At least two striped dahlias appear to have been sold under the name ‘Zebra’.  Charles Turner of the Royal Nursery, Windsor, advertised Yale’s ‘Zebra’ for sale in The Gardeners Chronicle, describing it as a fancy variety, maroon striped with orange.  [Gard. Chron. 1847].  The Floricultural Cabinet provided a list of new dahlias offered to the public in 1853 and described ‘Zebra’ as ‘light, with brown stripes; well up and good outline.’  [FC p.37/1853].  This later cultivar is likely to be the catalogue plant.  Among prize getters listed in The Gardeners Chronicle was Keynes’ ‘Zebra’, a fancy variety.  [Gard. Chron. 1853].  It was still being offered for sale by Keynes’ Nursery in 1860.  [Gard. Chron. 1860].
