FERNS—Continued 
POLYSTICHUM *mohrioides Lemmonii — A very rare Shield 
B> Fern from cliffs and rocky slopes at high elevations in our 
far western mountains. The plants are densely tufted and 
reach 8 to 10 inches. The evergreen fronds are twice pin- 
nate and the segments overlap, especially near the tip. 
Requires a gritty, leafmold mixture and a north exposure. 
Pots, $1.25 and $1.50. 
*mohrioides scopulinum—Very much like the above but only 
E> 6 to 8 inches tall and the fronds more shiny and less di- 
vided. Requires the same culture, equally rare and attrac- 
tive. Pots, $1.25 and $1.50. 

DRYOPTERIS FRAGRANS 
(See page 39) 
GAULTHERIA—Belongs to the Ericaceae and requires a cool 
root run and acid soil, with shade or light shade and mois- 
ture during the dry season. Plant in peaty, woodsy soil. 
Fine as shrubby groundcoyers under Rhododendrons or 
Azaleas or in the woodland garden. Protect the foliage 
in Winter with a mulch of evergreen boughs in cold climates 
with little snow. 
*humifusa—A very compact evergreen creeper from the high 
Cascades with small, rounded, leathery leaves, white urn- 
shaped flowers in mid-Spring, and scarlet “‘berries’’ later. 
1% in. Hardy but not easy. Pots, $1.00; field, $1.50. 
*nummularifolia—Procumbent evergreen with reddish, hairy 
stems and small, oval leaves, dull green above. Rarely 
flowers but a wide-spreading groundcover for mild cli- 
mates. Rare Himalayan plant. Pots, $1.00; field, $1.50. 
*nummularioides—Very much like the above but more vigor- 
ous and with larger, conspicuously veined leaves. A few 
white, pitcher-shaped flowers from the leaf axils followed 
by bluish-biack fruit. 6 in. Himalayas. Groundcover for 
mild sections. Pots, 75c; field, $1.25. 
*ovatifolia—A slender, much-branched shrub with prostrate 
or spreading branches, 8 to 12 inches long, the young twigs 
reddish-pubescent. White flowers and later, bright scarlet, 
flattened fruits. 5 in. The handsome, evergreen foliage 
makes a fine, hardy cover. A native of our western moun- 
tainss Pots. Gane dap l. 25) 
*tricophyHa—A lustrous creeping species from the Himalayas 
and very rare in cultivation. Thin upright stems to 4 inches 
carrying small oval leaves of rich, glossy green and mar- 
gined by short, stiff, brown hairs. Lovely pink bells with 
“red sepals in late Spring followed by 4arge blue berries. 
To our knowledge not offered before in this country. Pots, 
$1.50 and $2.00. 
GAYLUSSACIA *brachycera—Related to Vacciniums, making 
low, evergreen bushlets with heads of pinkish, pitcher-like 
flowers in late Spring, followed by the blue berries in the 
Summer. Peaty, acid soil in light shade. 12 to 18 in. A 
very refined plant. The tiny, glossy leaves take on brilliant 
scarlet shades in the Autumn. Choice and rare. $1.50. 
GENISTA (Broom)—The remarks about Cytisus apply to Ge- 
nista also. Unique shrubs for sunny, dry locations. 
*horrida—A very rare and choice, spiny shrub. Forms silvery 
balls with yellow flowers during early Summer. Requires a 
very well-drained positon with plenty of grit in the soil and 
full sun. 10 inches or more, in time. Like Erinacea, a 
“hedge-hog’’. Different. Pots, $1.00; field, $1.50. 
**pilosa—One of the most dwarf and compact of all Genistas. 
Creeping, with very small foliage and yellow flowers, from 
late Spring to early Summer. A dainty, slow-growing gem. 
Pots, 75c; field, $1.00. 
GENTIANA—The Gentians furnish the scree and rock gardens 
with some of their most glorious subjects. No color can 
compare with the blue of Gentiana acaulis and its forms. 
While some are rather difficult, there are many which are 
comparatively easy and all will repay any effort made to give 
them conditions to their liking. The alpine species, in gen- 
eral, are singular in requiring an extremely large amount 
of root moisture, combined with good drainage. One diffi- 
cult problem is to keep plants as cool as they are in their 
mountain homes without shading them more than nature 
does. Planting on the north or east side of a well-sub- 
merged rock, so that the roots have the cooling effect 
of it, is one answer. Medium-sized stones can also be placed 
at the bottom of hole in which plant is placed, so that roots 
come in contact with them. Nearly all Gentians enjoy plenty 
of leafmold mixed in the soil. 
*<acaulis excisa X angustifolia—A hybrid with rather long, nar- 
row leaves which are very glossy and dark green. The usual 
huge upturned trumpets of intense blue on short stems. 
Very rare. $2.50. 
**cachemerica—Found in Kashmir at about 12,000 feet eleva- 
tion. Makes tufts of ovate foliage, rather pale green, with 
the sapphire-blue flowers sitting at the top of 3 to 5 inch 
stems, wearing their lobes erect. A very rare species and 
stock limited. $2.00 and $3.00. : 
*yerna—At the very head of the alpine plant aristocracy. The 
B> Spring Gentian is a conspicuous part of the flora of the 
Alps and its beauty is described by Farrer in his most glow- 
ing terms. His description is well worth reading. Briefly, it 
is a tufted or mat-forming Gentian with shiny, dark green 
leaves and flowers of intensely luminous blue on 2 to 3 
inch stems. There is still much controversy about its cul- 
ture but we recommend a cool exposure, preferably north, 
or light, dappled shade and a mixture of leafmold, thor- 
oughly decayed manure, fibrous compost, and stone chips. 
A chip mulch under the crown and around the plants is im- 
portant. Plant in early Spring. Pots, $1.50. 
GYPSOPHILA *aretioides—From the high Alps of Persia, most 
distinctive and a very rare plant. Dogs not resemble any 
other Gypsophila in appearance, because it makes flat, 
hard and dense mats, like a very compact Silene acaulis, 
studded with white, almost stemless, flowers. Must have 
perfect drainage, doing best in scree or crevice. Pots, $1.25 
and $1.75. 
HABERLEA *Ferdinandi-Coburgii—Much like the next but the 
flowers are more blue and leaves less hairy above. Diffi- 
cult unless planted in a north-facing wall where the air is 
humid. Rare. Pots, $1.00 and $1.50. 
*rhodopensis—Similar and closely related to Ramonda and 
requiring a similar treatment in a crevice, facing north, with 
leafmold and loam. Flowers like a small Gloxinia, lilac lav- 
ender speckled with gold. Rare. Pots, $1.00 and $1.50. 
HELICHRYSUM *bellidioides—A sun-loving Everlasting, form- 
ing mats of green leaves, silvery-gray backed, and glisten- 
ing, white, scaly flowers. 5 in. For warm climates and 
particularly open soils with perfect drainage. A rare New 
Zealander. 75c and $1.00. 
*frigidum—A very rare species from Corsica, for the scree. 
Ash-gray tufts and white flowers. Prot-ct from exces- 
sive rain and cold. A fascinating, moss-like rarity. Pots, 
75c and $1.00. 
IBERIS “saxatilis (petraea of gardens) —Dark green, prostrate 
bushlets with rather fleshy twigs and foliage. Heads of 
closely-packed flowers in very early Spring and often again 
in the late Fall. A tiny gem only 2 inches high. Rare and 
unusual. 75c and $1.00.
