Roscoea 'Harvington Raw Silk' AGM


Add to wishlist Remove from wishlist
Another gorgeous introduction from Hugh Nunn whose nursery is in the village of Harvington. This has obvious Roscoea humeana in its parentage which contributes large flowers well-displayed on a stout plant. A light cream is the flower color and ours were initially but these same plants have become more yellow. Which is not a bad thing but curious. Even though this in the Ginger Family, it is not suitable for the Southeast as it likes cool nights.
