burgundy-red young leaves maturing to variegated cream-pink-burgundy coloring

Monitor for consistent moisture. Apply balanced slow-release fertilizer in early spring. Prune lightly to shape if needed after flowering.

3

Primary Flowering

Late spring to early summer (4-6 weeks)

Dense clusters of tubular burgundy-red flowers appear along stems

Deadhead spent flowers to encourage repeat blooming. Avoid heavy pruning during flowering. Monitor for spider mites in hot, dry conditions.

4

Summer to Fall

June through September

Foliage becomes fully variegated with cream, pink, and burgundy tones; intermittent secondary flowers may appear

Continue regular watering during dry spells. Apply second application of balanced fertilizer in midsummer for repeat blooms. Watch for Japanese beetles.

5

Dormancy

November through March

Leaves drop in fall, shrub becomes dormant through winter; structure becomes visible

No watering needed. Prune in late winter before spring growth begins. Remove any dead or damaged wood.
