Stunning, strong yellow flowers with contrasting purple centres. Not one for the faint hearted but very effective with blue flowers. Drained soil in sun, 1m.
'Cotswold Queen' is one of the more robust forms from the Cotswold Series of mulleins that will generally survive the winter with no trouble as long as your soil is reasonably well drained.
Masses of flower in early to mid summer on strong stems from rosettes of greyish green leaves. If you cut out each flower stem as it goes over you can encourage more stems later though they won't be so tall.
