104 JOTTINGS OF A GENTLEMAN GARDENER 



March, and arranged so that they grow over the stones. 

 Some people think they are not hardy, which is quite 

 a mistake. But a damp sunless site will soon kill 

 them. 



Good Varieties. 



These are extremely numerous, but the reader should 

 try some of the following : 

 Phlox 



amcena (rose-pink), April- June . . . . 6 ins. 



divaricata (blue), May . . . . . . 12 ins. 



ovata (rose-red), May- July . . . . 4 ins. 



reptans (red), April- July . . . . 4 ins. 



subulata (pink), May-Aug. . . . . 6 ins. 



Many beautiful varieties of the last are described in trade 

 lists. 



Polemonium reptans : A fine creeping rock-plant 

 carrying blue flowers, well worth a place in any garden of 

 fair size. There is little difficulty in its culture, except that 

 grubs are rather fond of it. The flowers are given in the 

 spring (March-May). Height about 9 ins. 



Polygonum : There are many finer things for the rock- 

 garden than Polygonums, but they are easy to grow and 

 fairly pretty. Good sorts to try are P. alpinum (12 ins., 

 white, May- June), and P. vaccinifolium (6 ins., rose, July- 

 Sept.). Rich ordinary soil and a sunny position suit them. 

 Plant November or March. 



Primula : The varieties of Primula suitable for the rock- 

 garden are very numerous, but I have had very little 

 experience of them. For my own part, I think there are many 

 more suitable things for the amateur's rock-garden than 

 Primulas, which are not easy to grow in town gardens. 

 Many of my friends have them and they seem to do fairly 

 well in sunny or half-shady positions in good soil. But 

 I understand that it sometimes takes a long while to induce 

 them to bloom. 



Ramondia : This is a pretty plant with leaves clustered 

 in the form of rosettes, worthy of a place in rock-gardens 

 of fair size. A compost of sandy loam, peat, and leaf
