Sunflowers

The sunflower (Helianthus annuus) is a living annual plant in the family Asteraceae, with a large flower head (capitulum). The stem of the flower can grow up to 3 metres tall, with a flower head that can be 30 cm wide.

Sunflowers are sun worshipers that grow best in spots that get six to eight hours of direct sun per day. They have long tap roots that need to go several feet into the ground, so sunflower plants prefer loose, well-drained, somewhat alkaline soil with a pH of 6.0 to 7.5.
