Galium tricornutum aka Corn Cleavers

Taxonomy

Galium tricornutum, commonly known as rough corn bedstraw, roughfruit corn bedstraw, and corn cleavers, is a species of flowering plant in the coffee family that is found across most of Europe, northern Africa and southern Asia. It has also been naturalized in Australia, the Canary Islands, Mauritius, Madeira, Réunion, Brazil, Argentina, and scattered parts of North America (mostly California and Oregon). This annual herb forms tangled masses or spreads thin and has stems that are sometimes nearly square in cross-section. The leaves are arranged in whorls of 6 to 8 around the stems and are bordered with prickles. White, thin clusters of flowers appear, followed by pairs of spherical nutlets that hang in the leaf axils. It might be poisonous, but corn cleavers is actually a super rare houseplant that needs regular watering to thrive and direct sunlight. If properly maintained, corn cleavers should not need adding fertilizers as it doubles in size. To get rid of it, you can try to manually pull it, or use a weed wrench, although these will not be effective against weeds with deep underground stems.

How to care for Corn Cleavers

Difficulty

Corn Cleavers is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Corn Cleavers should be watered regularly, allowing the soil to dry out between waterings.

Soil

Corn Cleavers 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

To ensure optimal growth, the Corn Cleavers prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Toxicity

Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.

Fertilizer

The Corn Cleavers should be transferred to a new pot once it has increased in size two-fold, or on an annual basis, whichever occurs earlier. Replacing the soil with fresh potting soil containing all the necessary nutrients, is sufficient enough to support the growth of the plant, thus avoiding the need to use fertilizer. It's important to note that plants derive their energy from the sun and not fertilizer.
