Passiflora holosericea is one of the most profusing flowering Passiflora.
It blooms with beautiful fragrant white flowers with a yellow and reddish brown heart, all summer long.
It is not hardy and difficult to grow as a house plant as it needs lots of light. It is best grown in a heated greenhouse.
Passiflora holosericea is covered with soft hairs all over the plant. The stem is nearly round, 6-9 m long.
Peduncle is 1-3 cm long, with 2 stipules and glands. Leaves are trilobed, shallowly indented, 4.5-16.5 cm long and 3-14 cm wide.
Petioles stand in pairs, 0.5-3 cm long, with 1-3 flowers each. The bract is oblong, up to 1 cm long. The flower is white with a yellow and dark red to brown corona, 3.5-4.5 cm in diameter. The flowers give off a sweet smell.
Fruit is nearly spherical, 1.5-3 cm in diameter. Seeds are 0.5 x 0.3 cm in size.
