About Clematis 'Warszawska Nike'

Clematis 'Warszawska Nike' · also called Warsaw Nike clematis, velvety purple clematis · flowering

Clematis 'Warszawska Nike' is a richly coloured deciduous climber with deep velvety royal-purple flowers and golden anthers, blooming from early summer into autumn. Often grown as Pruning Group 3 but flexible, it flowers reliably on new wood when cut back hard. Plant in sun or light shade with the roots kept cool and shaded.

Plant type: flowering

Watch for — Colour bleaching: Strong sun can fade the deep purple petals. A spot with some afternoon shade keeps the velvety colour rich while still allowing free flowering.

The reasons clematis 'warszawska nike' isn't blooming

Almost every non-blooming clematis 'warszawska nike' traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding clematis 'warszawska nike' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get clematis 'warszawska nike' to flower

Maximise sun. Give clematis 'warszawska nike' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for clematis 'warszawska nike' and get the feeding right with the clematis 'warszawska nike' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Clematis 'Warszawska Nike' flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full clematis 'warszawska nike' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
