transplanting is necessary it should be done in 
Spring, not in Autumn, and a situation must be 
chosen where there will be no stagnant moisture 
around the crowns in Winter. In hot countries, 
it is true, Kniphofias grow luxuriantly in boggy 
marshes, but not so in Britain. The best clumps we 
have met have grown either on gravel or chalk, but

We may have tall robust giants like Aloides grandis

keep the crown just high enough to prevent soil 
from smothering it.

and free-flowering Lathyrus latifolius in its rose and

might well pay them more attention. Luteus with 
its yellow flowers, and aureus, rich orange, flower as 
early as April. Pannonicus is a delightful plant
