what flowers grow in clusters
Axillary - flowers or clusters of flowers arise at the junction of the stem or axis and the leaf, as in Catharanthus roseus (periwinkle), Callicarpa americana (beautyberry), and Hibiscus rosa-sinensis (hibiscus).
(Syringa x 'Declaration') Star-shaped reddish purple flowers appear in large dramatic clusters in early spring. The scent is spicy sweetâthe essence of spring. The deciduous shrub reaches 6 to 8 feet tall and 5 to 6 feet wide; it takes full sun, or light shade in the hottest climates. Most lilacs bloom best in regions with winter chill (Sunset climate zones A1âA3; 1â11, 14â16).
