Large, chalice-shaped, deep pink-violet-purple blooms are packed together, and open in dense umbels in June and July. The large spherical heads of flowers, all with pointed petals, produce the famed ‘exploding firework’ effect. In the wild these plants grow in Xinjiang, also in Afghanistan, Tajikistan, Uzbekistan, Kyrgyzstan, and Tajikistan..... gosh what a lot of stans!!
Sow seeds at any time, covering them very thinly with compost or grit, keeping the seed pot in a cool, well-lit spot outdoors. Artificial heat is not needed and can prevent germination so be very patient as many species will only germinate in the spring after chilling or freezing in the moist seed pot in the winter. Grow on individual seedlings in small pots until of sufficient size to be potted on or planted out into the open ground.
