Stratify the seeds in the fridge before you sow them to make the germination easier. Place the closed packet of seeds approx. 4 - 6 weeks in the fridge. Remove the seeds from the fridge and let them get to roomtemperature before you sow them. Sow indoors in trays filled with moist pottingsoil from March on. Sow thinly and cover the seeds with a thin layer of soil. Keept the temperature as even as possible between 20 - 25 °C. Don't let the temperature drop during the night. Use a warm room or propagator to sow in. Cover the trays with a lid or some clingfilm tot keep the moisture inside. Keep moist, but not to wet to avoid the molding of the seeds. Remove the lid or clingfilm when the seedlings emerge. Transplant the seedlings to seperate pots when they're large enough to handle. Put them away a bit cooler (18 - 20 °C).
Harden the seedlings of in the beginning of May by putting them outside during the day. For approx. 10 - 14 days. Put the young plants outside from the middle of May on a sunny spot with some half shade and good draining soil. Keep the plants 30 - 45 cm apart. Give the plants a sturdy support to prevent the stems from breaking. Deadhead often.
Sow outdoors from half May, when there's no longer any danger of nightfrosts. Sow shallow and thinly and cover the seeds with a thin layer of soil. Keep moist and weedfree. Thin the seedlings, when they're large enough to handle to 30 - 45 cm apart. Give them a sunny plot with some half shade and well draining soil. Give the plants a sturdy support and deadhead them often. These plants can be divided in the Spring following on the sowing year by digging up the roots and replanting them. Deadhead often to prevent the plants from selfsowing. These seeds are often eaten by birds (Finches). The leaves are eaten by rabbits.
