Tall, branching stems with papery flowers
Clusters of tiny, deep purple blooms
White centers on individual small flowers

Common problems

Crown rot — This occurs when the soil stays too wet for too long, causing the base of the plant to decay.
Aphids — These small insects cluster on new growth and suck sap from the plant.

Growing it

Propagation: seed, division
When to plant: spring
Overwintering: Protect from heavy frost and ensure the soil remains on the drier side during the winter months to prevent rot.
In containers: It grows well in containers as long as you use a very gritty, fast draining potting mix and a pot with large drainage holes.

Seed Sowing

Sow seeds in a well draining seed starting mix.
Keep the tray in a bright, warm location.
Transplant seedlings once they have two sets of true leaves.

Group this plant with others that prefer dry, lean soil to prevent root rot from overwatering.
