  • Notes

Sunflowers can grow anywhere from 6'-15' tall on top of thick, sturdy stems. They have large, dark green leaves with bright yellow flowers with tender petals that bloom spring to summer. The flowers need direct sunlight and a lot of water.
Planting: 1. Dig a hole 1" less the depth and 2 times the width of the container. 2. Fill hole with water, let soak. 3. Set root ball in hole. 4. Fill hole halfway with native soil and water. 5. Finish back filling hole, build basin and water.
