even good sandy loam, with a small admixture of decayed vegetable
matter, suiting them well. Lime in any form must, however, be kept away
both from Azaleas and Rhododendrons. They like a quiet, still place,
where a fair amount of moisture is present in the air and soil.


HARDY HYBRID RHODODENDRONS.

GHENT AZALEAS, as generally known, from having been raised in Belgium,
are a race of hybrids that have been produced by crossing the Asiatic R.
pontica with the various American species noted above, but particularly
R. calendulaceum, R. nudiflorum, and R. viscosum, and these latter with
one another. These have produced hybrids of almost indescribable beauty,
the flowers of which range in colour from crimson and pink, through
orange and yellow, to almost white.

Within the last few years quite an interesting race of Rhododendrons has
been brought out, with double or hose-in-hose flowers, and very
appropriately termed the Narcissiflora group. They include fully a dozen
highly ornamental kinds, with flowers of varying shades of colour.

The following list includes some of the best and most beautiful of these
varieties:--

Alba marginata.
Ardens.
Astreans.
Aurore-de-Royghen.
Baron G. Pyke.
Beauté Celeste.
