Forget-me-nots for the Stream-side 
Short-lived perennials, but it is convenient to 
treat them as biennials, sowing in June in the 
open for transplanting, or in early autumn 
where they are to bloom. The finest is M. 
dissitifiora. Of this and hybrids of M. sylvatica 
there are a number of garden kinds variously 
named in different seedsmen’s lists ; but a good 
form of the typical M. dissitifiora can hardly be 
improved upon. M. alpestris is a charming 
small plant for the rock garden. M. palustris, 
one of the loveliest of our native plants, is a 
perennial, easily raised from seed, for the 
stream-side and damp ground. 
Nasturtium. See Trop^eolum. 
Nemesia strumosa; h.h.a. — Showy flowers, 
variously coloured, mostly about a foot high. 
A small-flowered variety named Blue Gem, of 
soft blue and blue-grey colouring, is a smaller 
plant, very bushy and effective in late summer. 
Sow the last week in March, never in a high 
temperature. 
Nemophila insignis; h.a. — One of the 
loveliest hardy annuals, pure blue with white 
centre, of trailing habit. It is much finest 
autumn sown, when a plant will cover a yard of 
space. There is a white and also a purple form, 
and a white spotted with purple. Nemophilas 
enjoy a cool place in slight shade, and are charm- 
ing in the cooler parts of rock work. 
Nicotian a affinis. — A perennial, but most
