Antirrhinum Majus Pumilum
Commonly called Snap Dragons. Tom Thumb is a dwarf variety with beautiful bright coloured flowers. Snap Dragons are frost hardy so can be planted in early spring. Snap Dragons should be fertilised often to keep them flowering. 
Snap Dragon seeds should be raised as seedlings. The seeds should be planted on the surface with a light sprinkle of soil as they need light to germinate. They can be grown in the garden or in pots.
Full sun position with only occasional watering.
