What it's good for, and what it isn't

A cormous perennial that sends stiff, upright stems out of a tuft of grassy leaves, with purple, pink or white bottlebrush spikes that open from the top down in midsummer. Butterflies and bees love it, it is excellent as a cut or dried flower, and it takes heat well. Plant it in sun in soil that stays fresh yet drains freely: once established it tolerates shorter dry spells, but it needs watering in prolonged drought and rots in winter wet.

Watch out for

The corms rot in wet, compacted soil over winter, in which case the plant simply fails to emerge in spring. Voles and other rodents readily eat the corms, and slugs graze the young shoots in spring. Stems of taller forms may flop in rich soil or with too little sun. In the dry, hot summers of Central Europe the lower leaves wither and flowering is cut short without watering.
