The typical species is the Common Daisy of British and European pastures, but it has given rise to many fine garden varieties - all with double flowers. They are all easily grown in moist rich soil, and a great trade is done in the plants from March to June every year, and even then the flower heads, especially if long-stalked, will sell fairly well as "cut". From 70,000 to 80,000 plants can be grown on an acre of ground, and at only ¼d. each that represents a turnover of about £80 per acre. The only cultivation after planting in summer or early autumn is to keep the soil free from weeds, and this is best done by using a small hoe between the plants. Some of the best varieties are Diana, red; Goliath, rose and white; La Fiancee, pure white; Pink Beauty, pink; and Rob Roy, bright crimson. The "Hen and Chickens" Daisy has a cluster of small flower heads round a larger central one. A variety known as Ma Paquerette on the Continent has flower heads 3-4 in. across, and comes fairly true from seeds like many of the other varieties.
