Perennial Maltese Cross are grown from seeds. They can be directly seeded into your flower garden, or seeded indoors six to eight weeks before the last frost in your area. Sow seeds early in the season, and cover lightly with 1/8″ of fine garden or potting soil.
Maltese Cross seeds germinate in 10 – 15 days. We recommend using a heated germination mat.
The ideal final plant spacing is 12″ -15″ apart. Thin or transplant seedlings, if needed, when they reach 2″. The plants tolerate a little crowding.
Established plants can also be propagated by plant division of the rootball. Separate and replant in spring or late fall.
