At one time a favourite florist's flower, the Ranunculus has fallen greatly out of favour, and there are now few named sorts grown. It is, however, well worth growing for its beauty as a garden flower and also for cutting. A bowl of pure white Ranunculi with the foliage of Heuchera Richardsoni, or some other dark-leaved plant, is a charming thing, and many equal beautiful effects can easily be produced. The florist's Ranunculus was derived from R. asiaticus, and there are flowers of almost all colours among the double varieties which have been raised. A good strain of mixed Ranunculuses will produce many good flowers at a small expense. The principal forms now grown are the Turban or Turkish and the Persian, which are varied in their colours. Those named R. asiaticus superbus are large and showy, if a little coarse to those accustomed to the more refined flowers of the others. They can be grown in an ordinary border well manured, and can be planted from October to February. In planting choose a dry day, and keep the crowns two inches below the surface. Care must be taken to keep the crown up, and to cover this with a little sand after planting. Cover with some litter in winter, and water freely when coming into bloom. Lift when the foliage becomes yellow, and dry off in a cool and airy place, storing the tubers in dry sand.
There are a few other tuberous-rooted species of Ranunculus worth growing in the garden. Of these the best are the double form of the native R. bulbosa which has yellow flowers; R. chærophyllus, yellow; R. monspeliacus, yellow; and R. millefoliatus grandiflorus, the same colour. These are easily grown in the border in ordinary soil.
Romuleas are remarkably pretty little bulbs with Crocus-like flowers, from March to July, and grassy leaves. They require warm, sunny spots on rockwork, and in cold localities should be grown in a frame. They like sandy soil. Among the best and hardiest are R. Bulbocodium, with blue and yellow flowers. The variety pylium is even prettier. Columnæ is pretty with its white flowers. Clusii, lavender, and speciosa, rosy violet, are both pretty. Plant in autumn two inches deep, and protect in winter.
S. canadensis, the only species, is a pretty little plant, known as the Bloodroot, Red Puccoon, or Red Indian Paint, and perfectly hardy. It has white flowers with a yellow centre in April, and the leaves are not fully developed until after the flowers. It likes a rich moist soil, but can be grown in the border. The best form is grandiflora, and the one called multipetala has many narrow petals. There is said to be a pinkish form.
