To
genus Cyclanthera (family Cucurbitaceae) belong about
25-30 species origin to Americas (from southern USA to Argentina). They all are
(sub-)tropical climbers. At least 3 species creates edible delicious vegetable
fruits. I am describing below my experiences with growing these 3 species
(4 taxons including botanical varieties). In northern temperate climates all these 3
edible species can be sown immediately outside in the first half of May.

Small Achoccha (Cyclanthera achocchilla) fruits |
Achoccha,
Achocha, Caigua, Caihua - (Cyclanthera
pedata) this is a creeper up to 5m (16ft) long, which is used in Amazonian / Andean
medicine and cultivated as a vegetable. The plant originates from the Andes,
but it does not exist in the wild state - it can be found only in the tropics of
the old and new world and in cultivation (or rarely escaped). Its fruits are edible
(young - whole raw or cooked, and older - without seeds - boiled) and young
boiled leaves. There are two varieties: var. pedata and var. edulis.
They differ mainly in the size of the fruit. Variety var. edulis
creates a longitudinal, asymmetrical ( a little resembling a shoe - hence the
English names "slipper gourd", "lady's slipper"), hollow
and often (softly) spiky berries about 15-20 cm (=6-8inch) long, while the fruits of the var.
pedata are similar but reach only about half of this size. The
advantage var. pedata often begins to bloom earlier and yields greater yield
than var. edulis (from which you could not collect anything because late blooms
if you grow it in cold temperate area). Seeds are black and angular about 1 cm
(=0,4inch) long (var. pedata) or 1.5 cm(=0,6inch) (var. edulis). Variety
var. pedata usually very well fruited in my experiences, and
without larger efforts, gives a large yield (several dozen fruits from the
plant). It is also resistant to diseases (my plants attacked only viral
disease). In contrast, var. edulis, which usually blooms on a short day, is
unprofitable in northern latitudes. The taste of fruits is specific: the raw
ones resemble cucumber, but after cooking are completely different, specific
(their aroma is sometimes describes as "carbolic"). But the most of
people like it. As already mentioned, it
is also a medicinal plant - for example, seeds are used for lowering blood
pressure (but be careful, because they are probably also poisonous).
Cyclanthera pedata var. pedata
|
The leaves of this species are palmately compound |
|
The male and female flowers |
|
It is quite large climber |
|
Although the fruits of this variety are not large it gives good crop in northern temperate areas |
Cyclanthera pedata var. edulis
|
This variety creates very large fruits |
|
... but gives small crop because it is short-day flowering |
Apart
from this species, there are two other related plants with smaller, also edible, very
tasty fruits (they are wild and only rarely cultivated):
Small
Achoccha, Achocchilla (Cyclanthera
achocchilla – other names: C. brachybotrys, C. tomentosa) with small
fruits, covered with soft spines, which do
not explode when ripe. The leaves are triangular or shallowly 3-5-lobed.
Species native to South America (Colombia, Venezuela, Ecuador, Peru and
Bolivia). It is very easy in temperate gardens and yields good crop. It blooms
and fruits well in long-day condition and is day-length insensitive. It creates
very numerous fruits in short time (in about 2,5-4 months).
|
The fruits are small but created abundantly and delicious (raw or cooked) |
|
The leaves of this species are similar to common cucumber |
Exploding Cucumber (Cyclanthera
explodens, syn. C. brachystachia) – the
climber with undivided leaves and exploding (when mature) - scattering seeds,
very small (smaller than in the previous species) edible fruits. The leaves are deeply 3(5)-lobed. It is native to:
South America (Venezuela, Colombia and Equador) and Central America (Guatemala,
El Salvador, Nicaragua and Costa Rica). It is very easy (day-length
insensitive) but does not yields strong due to fruits are very small.
|
This species creates very small fruits which break up when ripe |
|
The leaves are deeply trilobed and fruits are asymmetric |
There exists numerous other wild Cyclanthera species - if you have available the seeds of any of them please write to me.
Thank you! I'm finding seeds for sale that include strikingly different plants all labeled as Cyclanthera pedata. I had to search for a bit before I found your site that described two other Cyclanthera species that are commonly eaten. After reading your descriptions (and viewing your very helpful photos), I think the other species being called Bolivian cucumber/Achocha is actually Cyclanthera achocchilla (or perhaps Fat baby?, (Cyclanthera brachystachya)).
