Lavendula Spica.—The Lavender needs no description.
Leycesteria formosa.—A good plant for a shady place. It grows well under trees, and is very hardy.
Ligustrum ovalifolium (Privet).—The golden form of this is good and bright.
Liriodendron tulipifera.—Grows well here, and is quite hardy, but seldom flowers so far north.
Lonicera periclymenum.—The common native Honeysuckle is an indispensable climber, and will grow almost anywhere; but looks best, perhaps, climbing up trees, or over shrubs or hedges. The variety, serotina, flowers later than the type, and is best known under the name of Late Dutch. L. Sullivantii is a shrubby sort, with not unattractive flowers of a brownish-orange colour.
Magnolia.—The only one I have tried is M. stellata, which has proved quite hardy, and I have no doubt that several others would do quite as well in sheltered places.
Neillia opulifolia (Spiræa opulifolia).—Quite hardy.
Pernettya mucronata.—Does well.
Pieris (Andromeda) floribunda.—Is quite hardy and very beautiful early in the year. Will grow in soils that suit Rhododendrons.
Potentilla fruticosa.—A little summer-flowering shrub, with yellow flowers. It does well on the upper parts of the rock garden, and is quite hardy.
