False Hemp Datisca cannabina
ABOUT
The plant known as false hemp has a striking and somewhat unusual appearance that draws visual comparisons to true hemp, although it is not related. This plant typically features pinnate leaves that grow in a lush green display, reminiscent of a fern or feathery foliage. The leaves are composed of several leaflets, which are elongated and organized on either side of a central stem. The overall foliage presentation is robust and somewhat bushy, contributing to a dense and green aspect. During the flowering phase, false hemp produces small and inconspicuous flowers. These flowers are usually arranged in spikes and can be found in shades of green or yellow, providing a subtlety that contrasts with the more vibrant foliage. There is a distinct sexual expression in this plant where male and female flowers grow on separate plants, known as dioecy. The male flowers are more structured in their arrangement, while the female flowers tend to be looser and less defined. After the flowering period, the plant produces clusters of fruits that follow the same subdued color palette, blending with the plant's overall color scheme. These characteristics contribute to a rustic charm that makes false hemp a unique addition to any garden or natural space where it can grow freely. Despite its name and visual similarities to true hemp, it should be noted that it bears no actual relation to the cannabis plant.

ToxicityTo humans
False hemp (Datisca cannabina) is generally not well-documented for its effects on human health. However, due to the lack of specific information regarding its toxicity to humans, it is prudent to handle it with care and to avoid ingesting any part of the plant. If a plant is not well-studied for its effects on humans, it is possible that it could contain compounds that are irritating or potentially harmful. If you suspect poisoning from any plant, including false hemp, it is important to seek medical attention immediately.
To pets
False hemp (Datisca cannabina) has not been specifically reported to be toxic to pets. However, due to the lack of detailed research on its effects on pets, caution is advised. Pet owners should prevent their animals from ingesting parts of this or any unknown plants. If a pet ingests any part of this plant and shows signs of distress such as vomiting, diarrhea, drooling, or changes in behavior, it is important to consult a veterinarian as soon as possible.

WaterFalse hemp should be watered deeply to encourage a strong root system, which usually means applying about 1-2 gallons of water per plant every week during the active growing season. During periods of drought or extreme heat, the frequency of watering may need to increase to twice a week. It is important to avoid overwatering as this can lead to root rot, so allow the soil to dry slightly between waterings. In the winter, reduce watering significantly since the plant requires less moisture when dormant.
LightFalse hemp thrives in full sunlight, so it is best to plant it in a spot where it can receive at least 6 to 8 hours of direct sunlight each day. Although it can tolerate some light shade, too much shade can result in leggy growth and fewer flowers. The ideal location is an open area away from the shade of buildings or trees.
TemperatureFalse hemp grows best within a temperature range of 50°F to 90°F and can survive minimum temperatures down to about 25°F. Ideal growing conditions are warm days and cooler nights that fall within the aforementioned temperature range. Avoid planting it in locations where temperatures may drop below 25°F without protection, as frost can damage or kill the plant.
PruningFalse hemp should be pruned to maintain shape and encourage bushier growth. Prune in the late winter or early spring before new growth begins. Cut back old stems to improve air circulation and reduce the risk of disease. Occasionally, it might be necessary to remove dead or damaged branches throughout the year.
CleaningNot needed
SoilFalse hemp (Datisca cannabina) thrives in well-draining, loamy soil; a blend of garden soil with perlite and peat should be ideal. Keep soil pH slightly acidic to neutral, around 6.0 to 7.0.
RepottingFalse hemp should be repotted every 2-3 years to avoid becoming root-bound and to replenish its nutrients.
Humidity & MistingFalse hemp prefers moderate humidity levels, but is relatively adaptable to different humidity conditions as long as it is not too dry.
Suitable locationsIndoor
Ensure bright, indirect light and room to grow.
Outdoor
Plant in full sun to partial shade; protect from strong winds.

Life cycleDatisca cannabina, also known as false hemp, starts its life cycle with seed germination, typically in spring with suitable light, temperature, and moisture conditions. The seedlings grow and develop into robust, herbaceous perennial plants, which can reach 2 to 3 meters in height. The plant develops compound leaves and as it matures, it forms separate male and female flowers on different plants, exhibiting dioecious characteristics. After pollination, usually facilitated by the wind due to its dioecious nature, the female plants produce fruit that takes the form of a small, dry schizocarp containing seeds. These seeds are then dispersed by various mechanisms including wind and animals, allowing the plant to colonize new areas. The false hemp enters a period of dormancy during the winter months, dying back to the rhizome to conserve energy before re-emerging in the following spring to repeat the cycle.
PropogationPropogation time
Spring to early summer
The most common method of propagation for Datisca cannabina, also known as false hemp, is through seeds. To achieve the best results, seeds should be sown in a cold frame as soon as they are ripe. Typically, this would be in late summer to early fall, corresponding to the time when the seeds naturally mature and drop from the plant. Sowing the seeds in well-drained soil and lightly covering them with soil ensures optimal conditions for germination. Seedlings need to be kept moist but not waterlogged and should be allowed to grow until they are strong enough to handle being transplanted. Once they have developed several true leaves and are hardy enough, they can be moved to individual pots or directly to their final location in the garden during the spring following sowing, allowing them to establish a robust root system before the growing season.
