Clematis alpina 'Betina'

Stunning deep reddish purple flowers are 1-1.5" long.  Stems are also deep purple making an interesting contrast with the medium green foliage. 

Flowering period: Blooms mid-spring to late spring with a few flowers in late summer. 

Habit: Moderately fast growing deciduous climbing vine.

Height: 8-10'.

Exposure:  Sun to half shade.

Site: Any aspect including cold north or east facing ones.  Requires sharp drainage.

Recommended use:  Small gardens and patio's.  Useful  along pathways against walls or fences where you can enjoy the flowers close up. Suitable for large container culture.  Also used to cover the bare lower stems of clematis montana and wisteria vines.

Pruning: (Group 1)   When starting with a new plant prune as follows: during the winters of year 1 and 2 cut each stem ½ -1" above the lowest pair of active buds.  This will encourage low branching, giving you a fuller looking plant in later years.  Winter pruning after year 2 would be to cut each stem back to a strong pair of buds.  Remove dead or weak branches.  Hard pruning in winter will be at the expense of some spring flowers as they form on growth from the previous season.  You can prune this clematis to shape the plant in late spring after its main flowering period, with out the worry of cutting off potential flowers.    

Watering:  Likes regular water but suffers if it has wet feet. Requires good drainage.

Zones: 3-9.
