Constance Eliott Passion Flower. This lovely form has pure white flowers on a vine that is just as vigorous and easy to grow as the Blue Crown Passion Flower. The flowers have a delicious, fruity fragrance that smells like guavas. Hardy to 15 degrees F! If the top is damaged by frost, it will sprout from underground, tuberous roots. This is a very large vine, so it will need a lot of room. It is ideal for covering fences and screens rapidly.
Although P. 'Constance Eliott' appears to be similar to P. 'White Wedding,' in person they are very different. P. 'Constance Eliott' is much more delicate with a fruity fragrance, while P. 'White Wedding' has larger flowers with thicker, spongier petals and thicker filaments. The P. 'White Wedding' also has a larger, huskier vine and is less cold-hardy.
Light: Full sun, part shade. There will be less flowers in part shade.
Soil: A wide range of soil, but it must be well-drained.
Fertilizer: A slow-release, bloom-booster type fertilizer is appreciated, but beware of using a fertilizer with too much nitrogen as it may push leaves at the expense of flowers.
Hardiness: Zone 8 or lower in a sheltered site.
