They brighten up any garden and home.
The Mexican Sunflower has attracted several different butterflies.
Gray Hairstreak butterfly
This photo shows two separate plants. They grow tall and bushy. The branches are fragile. The plant will need some support. In windy conditions, the branches will break or the whole plant will fall over (from experience).
This beautiful flowering plant came from the seed packet, Bring home the butterflies, Botanical Interests. They re-seed well in my garden.
Orange Sulphur Butterfly
