several weeks in the early summer is covered with clear bright 

 yellow flowers ; these are produced singly on short stalks, and are 

 much enhanced by the dark, finely-cut foliage. It is an excellent

 in a good sandy loam. It may be increased by seeds or by 

 division.

 known perennials suitable for the rock garden or for spring

 alpine Forget-me-not, is an attractive little plant, growing from 

 2in. to 6in. high, and covered during summer with deep blue 

 flowers having yellow eyes. M. dissitifloi-a is excellent for spring

bearing large yellow

Omphalodes verxa is 

 a spring-flowering plant, 

 somewhat resembling a 

 Forget-me-not : it grows 

 6in. high, and bears 

 loose racemes of small 

 briUiant blue flowers. It 

 is a fine plant for a 

 shaded position in the 

 rockery, and is also suit- 

 able for naturalising in 

 the wild garden ; when 

 once established it soon 

 forms a dense tuft, and 

 increases rapidly by 

 means of runners. A 

 white variety is also in 

 cultivation, which, like 

 the type, flowers from 

 March to June.
