Helonias bullata (N. America). 
A plant which requires a rather shady place on 
the side of a bog or on the damp part of rockwork in 
any ordinary peaty loam. In autumn care must be 
taken to clear away the old leaves and to place a 
little dry peat around the crowns of the plant; this 
will prevent its damping off in case of a very wet 
winter. The peat need not be removed in spring, 
as the crown will soon push through, and the 
peat makes a nice dry bed for the new leaves to 
rest upon. 
Hesperochiron pumilus (Idaho to Oregon). 
This plant requires a sheltered position in partial 
shade from ten to twelve o'clock, on the flat, facing 
south-west, in equal parts of leaf-mould and loam 
together with a little fine peat and sand. In spring, 
and again in autumn, top-dress well among the shoots 
with the original compost. 
Houstonia cxrulea and c. alba (Virginia). 
These two plants look well together and should 
be grown on every rockery. They require similar 
treatment to Myosotis rupicola. Plant in a mixture 
of leaf-mould, sand, and good loam in equal parts. 
The plants must not be disturbed or watered after 
the month of September, when a stone should be 
placed so that it may overhang them and thus afford 
protection from the rains of winter, which are very 
liable to cause the loss of the plants unless they are 
carefully guarded in this way. In spring a little top- 
dressing is required, with similar compost to that used 
in planting.
