A hardy annual up to 1.5 metres high. Sunflowers are gross
feeders and will not thrive in poor soil, therefore they require
a rich soil in an open sunny position and an abundance
of moisture. Before sowing work the soil and incorporate a
complete fertiliser at the rate of 30g per square meter. Sow the
seed directly into the soil and thin the young seedlings.
The plants have multiple flowers, after the petals drop, cut off
the heads and let the seed heads dry. They can then be hung
in bird cages, or in trees to attract birds such as parrots. Also
excellent as a cut flower.
