Looking to add a tropical flair to the garden without all the work? Grow deceptively hardy perennial hibiscus. Hallberd-leaf mallow (H. laevis) and swamp rose mallow (H. moscheutos subsp. palustris) are native to southern and eastern North America.

To grow hibiscus without rust follow a few simple tips:

1. Air circulation: do not overcrowd your plants.

2. Soil: hibiscus likes rich, moist soil. Site appropriately.

3. Water: never use sprinklers on plants in the mallow family.

4. Weeds: remove weeds like Wild Mallow from your garden. Other mallow family plants can harbor and spread fungal diseases.
