66. Senecio Halimifolius ; Succulent-leaved Groundsel. 

 Corollas radiant ; leaves obovate, fleshy, toothed ; stem 

 shrubby. This, with the other Cape species, are too ten- 

 der to live in the open air of an English winter, yet only 

 require protection from hard frosts : and if kept in pots, and 

 placed either under a frame in winter, or in a common green- 

 house with other hardy kinds of plants, which require a large 

 share of air in mild weather, will survive the winter. They 

 are all easily propagated by seeds or cuttings, but the last 

 method is preferred for the sake of expedition. If the cut- 

 tings are planted in a shady border during summer, they will 

 soon take root, and should be taken up with balls of earth 

 to their roots, and planted in separate pots filled with good 

 kitchen-garden earth, then replaced in the shade to take root, 

 and afterwards removed to an open situation till winter, when 

 they should be sheltered, and treated like other hardy green- 

 house plants. If propagated by seeds, they should be sown 

 on a bed of fresh earth, exposed only to the morning sun,' till 

 the beginning of April; moisten the ground in dry weather, to 

 forward their vegetation. When the plants appear, weed them 

 till they are fit to remove, and then treat them in the same 

 manner as those raised from cuttings.
