I planted a Dwarf Clematis ‘Zara’ (Evipo 062) last year. The tag that came with it said to “prune hard” to 6″ above ground in spring. Yet, it blooms in May.
Will pruning it in spring prevent/retard the blooming?
Clematis ‘Zara’ Evipo 062 was introduced at the Chelsea Flower Show in 2012 so it is a relatively new variety on the Canadian market.
This dwarf plant grows to be about 120 cm in height and produces blooms with pale blue petals and yellow centres. It grows best in partial shade and is ideal for container gardening. From my research, it is said to bloom in mid-late summer and early autumn. Pruning the plant back to 15-30cm, is done in early spring as flower buds are formed on new growth.
This plant is said to be hardy to US Hardiness Zones 4-9. Having said that, you may want to protect your plant from the Canadian winter as best as you can. If you have it planted in a container, cladding the pot with 2 inch Styrofoam board, placing it in a sheltered location away from cold north winds and mulching the top well with shredded leaves or hay, may help your plant survive. If it is planted in the ground, a generous helping of mulch and shredded leaves on top of the soil will help insulate vulnerable roots.
