Growth Stages

Establishment

Year 1

Young shrub with upright growth habit gradually taking on weeping form; limited foliage

Water consistently during first year. Avoid transplanting established plants. Mulch base lightly. Prune minimally to allow natural form to develop.

Vegetative Growth

Years 2-3

Branches elongate and begin cascading downward; fine, fern-like foliage emerges along stems

Water as needed during dry spells. No fertilization needed; performs well in poor soil. Allow natural weeping form to develop without excessive pruning.

Flowering

3-4 weeks in spring

Small, bright yellow pea-like flowers appear along drooping branches in spring (May-June)

Enjoy flowers without deadheading; seed pods add late-season interest. No supplemental care needed during bloom.

Fruiting & Maturation

Summer through fall

After flowering, small elongated seed pods develop and mature; foliage remains fine and feathery through summer

Allow pods to mature for ornamental interest; can leave on plant through fall. Minimal watering needed once established.

Dormancy

Fall through spring

Deciduous shrub loses fine foliage; weeping branch structure becomes prominent in landscape

No watering required. Prune only if necessary to remove dead wood or crossing branches. Structure provides winter interest.
