Hydrangea macrophylla 'Lemon Daddy' offers a superb combination of foliage and flowers. The huge 12in pink or blue flower heads (depending on soil pH) are enhanced by yellow foliage that thrives in heat and humidity, although plants appreciate a little afternoon shade in hot climates and water during dry spells. A sport of 'Big Daddy'. PP 17,660
Hydrangea is a valuable genus of some 100 species of shrubs and vines, which are grown for their large and very showy flower heads. Hydrangeas are at their best in summer and fall—quiet time for most woody plants—and are worth having for that reason alone.
