Panicum bulbosum

Panicum bulbosum, commonly known as Panic Grass, is a perennial grass native to parts of Europe and Asia. It features a large spiked inflorescence of golden-brown panicle branches covered with small, light brown spikelets. Growing to a height of 60-90 cm, it prefers damp, wet soil and grows in colonies. Its flowers bloom in July and August, and it is an important element of wet and marshy meadows. The leaves are flat and long with sheaths around the stems, and the stem root of the plant is bulbous. Panic Grass is often used as an ornamental in gardens or along pathways, as it adds a subtle yellowish-brown hue and a wild charm to the landscape.

watering

Panicum bulbosum should be watered moderately, about 1 inch per week throughout the growing season. Avoid overwatering, as this can lead to root rot and other issues. It is a drought-tolerant plant, so allowing soil to dry slightly in between waterings is ideal. Panic grass does prefer more water later in the season when temperatures begin to drop, as well as more regular showers after establishment. During exceptionally hot summer months, increase watering to prevent wilting and keep the soil moist.

sunlight

Panic grass (Panicum bulbosum) typically prefers full sun but can tolerate light shade if needed. It requires 6-8 hours of direct sunlight per day and will typically bloom from late spring to early fall. Plants grown in part shade may not bloom as abundantly as those grown in full sun.

pruning

Panicum bulbosum should be pruned twice a year to promote bushier growth. The first pruning should occur in late spring when it has finished flowering and the second should occur in late summer or early fall. It is best to lightly trim the plant in early spring and then prune again in late summer. When pruning, remove the tallest stems and any dried leaves or flower heads. For best results, try to remove roughly a third of the height of the Panicum bulbosum.
