It really bugs me that they've put this in the database as Zebra. I've often wondered if it might have something to do with the Kasperek's Zebra Gardens nursery.. perhaps not.. I personally prefer the Royal Hort nomenclature as pallida 'Aurea Variegata', as it tells you exactly what it is: yellow and variegated. Ok… getting off my soapbox now..
