Young vine with tender growth and minimal branching; foliage emerges gradually

Water regularly, provide sturdy support structure, protect from strong winds, apply thick mulch around base. Plant in fall for spring blooming.

2

Vegetative Growth

6-12 months

Vine develops multiple stems and extensive glossy evergreen foliage covering the support structure

Provide secure support/trellis, apply balanced fertilizer in spring, prune lightly to shape and direct growth, maintain consistent moisture

3

Flower Bud Formation

4-8 weeks before blooming

Small flower buds appear along the stems in late winter, clusters of buds develop at leaf nodes

Reduce nitrogen fertilizer to encourage flowering, maintain good drainage, avoid pruning during this phase, ensure adequate light exposure

Flowering

6-10 weeks (typically February-April depending on zone)

Abundant clusters of fragrant pale pink and white star-shaped flowers cover much of the vine; petals have darker pink edges

Post-Bloom & Seed Development

Spring through fall

Flowers fade, interesting feathery seed heads (seedpods) develop; foliage remains attractive year-round

Allow seed heads to persist for visual interest, prune only to remove dead wood or shape, apply light fertilizer, prepare for next season's blooming cycle
