Common name: Sweet Granadilla
Species: Passiflora ligularis
Hardiness Zones: 9-10
Scarification/Stratification: If your
home is on the low side of 70ºF, your seeds will benefit from bottom heat. Give
warmth from underneath to stimulate early growth, and to help seeds to
germinate. The ideal situation is to maintain the soil temperature at 70ºF. For
this, you use an electric soil warming cable kit, or a heating mat that goes
under your flats, or any other source of heat. With the proper temperature, you
will cut by 2 or 3 the germination time.
seed compost at 1/4″ deep. For Passiflora seeds, instead of using water
you can use a high pulp fruit juice such as passion fruit juice or orange
juice. The acid in these juices will soften the shell and speed up germination.
Keep damp soil, not soaking wet. Keep pot in warm situation 20°C/68°F,
24°C/75°F. Cover the top of the pot with clear plastic so the humidity will
see some tiny plants starting to sprout, slowly open the top of the pot, a
little each day, so that the new seedlings don’t go into shock from the
humidity being lowered too quickly. Germination of Passiflora can occur in
weeks or take several months. If you want to speed up germination, you can use
the bottom heat technique, but it isn’t a must.
The Sweet Granadilla, or Passiflora lingularis, is a common
species ranging from Central Mexico through Central America and Western South
America, through Western Bolivia to South-central Peru. It is naturally adapted
to high rainforests. Naturalized in diverse wet forest, rarely in drier areas.
In its natural range, it is wild and cultivated at elevations of 3,000 to 8,850
feet (900-2,700 meters). At higher altitudes, it flourishes and blooms but will
not fruit. In Hawaii, it finds sufficiently cool temperatures at 3,000 feet.
Vining to 14 feet tall. It climbs by means of clinging tendrils and can be kept
as a container plant. The long tendrils need lots of support for climbing. It
may be grown as a houseplant in a sunny South-facing window. In Hawaii, it is
grown for its fruit and fragrant, ornamental flowers. The flowers are pendent,
sweet in odor, usually 2 to a node, may be 4 inches across, on a 1 1/2-inch
peduncle. The peduncle is bearing 3 leaflike, ovate-oblong and pointed bracts,
1 1/2 inch long and 1 inch wide, faintly toothed. The sepals are greenish
white; the petals pinkish white; the filaments, white, horizontally striped
with purple blue. The fruit is broad-elliptic, 2 to 3 inches long, green with
purple blush on sunny side. The rind is smooth, thin, hard, and brittle
externally, white, and soft on the inside. The pulp is whitish-yellow or
orange, very juicy, sweet, and slightly acidulate. Its leaves are broadly
heart-shaped, pointed at the apex, 3 to 8 inches long, 2 to 6 inches wide,
conspicuously veined, medium green on the upper surface, pale green with a
bloom on the underside. Pruning is a must to keep the vine healthy. Prune off
less vigorous growth and occasionally prune back vigorous growth to promote
flowering. When established, and without care, the passion fruit can easily
overtake other garden plants, shading them from sun. Hardiness zones 9-10,
(-5°C/1°C, 25°F/35°F) in Winter. The vine is intolerant of heat. High
temperatures and dry conditions should be avoided. It will do well over the Winter
in Florida but declines with the onset of hot weather. Prefers sheltered
conditions. Frost tender when young. Provide ideally a temperature of 7-25°C.
It will do best in a loam-based mix with a little peat moss. Thin, volcanic
soils do not discourage the Sweet Granadilla. You may need to water your plants
daily during the hottest summer months. During the Winter the roots should be
kept moist, but as growth will be much slower you will probably only need to
water once a week, depending on growing temperature. Fertilize at least once
every two weeks in the growing season. If their pot is too large or if they
have an unrestricted root run, then the whole plant will simply get bigger and
bigger, but it will refuse to flower and therefore produce the fruits. By
limiting the pot size, you are limiting the ability to grow, and this is seen
as a threat, so the natural mechanism is to produce seed for the next
generation. A suitably sized pot for an adult plant would generally be of 12
inches in diameter.
All seeds will come in a resalable
plastic zip lock bag wrapped in a protectant, so the seeds are not damaged by
shipping machines. All seed packets contain no fillers or other weeds or seeds
mixed in. Most have been harvested by hand & all test at a high germination
All seed counts should be considered estimates as the seeds is
packaged by hand, there is 2-3 more or less in a bag. We do our best to
ensure accuracy and will often add extra seeds. However, all estimates are
Seeds will ship without tracking numbers. Items
will be shipped 1-3 business days of receiving payment. Plants will be shipped
via USPS. Shipping usually takes anywhere from 3-5 days.

Important! Please Read!
All seeds have been test sown to ensure germination.
Please familiarize yourself with growing conditions and instructions for your
seeds before you plant them, as all seeds are different. Basic growing
instructions can be found under each listing.
We Cannot Guarantee how much you will be able
to grow, as too many variables come into play, soil condition, your ability to
garden, weather etc. I guarantee that they arrive as described and are in good
viable condition and the germination rates are accurate.
