like a rich, light soil, and come into bloom in June and July. Height,
1 ft. to 2 ft.

Dracophyllum.--Greenhouse evergreen shrubs of an ornamental character.
The pots should be filled with an equal mixture of sand and peat. They
are propagated by planting the young shoots in sand, covering them
with a hand-glass, and plunging them in heat. They flower in June.
Height, 2 ft.

Dragon's Head.--_See_ "Dracocephalum."

Dryas Octopetala (_Mountain Avens_).--A prostrate, creeping perennial
which bears white Anemone-like flowers from July to September. It
thrives in peat, and is increased by seeds, cuttings, or division.
Not being quite hardy, protection should be afforded during winter.
Height, 6 in.

Dutchman's Pipe--_See_ "Aristolochia."

Earwigs, to Trap.--An inverted flower-pot, containing a little dry
moss or hay, placed on a stick, forms a good trap for these pests.
They will also congregate in any hollow stems of plants that may be
laid about. They may be destroyed by shaking them into boiling water.

Eccremocarpus (_Calampelis_).--These climbing half-hardy perennials
will grow in any garden soil, a light, loamy one being preferable.
Sow the seed in autumn on a slight hotbed, pot off, and winter in a
greenhouse. The plants will be ready to turn out on a warm south wall
in April or May. Cut them down in the autumn, and cover the roots with
dry leaves: they will shoot up again in the spring. The foliage
is dark and Clematis-like; the flowers are borne in clusters, are
tube-shaped, and bright orange-scarlet in colour. They are increased
by cuttings.

Echeveria.--Choice greenhouse evergreen shrubs. They grow best in a
sandy loam, with a little peat, mixed with pulverised brick rubbish.
Water must be given cautiously. Young plants may be taken off the
parent in October and pressed firmly, but without bruising them, in
light, rich soil. Cuttings should be left for a few days to dry before
planting. They flower in autumn. In winter keep them in a cold frame,
and as dry as possible. Height, 1 ft. to 2 ft.

Echinacea Purpurea (_Purple Cone Flower_).--A stately hardy perennial,
very pretty when in flower, but hardly suitable for cutting purposes.
It likes a rich, light, loam soil and plenty of sunshine. The roots
may be divided in spring, after growth has fairly started. It blooms
during September and October. Height, 2-1/2 ft.

Echinops (_Globe Thistle_).--Coarse perennial plants, of stiff growth.
