Know before you buy
Since the Karl Foerster reaches a mature spread of 3 feet, you should space them approximately 2 to 3 feet apart to allow for proper air circulation while still achieving a cohesive, filled-in look.
It is considered a low-maintenance perennial. The primary task is to cut the foliage back to the ground in late winter or very early spring before new growth emerges.
Yes, this variety is hardy in USDA zones 4 through 8. It is a perennial, meaning it will go dormant in the winter and return in the spring.
While it thrives in partial shade to full sun, it performs best with at least some direct sunlight. In deep, full shade, the plant may become floppy and produce fewer plumes.
No, this variety is not considered deer resistant. If you have a high deer population in your area, you may want to protect the plants or consider using a repellent.
The plumes are persistent and provide excellent winter interest, so you can leave them standing throughout the colder months. Simply remove them when you perform your annual spring cleanup.
