Sounds as if it wouldn't thrive at all without full sun.
The flower would stretch to try to reach the light for a while. Eventually it would die.

I suggest you experiment with miniature sunflowers. Several companies that sell miniature sunflower seeds have websites. One site advertises a packet of 50 seeds for $3.35. That would give you plenty of plants to test various amounts of light on them.
