1 litre sized pot.  Echinacea purpurea Brilliant Star is a hardy herbaceous perennial that produces large pinky-purple flowers on strong stems.  Reaches up to 90 cm tall once established.  The flowers have a golden brown central cone and initially the petals are narrow and greeny-pink then once open they reflex slightly away from the central brown disc.  They are loved by bees and beneficial insects. Winter dormant. Great as a cut flower.  Likes a sunny position in well-drained soil.  NOTE:  Echinacea are starting to head into dormancy as we progress through autumn.
