Inventor: Uno and Aili Kivistik, Estonia
Colour: lilac blue
Blooming Season: June through September
Mature Size: flower size 16-18cm diameter/ vine H 180 cm W 80cm
Care: Plant in sun to partial shade in fertile, well-drained alkaline soil. Dig a hole 12 cm deeper than the root ball, then plant with enriched soil, ensuring the top of the root ball is slightly higher than ground level. Back fill with enriched soil.
Regular deep watering is important to ensure the root ball does not dry out. Fertilize consistently with a well balanced general fertilizer beginning in April at start of growth. To keep roots cool, use mulch to reduce the soil temperature. A once-a-year application of lime will do the trick. This Kivistik clematis has repeat blooming, so prune old flowers after finished, and you will enjoy more blooms.
Ilka is well suited for cold climates and can be pruned 30cm from the ground and then mulched before winter. It has been bred and tested for the climates of Estonia (group 3) with disease and insect resistance as well.
