Hardiness Zone 3B
This perennial grows in a backyard garden (Benny's garden) with a southwest exposure in Red Deer, Alberta. The Maltese Cross is an heirloom perennial, popular in Cottage gardens. It is a rugged and easy perennial that grows good in a sunny garden but will tolerate partial shade. The plants form an upright clump of bright green leaves, with taller stems in summer that bear large clusters of scarlet-orange flowers that are excellent for cutting. This year the blooms were larger than in the past . It is best to stake the plant early in the season to prevent flopping.
The height is generally 3 to 4 feet and it is hardy to minus 46 (zones 2-9 USDA).
