Poa bulbosa aka Bulbous Bluegrass

Poa bulbosa, also known as bulbous bluegrass or bulbous meadow-grass, is a species of grass that is native to Eurasia and North Africa. However, it has been introduced worldwide and is now present practically everywhere. It is a sturdy, hardy, and persistent grass that easily outcompetes other plants and becomes the dominant species in disturbed habitat types, such as overgrazed fields. It is an annual or perennial grass that forms dense clumps up to 60 centimeters tall, with smooth and hollow stems that usually have bulbous sections at their bases. This grass is more likely to have bulbous sections if it is growing in a drier area, and study has indicated that the bulbous sections are mostly water. Although the plant reproduces vegetatively (asexually) most of the time, it has been shown to possess high genetic variability. The inflorescence is a wide cluster of branches bearing green leaflike spikelets with darker bases that contain bulbils. Viable seed is rarely produced, and the plant usually reproduces asexually via its basal bulbous sections and via bulbils. This grass is useful as fodder and a pasture grass in parts of its native region, and many types of animals readily consume it. However, it can be invasive in the Pacific Northwest region and is considered a noxious weed in some areas. To get rid of it, manual weeding and hand pulling are recommended. As a houseplant, bulbous bluegrass needs regular watering and long-lasting, direct light. It prefers soil that is well draining and benefits from gentle, organic fertilizer throughout the peak growing season.
