Blue vervain tips: Blue Vervein seeds can be sown in spring or autumn. They benefit from cold stratification. For autumn sowings the seed trays can be left outdoors to have their dormancy broken, alternatively sow in a seed tray with a light covering of compost and put in the fridge for around 2 weeks. Then place somewhere warm such as a windowsill or tunnel bench to germinate. Blue vervain needs to be in the dark to germinate, so either keep them in a dark place or cover with a sheet of paper or such. Prick out and pot on before planting outside in late spring/ summer. Wildflowers often take somewhat longer to germinate than vegetables. Typically between 14-28 days, up to 90 days.
