Ruby is a pink-fleshed grapefruit with some blush to the peel. It is the predominant variety in Florida and Texas, and has the same excellent eating quality as Marsh Seedless. The Florida-grown fruit is thin skinned with excellent flavour and masses of juice: as near irresistible as a grapefruit can get! Also known as Ruby Red, Tropical Ruby, Redblush or, in Southern Africa, Rose.
As Florida is a moist tropical environment, the fruit is often affected by melanose, a fungal disease. This is manifest as tiny black spots on the skin, and is entirely cosmetic, with no affect on internal quality. Supermarkets have, over the years, demanded Florida Pink to be as clean as possible, but needn’t have gone so far!
Origin: Ruby originated from Pink Marsh (aka Thompson), which itself came from a chance sport on a Marsh Seedless tree, hence the similarity with Marsh Seedless in all but colour. Ruby was discovered in Texas and released as a variety in 1934.
Grown in: Florida, Texas, South Africa, Swaziland, Israel. In new plantings, Ruby is being superseded by more modern red-pigmented varieties, such as Star Ruby and Flame.
