Crocus 'Ruby Giant' Bulbs – Purple with Frosty White Interior, Species Crocus, Fall Planting

Crocus 'Ruby Giant' is a sturdy, extra-early Species Crocus from Holland with broad, rich purple petals — red-violet on the outside with frosty white highlights on the interior that create a beautiful bicolor effect when the blooms open wide on sunny days. Like all crocus, Ruby Giant closes on cloudy days and opens fully in sunshine, giving it a dynamic, responsive presence in the garden. A strong naturalizer with reliable perennial performance, it's an excellent choice for bedding, rock gardens, border fronts, and lawn tapestries.

Planting & Care

Plant in tight clusters or naturalistic drifts in well-drained soil, pointed tip up, in September or October. To deter mice and squirrels, lay chicken wire over the planting area before covering with soil. If growing in lawn, avoid mowing until foliage has fully died back in late spring. Leave undisturbed for several years for the best naturalized display.
