A stately, towering perennial, its stalks rise to 7 feet tall or more! Brilliant, yellow-green umbels and thread-like leaves that turn golden in fall make this is a landmark that WILL be noticed! Shelter from high winds, best with some summer water; drought might trigger dormancy.
Only for ornamental use. Despite its common name, this is NOT culinary fennel.
Mature size: 7-8+ feet tall & 2-3 feet wide.
Minimum temperature: 0º F
