About the Family

Crocus (Spring Flowering) Family

Cultivation and harvesting of crocuses was first documented on the island of Crete in the Mediterranean. Crocus are native to woodland, scrub and meadows from sea level, to alpine tundra in central and southern Europe, North Africa and the Middle East, on the islands of the Aegean, and across central Asia into western China. The first crocuses seen in the Netherlands, where they are not native, came from Constantinople in the 1560's. A few ended up with Carolus Clusius in the botanical gardens in Leiden. By 1620 some new varieties had been developed that are very similar to ones still being traded today.
