Scrubs for the 
Rockery. 
Shrubs suitable for the embellishment 
of the rock garden do mot, perhaps, take 
such a wide range as one could wish, but 
there is nevertheless a variety of sub¬ 
jects admirably adapted for the purpose. 
One ran with confidence recommend 
Juniperus sabina, popularly known as 
Sr. .1. a beautiful coniferous evergreen 
vrucn hugs the stones and ground in a 
most fascinating way, and is effective all 
the year round. Other forms of the type 
equally suitable are J. s. tamariscifolia 
and J. s. variegata, but the latter should 
not be planted in a too sunny position. 
Euonymous radicans variegata can be 
planted liberally, its delightful silvery 
margined, piak-tirited leaves showing up 
grandly amongst the dwarfer, green- 
foliaged denizens of the rockery. A very 
- c ■ green growing about a foot 
high, a ad having leaves of a shiny green 
on the surface and silvery-white beneath 
covered with bright scarlet berries during 
autumn and winter is Cotoneaster thymi- 
folia. Daphne blagayana, which requires 
a moist shady position, has alternate, 
lance-shaped, evergreen leaves, and pro¬ 
duces fragrant, white, tubular flowers 
freely in dense terminal heads. This 
species is a native of the mountainous 
districts of eastern Europe, and was in¬ 
troduced in 1872. Another suitable 
“ spurge ” with bright pink, sweet-scented 
flowers is D. Cneorum majus, commonly 
known as the Garland Flower. 
A very handsome dwarf evergreen sub¬ 
shrub having trailing proclivities is 
Lithospermum prostratum, "a native of 
south-western Europe. This species pro¬ 
duces bright blue, gentian-like flowers, 
striped with reddish-violet, and is a capi¬ 
tal subject for the rockery if given a shel¬ 
tered, northerly position, and planted in 
well-drained rich loam. 
A collection of rock garden shrubs, 
however small, would be wholly incom¬ 
plete without the inclusion of a few of 
the beautiful hardy Heaths. Of these 
Erica carnea, six inches in height, with 
pale red flowers, and E. c. alba, a white 
form, are very desirable, whilst our own 
native Heaths, E. cinerea and E. vagans, 
are not to be despised. To be successful 
with Heaths it is necessary that the soil 
should have an equal proportion of peat 
or leaf-mould mixed with it, and be free 
from lime. 
Hypericum calycinum makes also a 
splendid shrub for the rockery, its beauti¬ 
ful yellow flowers having a telling effect, 
whilst the evergreen prostrate growths, 
and golden yellow flowers of H. reptans 
leave nothing to be desired. Where the 
expanse of rockwork permits of taller 
and freer-growing subjects than those 
mentioned in the above notes, I should 
recommend Berberis stenophylla fl. pi., 
Cotoneaster microphylla, and a few tufts 
of the white-berried Magellan shrub, Per- 
nettya mucronata.

Maclaren and Sons. 
The Bull Do^ Orchid. 
(Oncidium kramerianum.) 
The accompanying illustration shows 
in Orchid that is at once curious, beauti- 
ul and odd in its particular form. It 
nost nearly resembles the Butterfly 
Drchid (O. Papilio), but it is choicer in 
ts way. It is a native of the Andes of 
Ecuador and New Granada ranging from 
m elevation of 1,000 ft. up to 3,000 ft. 
ft grows upon the trunks of trees fully 
exposed to the sunshine of those latitudes 
md for that reason it requires good ex¬ 
posure in hothouses in order to ripen the 
pseudo-bulbs properly and thereby en¬ 
able it to flower well in the succeeding 
year. 
The upper sepal and the two petals are 
reddish brown, and in no small measure 
resemble the tongue and antennae of a 
butterfly. The lower or lateral sepals 
are much broader and contribute much 
more to the ornamental character of the 
flower. They curve round in such a 
fashion as to appear at a distance to be 
part of the lip, and the contrast in colour 
between these parts is very great, and, 
indeed, serves to guide the insect visitors 
partial to this particular Orchid. These 
lateral sepals are of an orange-red colour 
with golden-yellow streaks passing irregu¬ 
larly across them. The lip is pale yel¬ 
low, bordered with red, thus completing 
a beautiful and peculiarly formed flower. 
The popular name above recorded is 
that by which the plant is known in the 
north of England, and the allusion refers 
to the crest on the lip which has no small 
resemblance to the face of a bull dog or 
some other animal. The botanical name 
kramerianum is derived from Herr Kra¬ 
mer, the gardener under whose care it 
first flowered at Flotbeck Park, near 
Hamburg. 
Rose Frau Lina Strasheim. 
The above is a new variety of Poly- 
antha Rose which was raised by C. P. 
Strasheim last year. A coloured plate 
of it appears in the November number 
of Rosen Zeitung. It was raised as the 
result of crossing R. multiflora with Crim¬ 
son Rambler. The flowers are perfectly 
double, produced in large bunches and 
in the bud state when about to open they 
are wholly of a lake-red colour, gradually 
becoming" entirely rose when opening. 
The flowers are of beautiful form, very 
full and show a' golden-yellow hue. for 
a short time in the centre. It is a sister 
to another variety named Grossherzogin 
Eleanore von Hessen. It may be used 
for a variety of purposes, as it will form 
a high pyramidal bush or may be grown 
on trellis work like other Polyantha 
Roses.
