THE FLORIST AND POMOLOGIST. 
[ June, 
dwarf, tufted, horizontal, and of a somewhat glaucous green ; Picea Hudsonica , 
also dwarf, tufted, and horizontal, but with dark-green foliage ; the hardy Heaths, 
Daphne Cneorum , &c., are all good dwarf subjects for masses or margins. Young 
plants of Thuja Vervaeneana are remarkably effective for grouping, as they take 
on in winter a yellowish hue, flushed with a warm brown,—a kind of light 
yellowish-bronzy tint, which is very effective. Cryptomeria elegans , a fine bushy 
shrub, with horizontal branches, and Petinospora ericoides , which is dwarf, 
slender, and columnar, assume a purplish tint in winter. All these are thoroughly 
hardy, and not likely to disappoint those who select them, except it be through 
incompatibility of soil, or situation. 
The grand family of Rhododendrons alone would furnish a splendid evergreen 
garden, standards being very effective, and dwarf masses, ultimately growing up 
into ample bushes, being gorgeous in the extreme during the blooming period. 
Rhododendrons for the purpose here indicated should, however, be selected for 
two special qualities—bold, clean, handsome foliage, and hardiness of constitution, 
to enable both leaves and flower-buds to escape injury in severe winters. 
These qualities are only to be found in the sorts bred from R. catawbiense , those 
which contain the blood of the supposed hardy ponticum being liable to have 
their flowers destroyed in the bud. ' 
These are mere indications of the choice materials to be had for planting 
the Evergreen Garden, which may be infinitely varied in arrangement.—T. M. 
IMPATIENS JERDONI2E. 
f ERHAPS there is not a more beautiful member of the numerous family of 
Impatiens than that dedicated to Mrs. Jerdon, except it be the allied 
? scarlet-flowered Impatiens Walkeri. These form a remarkable group in 
which the flowers consist almost wholly of the enlarged spur. I. Jerdonice 
was introduced from the Neilgherries about twenty years ago (1852) ; and like most 
annuals is very “ impatient ” of being kept from one season to another—that is, 
treated as perennials generally are. To do so it must be reduced, by a process of 
careful drying, to a state verging on dormancy, to be again started into life and 
activity at the very nick of time, when to maintain it in an inactive state longer 
would injure it beyond recovery. Though it has always been set down 
on authority as a “ greenhouse ” annual, yet I think few cultivators will be found 
to admit that it is possible to grow and winter, and then to start and grow it again, 
in what is strictly called a greenhouse. It requires a higher mean temperature 
than this, and if not that of a stove proper, at least it must have as much heat 
as is afforded in what is called a cool stove, or by some gardeners an intermediate 
house. Nor can I understand how it has been written down a “ greenhouse ” 
annual, seeing that as a native of the Neilgherry hills it naturally enjoys a tem¬ 
perature of about 80°, besides the softening sea influences from the Malabar coast. 
Expert culturists may indeed maintain a goodly-sized one-year-old plant in toler-
