Dwarf compact strain with grey foliage and deep purple flowers - 45cm. Plant seeds no deeper than 6 mm (1/4 inch). Seeds take from 14 to 28 days to germinate. When large enough to handle, plant seedlings on and transfer gradually outside after all danger of frost is past. Please note Lavender is slow to germinate and is a slow grower once established. Please Note - Lavender seeds are by nature ' low and slow' germinators and one of the harder varieties to grow from seed. Lavender seeds have a short shelf life (these are the freshest possible), and therefore the germination rate (how many seeds out of 100 come up) is usually pretty low. They can also take a long time to sprout (two weeks or more) and this increases the risk of fungal problems, with the potential for seed to rot if insufficient temperature is provided. We offer a large quantity of seed to compensate for these natural problems, from which with care you should generate more than enough plants to populate the largest garden. Although English lavender can live 20 to 30 years, it becomes untidy after a few years, so trim plants back in spring and again in early fall.
