Choose a sunny location, where soil is well-drained. Space plants as listed:
‘Hot Lips’: 2 to 3 feet apart. Zones 7-10.
'Pink Parfait’: 2 to 21/2 feet apart. Zones 7-10.
‘Sissinghurst’: 2 to 21/2 feet apart. Zones 5 (with protection)-9.
‘Tukana Scarlet’: 2 to 3 feet apart. Zones 6-9.
Water plants during extended periods of drought. If necessary, plants may be divided in spring. In areas north of hardiness zones, dig up plants in the fall and winter over in a frost-free cold frame.
