Vegetative Growth
6-8 weeks (May-July)New stems and foliage develop; plant continues climbing; older flowers fade, replaced by decorative feathery seed heads
Water regularly; guide growth with soft ties; remove spent flower stems if desired; watch for pests; thin crowded growth if needed
Seed Head Development
8-10 weeks (July-September)Decorative silvery, feathery seed heads (achenes) replace flowers, adding ornamental interest; foliage matures to full green
Leave seed heads for visual interest through fall and early winter; water moderately; reduce fertilizer; no major pruning
Dormancy
4-5 months (October-March)Foliage dies back or becomes sparse; plant enters winter rest; previous year's woody stems remain as framework for next spring's growth

Small Space Gardening

Fun Facts
- 🌱 Clematis alpina 'Ruby' is named for the Austrian Alps where the Clematis alpina species originates, making it one of the hardiest clematis varieties and suitable for cold climates where other clematis may struggle.
- 🌱 The plant belongs to Clematis Group 1 (pruning group 1), meaning it flowers on old wood from the previous year and requires minimal pruning—simply remove dead or damaged stems in spring.
- 🌱 The feathery seed heads, called 'old man's beard,' persist through winter and are actually modified styles that help with wind dispersal, making them both beautiful and biologically functional.
