Citrullus colocynthis aka Bitter Apple

Taxonomy

Citrullus colocynthis, also known as Abu Jahl's melon, bitter apple, bitter cucumber, egusi, vine of Sodom, or wild gourd, is a desert viney plant native to the Mediterranean Basin and Asia, especially Turkey and Nubia. Resembling a watermelon vine, it bears small, hard fruits with a diameter of 5 to 10 cm and an extremely bitter taste. The calyx encloses the yellow-green fruit, which turns marble yellow with stripes when mature. The seeds of colocynth have been used as a food source in areas of the Sahara since ancient times, although they must be heated to become edible. Colocynth is an invasive plant in the Northern Territory, Western Australia, and Victoria. As a houseplant, colocynth is super rare and requires regular watering to thrive. It prefers long-lasting, direct light and should be placed less than 1 foot from a window. Well-draining soil is best, and the plant does not require added fertilizers if it is repotted each time it doubles in size. The plant was originally classified as Colocynthis citrullus.

How to care for Bitter Apple

Difficulty

Bitter Apple presents a moderate level of care, which allows plant enthusiasts with some experience to expand their skills and knowledge.

Water

Bitter Apple should be watered regularly, allowing the soil to dry out between waterings.

Soil

Bitter Apple loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Bitter Apple thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Vine Of Sodom.

Dormancy

During the wintertime, it's common for Bitter Apple to go dormant and their growth may slow down, so waterings should be spaced out more.

Toxicity

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.

Fertilizer

Repotting the Bitter Apple is necessary either when it has doubled in size or once every year, whichever happens first. With fresh potting soil replenished annually, the plant will receive all the necessary nutrients, rendering the use of fertilizer unnecessary. Keep in mind that the source of a plant's energy is the sun, not fertilizer.
