Agapanthus are divided into two groups
1 Evergreen group (Intermedius type, for example, variety ‘Donau’) which you can keep over the winter as a container plant indoors;

- ‘Donau’ – light blue
- ‘Albus’ – white
- ‘Kobalt’ (a small flowering variety – 30 – 50 cm high) – blue
- ‘Intermedius’ – dark blue
