Many Lobelias need lots of water, but not this lovely red Mexican lobelia. Though very frost tender, Mexican lobelia comes back from the root stock in the spring. This lobelia can spread aggressively, so it is not recommended for someone looking for a low maintenance plant.

PADG Notes: After frost damage, scraggly branches are pruned back to about three feet for a neater appearance. When danger of frost is gone, the plant is pruned to the ground. Mexican lobelia has spread aggressively in the garden and needs regular root pruning to keep under control.  

Warning: Lobelia may cause serious illness or death if eaten. If ingested, immediately call the Poison Control Center or your doctor. In addition, the juice or sap of the plant can cause a skin rash or irritation. Wash the affected area of skin with soap and water as soon as possible after contact.
