Standard tree forms of Hibiscus are an impressive and rare form, with big blousy flowers covering every branch in the height of summer. August to October flowering. 

'White Chiffon' is even more unique with its double bloom. While 'Pink Giant, and 'Ultamarine' are deeply coloured and intricate blooms. 

This tree hollyhock is ideal towards the back of a sheltered, sunny border. Vigorous and easy-to-grow.
