Aquilegia has many common names such as columbine or grannies nightcap/bonnet. They are clump forming perennials which are grown for their rosettes of deeply lobed blue-green leaves. They have distinctive bell-shaped flowers with colourful, spurred petals which come in many colours from purple to yellow. They like to grow amongst other perennials or shrubs for a little support and dapple shade. They can tolerate all soils as well as drought but do not like water logging. The seeds and roots are poisonous. They can be a little short lived but freely reproduce themselves from seeds, so you should always have them.
