it may be grown out of doors in a sheltered, sunny situation. It
grows well in sandy loam and leaf-mould, and requires a good deal
of moisture in the summer months, though from autumn till spring it
should be kept on the dry side. During winter it is safest to afford
it protection. It is generally raised from cuttings late in summer,
which are kept through the winter in small pots in the greenhouse.
Diphylleia Cymosa.--A very pretty bog plant which blooms from June to
August. Plant in rich, light soil, and give plenty of water. It is
propagated by division. Height, 9 in.
Diplacus Glutinosus (Hard-wooded Mimulus).--This elegant greenhouse
shrub is an evergreen which delights in a rich, sandy loam. It flowers
in June, and is increased by cuttings. Height, 3 ft.
Diplopappus.--Dwarf-growing evergreen shrubs of pretty habit. The
golden stems and leaves of D. Chrysophylla render that variety
specially attractive. A sandy loam is most suitable for their growth.
They require the warmest situation the garden affords, and to be
protected during the winter. Cuttings strike readily. They flower in
August. Height, 2 ft.
Disbudding--The object of Disbudding is to prevent the growth of
branches which, from their position, would be useless to the tree, and
would consequently have to be cut away later on. The process is both
simple and expeditious. The trees are gone over once a week during the
spring, and the useless buds are rubbed off with the thumb, taking off
first those which are most unfavourably situated. The work should be
done gradually, so as not to give any check to the tree.
The term is also applied to the pinching out of flower-buds, such as
those of the Chrysanthemum, so as to give more room and strength to
the remaining blooms.
Disemma.--Splendid evergreen climbers, suitable either for the
greenhouse or in a sheltered position out of doors. Plant in rich,
loamy soil mixed with peat, and, if grown in the open, give protection
to the roots during the winter. They flower in July, and may be
increased by cuttings planted in sand under glass. Height, 20 ft. to
30 ft.
Dittany.--See "Cunila."
Docks, to Kill.--Cut the weeds down to the ground, and run a skewer
dipped in vitriol through the roots.
Dodecatheon.--A hardy perennial, which is very ornamental when in
flower. It grows best in a loamy soil, and is easily increased by
dividing the roots. Blooms in May. Height, 1 ft.
Dog's-Tooth Violets.--See "Violets."
Dolichos Lablab.--Half-hardy annuals. The seed should be sown in
