These are botanical crocuses, the small kinds that naturalize really well. They are suitable for drifts, lawn, borders, along paths and under shrubs.

Leave the leaf alone after flowering; mow only six weeks later. This mix is essential food for the first bees and bumblebees. The Artist. No two years the same composition. The bulbs come from the Dutch bulb fields. Hand selected for quality and size, and delivered at the right planting time. A larger bulb holds more food, and you see that in the flower: more blooms, and fuller. We offer our 100% Bloom Guarantee.
