Gillenia plants are a genus of hardy perennial shrubs that reach a height of about 1.2 meters (4 feet).
They bloom in the summer when they carry white stellar flowers.
A commonly grown Gillenia plant in the garden is Bowman's Root. Latin names include Gillenia trifoliate and Gillenia stipulata.
Gillenia trifoliata by Campobello Island.
Common Names: Bowman’s root, American Ipecac, Indian Physic.
Life Cycle: Hardy perennial.
Height: 30 to 50 inches (75 to 125 cm).
Native: Northern America.
Growing Region: Zones 4 to 8.
It is best to first sow Bowman's roots in flats. Sow the seed at the beginning of autumn at a depth of 7 mm (1/3 inch). Cover the flat with glass, and sink into a shady part of the garden. Keep the soil moist.
Once Bowman's roots germinate (about three weeks) and sprout, transplant them (late autumn) into their final location.
Gillenia species such should be spaced at about 45 to 60 cm (18 to 24 inches) apart.
They can grow in sunny and partially shaded parts of the garden. Ideally they prefer to have a rich, acidic (pH 5 to 6) woodland soil in which to grow.
Gillenia plants likes to grow in a moist soil so keep well watered. Supply a permanent mulch. Stake taller species.
Once flowering has finished cut back plant stems.
If you require more plants then propagate in the spring or autumn by division.
