Black Flowering Fountain Grass- Pennisetum alopecuroides- "Moudry" This specimin blooms in mid to late fall and loves the sun. It grows in consistent soil moisture but prefers well drained soil. It grows to approximately 3 feet with 12 to 18 inch spacing. This ornamental grass is hardy zones 6 to 9. Special note: If the normal pruning methods do not provide seed heads of around 6 to 8 inches in length try burning the plant to the ground in early spring (in Southern Massachusetts around March 15 th, and provide minimal amounts of moisture and a 10-10-10 furtilizer. Beautiful ornamental and easy to care for. Dave Wilson, Massachusetts
