Glyceria maxima aka Reed Sweet Grass

Taxonomy

Genus Glyceria Family Poaceae Order Poales Class Liliopsida Phylum Tracheophyta
Glyceria maxima, also known as great manna grass, reed mannagrass, reed sweet-grass, and greater sweet-grass, is a rhizomatous perennial grass native to Europe and Western Siberia. It thrives in wet areas such as riverbanks and ponds, but it is considered invasive and a noxious weed outside of its native range. This aquatic plant is strong-growing, reaching up to 1m in height, with narrow, strap-shaped leaves that are initially dark green but turn pink in spring. In late summer, it produces purplish-green flowering panicles. Reed Mannagrass, a rare houseplant, poses a fun challenge to grow and requires regular watering. It thrives in long-lasting, direct light and should be placed within 1 foot of a window. Well-draining soil is recommended, and gentle, organic fertilizer can be applied during the peak growing season. Belonging to the Glyceria genus, Reed Mannagrass is native to Europe and Northwestern China.

How to care for Reed Sweet Grass

Water

Reed Sweet Grass should be watered regularly, allowing the soil to dry out between waterings.

Soil

Reed Sweet Grass 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

Reed Sweet Grass 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 Reed Sweet Grass 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.

Growth-pattern

The Reed Sweet Grass is clumping in nature, with new growth originating from the soil in close proximity to the original plant.
