THE GREATER BOG-PLANTS 187 
have it thriving in the wild-wood garden now, and making 
a mock of brambles and long grasses. As for propagation, 
you have only to cut off a few inches of black tentacle in 
early spring, with a green bulge at the end, and plant it 
firmly in good soil. Soon the lopped member will shoot 
and start creeping. Once started, it will ramp on and on, 
over naked rock or concrete, seeming to need no more 
nourishment than it gets from its original starting-point 
and the moisture all around. 
Who is there that will not grow Cypripedium Reginae ? 
I need say no more. I have already chanted the psalm 
of the Queen-Slipper. Give it light rich peaty loam, 
perfect drainage, much enrichment of old leaf-mould, a 
fair degree of moisture, and the shelter of neighbours. 
Then you will do well and permanently with the Cypri- 
pedium. Especially may one suggest the Osmundas regalis, 
and cinnamomea,—or Struthiopteris,—as companions for 
the Queen-Slipper, which never looks lovelier than when 
peering from amid the rich filminess of ferns. The 
Bamboos might serve, you would think, but not one of 
them may ever be trusted within two hundred yards of so 
choice and forward a spot as you would naturally choose 
for the Cypripedium. Eulalia, again, tall and elegant, 
is only fitted for such high places as you might otherwise 
grace with the Pampas. A specially dainty occupant of 
the large bog is the seldom-seen Poterium canadense. 
Our own Poor Man’s Pepper-box, Poteriwn sanguisorba, 
is too dull in flower, despite its exquisite foliage, to find a 
corner, but canadense, having the same choice design of 
leafage, multiplies the whole scheme by three, and is a 
fairy giant of a plant, sending up in very late summer 
and all through the autumn, six-foot stems, terminated 
by long fluffy spikes of white, similar to the Cimicifugas, 
in a way, but far more attractive. This will grow in any 
rough place, and needs no trouble at all.
