Equisetum hyemale
Horsetail
Description
This reed-like plant has dark green, jointed stems that reach 3'-4' tall but will spread. It should receive sun to part shade with regular summer watering. The reed grass can be extremely invasive and is best when used in pots or when confined by a barrier. However, it can be extremely effective as an accent plant. While tolerant of wet conditions, the most successful plantings are those with regular watering and more during summer. It does well in coastal areas. Tall grasses are highly combustible.
