EXAMPLE FROM THE FORGET-ME-NOT FAMILY. 11 
with it, there is the deep crimson Bohemian Comfrey (8. 
bohemicum), which is sometimes startling from the depth of 
its vivid colouring ; and the white Comfrey (8. orientale), quite 
a vigorous-growing kind, blooming early in April and May, 
with the blue Caucasian C. 
These Comfreys, indeed, are admirable plants for rough 
places—the tall and vigorous ones thriving in a ditch or any 
similar place, and flowering much better and longer than 
they ever did in the garden proper, in prim borders. There 
are about twenty species, mostly from Southern and Central 
Europe, Asia, and Siberia. 
I purposely omit the British Forget-me-nots, wishing yow 
chiefly to show what we may do with exotics quite as hardy 
as our own wildlings; and we have another Forget-me-not, 
not British, which surpasses them all—the early Myosotis 
dissitiflora. This is like a patch of the bluest sky settled 
down among the moist stones of a rockwork or any similar 
spot, before our own Forget-me-not has opened its blue eyes, 
and is admirable for glades or banks in wood or shrubbery, 
especially in moist districts. 
For rocky bare places and sunny sandy banks we have 
the spreading Gromwell (Lithospermum prostratum), which, 
when in flower, looks just as if some exquisite alpine Gentian 
had assumed the form of a low bush, to enable it to hold its 
own among creeping things and stouter herbs than accompany 
it on the Alps. The Gromwells are a large and important 
genus but little known in gardens, some of them, like our 
native kind, being handsome plants. 
Among the fairest plants we have are the Lungworts, 
Pulmonaria, too seldom seen, and partly destroyed through
