varieties also make themselves at home in any fairly 
good soil, and by sowing seeds in early Summer, 
pricking out the seedlings on a cool border where a 
little leaf-mould has been mixed with the top-soil, 
a good stock of plants may be produced for bedding 
out in Autumn. It will be found that a far better 
display of bloom will thus be produced than if 
planting is deferred until Spring. 
Nepeta. — Two totally distinct species of this 
genus demand a brief note, Nepeta Mussini, because 
it is one of the freest and most continuous-blooming 
subjects in the whole range of hardy perennials, 
making shrubby little grey-leaved bushes with spikes 
of soft lavender-blue flowers, and Nepeta glechoma 
variegata, because it is one of the prettiest little 
trailing plants available for shady banks or positions 
where a ground covering is required. Its foliage 
is rounded, with crimped or scalloped edges, and the 
leaves are heavily splashed and margined with white. 
If the trailing stems are pegged at intervals to the 
soil, roots will be emitted and the layers can be 
severed from the patent plant for transplanting. 
N. Mussini will also root if its branches are layered, 
but it may also be propagated from cuttings taken 
with a ' heel ' and inserted in pans or pots of sandy 
compost under a handlight or frame. 
CEnothera. — It may well be questioned whether 
any garden is really well filled if it contains no

and varieties varying widely in stature, habit of
