Tanacetum Parthenium 'Selma Star'

Supplied by a collecter of these seldom-seen-or-grown old plants, this ancient cottage garden variety has cartwheel-like creamy-white flowers, with short spokes and a disproportionally large 'hub'. Flowering in profusion from May until August, this rare and quite distinct flower is superficially like Malmesbury, but has the added bonus of a shallow central dome of crested petals.
