Spiked woodrush (Luzula spicata)

Spiked woodrush

A perennial, water-loving grass, spiked woodrush is found in alpine and lowland wetlands, where it grows partly in the shade of other plants. Adapted to a colder climate than many rushes, it grows higher in the mountains in warmer climates, but will grow at near sea level in places like Alaska.

Growth Rate

During its active growing seasons, Spring and Summer, spiked woodrush exhibits moderate growth, gradually expanding its clumps of wiry stems and narrow, slightly curled leaves. The growth tempo corresponds with a measured increase in plant height and seasonal flowering. Fastidious observers might notice the timely emergence of its distinctive, spindle-shaped flower heads, an adaptation synced with its growth rhythm. Interestingly, spiked woodrush's moderate growth rate also conserves resources for hardiness, facilitating survival in colder climates.

Water: Spiked woodrush thrives in cool, moist environments typical of alpine regions and prefers evenly moist soil. It requires weekly watering and features an efficient root system that absorbs water quickly, enhancing its resilience in areas with fluctuating precipitation.

Fertilize: For 'spiked woodrush,' apply a thin layer of mulch or compost annually in spring to retain moisture and enrich nutrients, enhancing growth and soil structure. Use gloves for even distribution, avoiding stems. Timely application during growth spurts maximizes benefits while preserving habitat balance.

Pruning: Spiked woodrush has grass-like leaves in dense tufts with unique spikelet flowers. Prune in early spring before new growth, removing dead leaves for better air circulation. Thin out crowded stems for healthier growth. Use sterilized tools to prevent disease transmission.

Propagation: Spiked woodrush propagates well through division, requiring careful separation of root clumps with sufficient roots and shoots. Replant in well-draining soil, maintaining moisture and light balance. Regular divisions every few years ensure vigor and control spread while managing weed competition.
