About White Passionflower

Passiflora caerulea 'Constance Elliott' · also called White Passionflower, Constance Elliott Passionflower · flowering

Passiflora caerulea 'Constance Elliott' is a vigorous, fragrant white-flowered cultivar of the blue passionflower, awarded the RHS Award of Garden Merit. Hardy enough to overwinter outdoors in much of the UK with root protection, it produces a succession of ivory blooms through summer followed by orange fruits. Ideal for a sheltered sunny wall.

Plant type: flowering

The reasons white passionflower isn't blooming

Almost every non-blooming white passionflower 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 white passionflower 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 white passionflower to flower

Maximise sun. Give white passionflower 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 white passionflower and get the feeding right with the white passionflower 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

White Passionflower 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 white passionflower care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

White Passionflower blooming — frequently asked questions

Why won't my white passionflower flower?

White Passionflower blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
