until the plant is in as large a pot as can be accommodated. 

 After this another mode of treatment must be adopted. 

 Allow the plant to bloom and go to rest for two or three 

 months, keeping it ratlier dry and cool ; then take it out of 

 the pot, shake the soil from the roots, prune the latter more 

 or less according to their number, repot in a pot as small as 

 will hold the roots, plunge in a mild hotbed with a gentle 

 top heat, not exceeding 60°, and shift as required. The soil 

 should be porous fibr}^ peat and loam, with plenty of sand. 

 The best results, however, are obtained by planting healthy 

 vigorous plants into the border of a conservatory. L. gratis- 

 sinia, flowers pink. L. Pinciana, flowers blush.

LUPINUS. Ll'pine. [Leguminosae, § Papilionacese.] 

 An extensive genus, comprising annuals, perennial herbs, and 

 some few sub-shrubby species, nearly all hardy, easily culti- 

 vated, and possessing considerable general resemblance, so 

 that in a limited garden but a few of the kinds are required. 

 The perennials, L. x>olyphyllus and h. gnmdifolius, throw up 

 long pyramidal closely -set spikes of flowers, from two to four 

 feet in height, according to the strength of the plant. The 

 Lupines will all grow freely in good garden soil, which they 

 very much impoverish. The annuals should be sown in 

 IMarch and April where they are to flower. The perennials 

 are increased by parting the roots, but much more freely by 

 seeds, which ripen abundantly, and may be sown in June, in 

 which case the strongest of the plants will blossom the follow- 

 ing year. The half-hardy sub-shrubby species are also best 

 raised from seeds, and require to be wintered in a dry pro- 

 tected frame, and planted out about May. L. mutaUlis and its 

 variety Cruiksliankil form beautiful objects if raised in 

 August, wintered singly in small pots in a day frame or airy 

 greenhouse shelf, shifted about March, and kept in a cold 

 frame till the end of May, and then planted out in good soil in 

 the flower garden. All the biennials may be treated as annuals. 



LYCHNIS. [Caryophyllacese.] Hardy herbaceous peren- 

 nials, some of which are very ornamental. This may be said 

 of L. Chalcedonica, commonly called Scarlet Lychnis, of 

 which both double and single have been known in gardens 

 for many years, and are as common as the Stock or the Suu-
