Passiflora alata seed
P. alata is an evergreen climber to 6m or more, with 4-winged stems and large 3-lobed leaves. Flowers 12cm across, fragrant, bowl-shaped,
With its beautiful, fragrant flowers, Passiflora alata is a definite favorite among passion flowers.
Flowers appear on new growth, so any pruning should be done early in the season. Can be grown in a large container too.
It is recommended to pretreat Passiflora seeds before planting. They contain a hard coat and are very slow to sprout. There are various pretreatment methods, but the simplest is to soak the seeds for 24-48 hours in warm to the touch water, just prior to planting. Optionally, seeds can be lightly scarified with sand paper to provide some permeation on the seed coat. Once pretreated, plant seeds 1/2-1″ deep in moist, sterile soil. Keep soil temperature consistent at 70-85F, with some day/variation in this range. Cool soils will significantly delay seed germination time if not inhibit germination altogether. Standard room temperature can be too cool for proper germination.
