Cautleya gracilis var. robusta ‘Purple Emperor’

A new form, named by Nick Macer and Paul Barney, similar to 'Tenzing's Gold' but better, with superb deep maroon undersides to the leaves. Rich yellow flowers from red tinted bracts in late summer on stems to 50cm. Enjoys a semi-shade position in good free draining soil that doesn't get too dry. Mulch over in winter if you live on Ben Nevis, but otherwise hardy if not waterlogged in winter.
