Crocus 'Ruby Giant'
An outstanding and aptly named variety, 'Ruby Giant' is a cultivar of Crocus tommasinianus and is celebrated for its larger-than-average flowers and rich, vibrant colouring. The blooms are a stunning shade of deep, iridescent reddish-purple or amethyst, which seems to glow in the low spring sunlight. The flowers open wide on sunny days to reveal a bright orange stigma at their heart. 'Ruby Giant' is one of the earliest crocuses to flower, often pushing through snow to provide a welcome splash of intense colour. It is exceptionally vigorous and an excellent naturaliser, quickly multiplying to form substantial, beautiful drifts. It is more resistant to squirrel damage than many other crocus types, making it a reliable choice for gardeners. Its slender, grass-like foliage appears with the flowers, creating a neat and attractive clump.
