102 JOTTINGS OF A GENTLEMAN GARDENER 



valuable for the rock-garden, and should be planted in 

 sandy soil in a sunny position in October or March. They 

 may be propagated by seeds sown in the spring or by 

 cuttings in August. 



Good Varieties. 

 Hypericum 



coris (yellow), June- July . . . . 6 ins. 



olympicum (yellow), June-Aug. . . 12 ins. 



Iberis sempervirens (Candytuft] : This is the perennial 

 Candytuft, a grand plant for drooping over stones in the 

 rock-garden. Ordinary soil will suit it and a sunny position. 

 There are several hybrids which are good. The height of 

 I. sempervirens varies from 4-12 ins. Its white flowers 

 are borne freely every spring. 



Linaria : There are many better things for rock-gardens 

 than Linaria, but as they are quite pretty plants and easy 

 to grow if given ordinary positions, I include them. They 

 spread quickly. 



Good Varieties. 

 Linaria 



alpina rosea (rose-pink), May-Sept. . . 4 ins. 

 pallida (violet), May-Sept. . . 6 ins. 



Lithospermum : An easy quick growing plant for the 

 rock-garden. It often grows too freely and is inclined to 

 cover up other plants, but it can be kept in bounds by 

 cutting back slightly after flowering. It thrives best in a 

 sunny position in a light sandy soil, and can be planted in 

 November or March. Propagated by seeds or cuttings. 



Good Varieties. 

 Lithospermum 



intermedium (blue), June-Aug. ..*y 9 ms - 

 prostratum (blue), April-Aug. ^y 4-6 ins. 



Lychnis : The Lychnis is a very good plant for the 

 beginner's rock-garden, for it is of quite easy cultivation. 

 Good light rich moist loam and a sunny position suit it, 

 and it can be planted in November or March. L. Haageana 

 described in Chapter VII is suitable for the rock-garden.
