PLANTS WORTH GROWING 185 
places a little protection afforded by furze boughs, 
bracken, or similar material may with advantage 
be afforded. The one thing that should be insisted 
upon is that plants purchased should be pot grown. 
The Romneya will not lift and transplant in the way 
of ordinary plants. Propagation is best effected by 
cutting up strong roots with eyes, starting in pans 
of sand on a gentle bottom heat, and potting off 
singly as soon as growth becomes active. Grow 
on into five-inch or six-inch pots, and when well 
rooted transfer in Spring or early Summer to per- 
manent quarters. 
Rudbeckia. — Some of the Rudbeckias are strikingly 
handsome border plants. Some are very useful for 
cutting, but some are coarse in growth, stiff in 
appearance, and not sufficiently showy or effective 
to be really useful except as fill-up subjects for 
rough and unimportant places. 
The best are Califomica, nitida, and speciosa, 
whilst the double form of laciniata is a good plant 
for positions where a tall, strong-growing fill-gap is 
required. The Rudbeckias are hardy, bright yellow 
in colour with conspicuous cone-shaped disks. 
Salvia. — The Sage family includes a few plants of 
considerable decorative value. For the most part 
they are of shrubby or sub-shrubby habit, and their 
peculiarly-shaped hooded flowers are of bright and 
showy colours. Chamsedryoides, blue ; Grahami, 
bright cherry crimson ; grandiflora, blue and white ;
