236 ROCK GARDENING FOR AMATEURS 



plants for next spring. There is also a charming white- 

 flowered form, as well as one with double flowers. 

 L. grandiflora is a Japanese plant, growing over twelve 

 inches high, with a cluster of flowers on each stem in 

 summer. Each flower is an inch or more across, fringed 

 at the edges, and varies from deep crimson to scarlet, 

 pink, and white. It is best grown in a shady place, 

 planted in moist soil with plenty of decayed leaf-soil. 

 Similar to this is L. fulgens, while the various forms of 

 L. Haageana are the result of a cross between the two 

 species. All are readily raised from seed, or may be 

 increased by division in autumn or spring. L. Lagascae 

 is a pretty dwarf plant from the Pyrenees, with bright 

 rose-coloured flowers in May. It likes a sunny place, and 

 should be planted in fissures or cracks between large 

 stones, and here will produce masses of its lovely blooms. 

 It may also be grown in sandy or stony soil in any exposed 

 position in the rock garden ; it commences to flower 

 early in summer, and continues for a long period. It 

 is readily increased by means of seeds sown in spring. 

 L. Viscaria is one of our native plants ; it has long, grassy 

 leaves, and bears in early summer showy heads of rose- 

 coloured flowers on stems about a foot high. It seeds 

 very freely, and self-sown seedlings come up in quantity 

 in rocky crevices round about old plants. It varies a 

 good deal in colour, one of the most charming being the 

 pure white form, var. alba. There is also a double- 

 flowered form, which, like the other, is easily increased 

 by division.
