LIST OF FLOWERS 



well in a sandy soil in the Alpine Garden, but wUl not bear crowding 

 or overshadowing. 



LEOPARD'S BANE. See Doronicum. 



LEPTOSIPHON. A hardy annual which is well worth cultiva- 

 tion, and of which there are some pretty dwarf varieties suitable for 

 the Rock Garden. Thin sowing in light soil and in the early autumn 

 is advisable for obtaining robust plants of sufficient size to endure 

 the winter; spring sowing is not likely to succeed so well. L. 

 roseus h a charming little plant with dense tufts of rosy-pink flowers, 

 and there are several beautiful hybrids of various shades of colour. 

 The larger kinds, such as L. densiflorus (both blue and white) and 

 L. androsaceus (lilac), are quite attractive. 



LEPTOSYNE. A useful plant for the mixed border and bearing 

 some resemblance to the Coreopsis. L. StiUmanni is a showy 

 example with bright golden-yellow flowers, blooming abundantly. 

 It is classed in some catalogues as a hardy annual, but in common 

 with other varieties of the Leptosyne it is more wisely treated as a 

 half-hardy annual by sowing in heat early in spring and transplanting 

 into the open in May. L. Douglasi is similar to L. StiUmanni, but is 

 a smaller plant (about i foot high) with flowers rather larger, while 

 L. maritima (a perennial, but best treated as a half-hardy annual) 

 is still smaller — about 6 inches^-and also bears bright yellow flowers. 



LEUCOJUM. The most useful variety is L. cestivum, sometimes 

 called Summer Snowflake, a vigorous plant with clusters of white 

 flowers, delicately tipped with green, gracefully hanging on stalks 

 from 12 to i8 inches high. It blooms in early summer or late spring 

 and will thrive in ordinary soil. As its bulbs increase rapidly it is 

 easily propagated by division, but its flowers are certainly most 

 effective when allowed to remain in dense groups. Another variety 

 is L. vernum (Spring Snowflake), of dwarf growth, about 6 inches 

 high, well suited for the Rock Garden and flowering early, but slow in 

 establishing itself, though once it has taken good root it flowers 

 freely. 



LEWISIA. A crevice in the Rock Garden with some gravelly 

 son where its succulent roots can obtain moisture is just the place for 

 L. rediviva, an interesting little plant only an inch or so high with 

 large flowers varying from white to deep rose. Its moisture-retain- 

 ing roots enable it to revive (as its name indicates) when apparently 

 dead, and if, after flowering, it looks like a mere withered mass it
