Owing perhaps largely to our greater intercourse with continental nations the once much-despised Dandelion (Taraxacum Dens-leonis) is now a crop worthy of the attention of some market gardeners. Indeed it has been sent to market for many years past by one or two who developed a connection for it, although one cannot say that it has been "cultivated" as a crop in the ordinary sense of the term. The plants are allowed to grow just wherever they like, and when large enough for sale, are sliced off with the hoe, washed, and packed in baskets for market, where they realize from 9d. to 1s. 6d. per half-bushel, and sometimes more. The leaves, green or blanched, are appreciated as a salad. Besides the common variety, there are now one or two improved strains.
