Festuca glauca aka Blue Fescue

Taxonomy ID: 6475

Festuca glauca, also known as blue fescue, is a popular ornamental grass in the Poaceae family. This evergreen or semi-evergreen herbaceous perennial boasts icy blue foliage and pale yellow flowers, making it a colorful addition to gardens in USDA plant hardiness zones 4 through 8. While it is drought-tolerant, the super rare houseplant variety of blue fescue requires regular watering and thrives in long-lasting, direct light less than a foot away from a window. When repotting, make sure to use well-draining soil and avoid adding fertilizers unless the plant doubles in size.

How difficult is it to take care of Blue Fescue

With a bit of knowledge and dedication, you can successfully care for Blue Fescue, making it a rewarding choice for those seeking a moderate challenge.

What are the water needs for Blue Fescue

Blue Fescue should be watered regularly, allowing the soil to dry out between waterings.

What is the right soil for Blue Fescue

Blue Fescue 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.

What is the sunlight requirement for Blue Fescue

Blue Fescue 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 Gray Fescue will be sure to bring you many years of beauty and enjoyment.

How to fertilize Blue Fescue

The Blue Fescue 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.

Is Blue Fescue toxic to humans/pets?

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.
