DEUTZIA.--The old wood should be kept cut out of these, but no shortening of young shoots should be attempted.
ELÆAGNUS.--These require an annual overhauling to keep them in good condition. This should be done in late summer, when the plants should be well thinned out, and all useless growth cut clean away.
ESCALLONIA.--These are usually cut back by frost; but if they escape, _E. rubra_ and _E. punctata_ should have their long growths shortened back in spring, while the other hardy species need not be touched. _E. macrantha_ simply needs thinning. All the smaller growths in the centre should be removed. _E. philippiana_ does not like hard cutting back, but the old stumps must be cut out to make room for flowering wood.

EXOCHORDA.--These usually require no pruning, but if the plants are getting too large or unshapely, they should be cut back immediately after flowering.
FATSIA (_Aralia Sieboldii_).--This is usually cut by frost, but it stands a cutting back in spring, when new growth is soon made which will flower late in the following autumn.
GARRYA ELLIPTICA.--This always flowers on the previous year's wood. Need only be thinned to ripen the new growth.
GENISTA.--_G. tinctoria_ flowers on the young wood, and should be cut back every spring. The other species of Genista should not be pruned, except to keep them in shape.
HALESIA.--These are small trees or large shrubs, and should not be shortened back, but are improved if the growths are kept thinned out, which should be done after the flowers are past.
HAMAMELIS.--Thin out regularly, as they are very apt to get thick and make weakly growths.
HEDYSARUM MULTIJUGUM.--This flowers on the young wood, and should be cut back lightly each spring. The growths can also be pegged down to improve the plant, which is apt to get straggling.
HELIANTHEMUM.--Cut away all dead flowers and seed-pods after blooming.
HIBISCUS.--Thin out in winter, but only shorten the longest shoots.

HYDRANGEA.--These flower best on young wood, and should be cut down in winter. _H. paniculata grandiflora_ should _always_ be cut back to within two inches of the old wood.
