Amaranthus blitoides aka Mat Amaranth

Taxonomy

Amaranthus blitoides, also known as prostrate pigweed, mat amaranth, or matweed, is a glabrous annual plant species that usually grows up to 0.6 m, but may reach up to 1 m in height. It flowers in the summer to fall and is believed to have been a native of the central and possibly eastern United States, but has since naturalized in almost all of temperate North America, as well as South America and Eurasia. However, some authorities list it as an invasive species that can be problematic in lawns and gardens. The plant grows in a circular form with low-growing stems coming from a central spot, resembling a spider web. The radial stems are reddish-purple and can grow over a foot long, while the leaves are about a half inch long and oval-shaped. The flowers are reddish-green but not significant, producing seeds that look like small black sand grains. Mat Amaranth is a super rare houseplant that requires regular watering and long-lasting, direct light less than a foot from a window. The plant prefers well-draining soil, and repotting each time it doubles in size may eliminate the need for added fertilizers.

Common names

Mat Amaranth, Matweed, Matweed Amaranth

How to care for Mat Amaranth

Difficulty

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

Water

Mat Amaranth should be watered regularly, allowing the soil to dry out between waterings.

Soil

Mat Amaranth 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

Mat Amaranth requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Mat Amaranth will be sure to bring you many years of beauty and enjoyment.

Toxicity

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

Fertilizer

The Mat Amaranth should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Region of origin

Mat Amaranth’s native range is N. America - Washington to Utah and Mexico, east to Maine and New Jersey.
