The flowers  are good for cutting and are borne above the foliage on long strong stems . The foliage is lacy and fern like and is aromatic ,  and forms an attractive clump of base foliage.

It is not invasive, and will bloom the first year.

It is best grown in lean dry to medium well drained soils,  forms and and will tolerate poorer soils so long as the drainage is good. It doesnt like moist rich soils and will not thrive.  Plants can tolerate humid hot conditions in summer and can tolerate some drought.

It is reportedly resistant to deer and to rabbits.

Sowing advice

Sow Spring to Midsummer or in the Autumn.
Sow the seeds on the surface of lightly firmed, moist seed compost in pots or trays. Cover seed with only a light sprinkling of compost  as light aids germination. Water from the base of the tray, Keep in a warm place,  ideally at 15 to 20°C. Keep  moist but do not waterlog. Germination shoudl take between  5 to 10 days.
transplant  each seedling once it has its first set of true leaves and put into 7.5cm  pots containing free-draining compost  until large enough to plant outside. Plant out in well drained soil in full sun and light lean  soil which aids formation of strong stems that dont flop.
