"Here Comes the Sun" is this shrub's anthem

Spirea is a genus that includes around 100 shrubs. These hardy plants have lance shaped green leaves, up to 10cm in length, usually with a toothed edged and have short stalks. The small flowers grow together in a dense spiked cluster. They're either white, pink, red, yellow or purple. Native Americans made a medicinal herbal tea from this plant, however consumption of this plant can be fatal so it's really not advisable! It works well in a rockery and it can also be grown as a hedge. Spirea need moist and fertile soil and plenty of sunshine. They can be affected by powdery mildew and attack from insects and aphids.
