Passiflora citrina

Japanese name: パッシフロラ キトリナ
Scientific name: Passiflora citrina

[Overview]
An evergreen woody vine.
The vines grow to 5–6 m and become woody.
The stems and leaves bear fine pale brown to white hairs.
Leaves are simple and alternate, cut in a feather-like (arrow-feather) pattern, with entire margins.
There are tendrils at the base of the leaves, with which the plant clings to other objects.
Racemes arising from the leaf axils bear flowers about 3.5–5.5 cm across.
The flowers have 5 sepals and 5 petals each, all yellow and of the same shape and size, so the flower looks as if it has 10 petals.
Inside the flower there is a yellow corona; 5 radiating stamens and 3 stigmas protrude out of the flower.
The fruit is a berry.

[Cultivation]
Propagate by cuttings.
To overwinter, keep it at 5°C or above, and bring it into a bright place indoors in winter.
It prefers sunny, well-drained soil.
Be careful of overwatering; from spring to autumn, water thoroughly when the soil surface dries, and keep it on the dry side in winter.
If it dries out during the flowering period, buds and flowers may drop.
From spring to autumn, apply slow-release chemical fertilizer once every 1–2 months.
The vines grow vigorously during the growing season, so to keep them from tangling, it is good to train them and prune overgrown branches once every 1–2 weeks.
Pests and diseases include seedling damping-off, aphids and scale insects.
