If you're after Pompom dahlias then Cherub is one for you. Very tightly packed petals that form perfect 5cm balls. Short growing at around 80cm so a good choice for a large container or towards the front of a border, is probably not a good choice for cutting as the stems are a bit short. Barry calls it a large Pom.

Young dahlia plants are shipped in late April/Early May, when you receive them they will need growing on inside until the end of May at which time they can be planted outside.
