Description of the plant
This tropical climbing vine will twist you around!
It gets its sweet names of Corkscrew Flower, Snail Bean or Snail Vine from its flowers that twist in a spiral like snail shells. It has a fragrant, abundant and constantly renewed flowering.
It is easy to grow and can withstand light frosts. It grows very quickly, and in the middle of summer can grow 30 cm a day! Its flowers give rise to long pods whose seeds are edible.
Thanks, to its excellent hardiness, -6°C, this tropical vine can be adapted to many European gardens.
Unique, you can't get enough of it!
Also known as : Cochliasanthus, Snail vine, snail creeper, Snailflower or Snail bean

Growing tips
Repotting
When you receive your plant, repot it in a pot slightly larger than the bucket, which must be well pierced. Avoid pot covers which prevent residual water from draining away and encourage fungal diseases. Choose a fine potting soil, ideally with added perlite or sand to lighten the substrate (do not use garden soil or acidic soil such as heather). Then plan two repottings per year (spring and autumn), gradually increasing the size of the pot and adapting it to the size of the root network (the roots must have room, but not too much as the plant must be able to dry out its substrate between waterings). This avoids having to add fertilizer, which always risks burning the fragile roots of the plants and making the plant wither as soon as the fertilizer is stopped.
Watering
Copious watering: when watering, the entire root ball should be wet, then wait for the substrate to dry on the surface before watering again. These plants are greedy in water, but you should not drown the roots either. Always water at the base of the plant, and do not mist it, because stagnant water in the armpit of the leaves favors cryptogamic diseases. If your atmosphere is too dry, put bowls of water nearby (above radiators for example), so that evaporation humidifies the air.
Pruning
This plant is very easy to prune, which will make it branch out.
Fertilizer
Our plants are grown naturally, without chemical fertilizers, so we advise you to repot them regularly (twice a year) rather than adding fertilizer.
In case of pest attack
If your plants are under attack by aphids or other pests, the best way to control them is by hand. Change their soil, remove as many undesirables as possible by hand and then shower your plants with a strong stream of water to eliminate any eggs that may be present. Spray them (insist on the underside of the leaves) with liquid black soap diluted in water. Repeat the operation several times at a few days interval. Take them outside in good weather, rain, sun and wind will kill most of the aggressors!
