Larch Poles [410 ] Larkspur much good may be done by spraying with a paraffin emulsion. This wash should be applied with force in order to penetrate the wool and so reach the insect. LARCH POLES. The tall, straight trunks of the common larch tree are largely used in garden work as supports for climbing plants. The wood being very durable, these trees are admirably suited One of the most beautiful trees in spring is the Larch, with its pale green foliage and tiny red stars. A useful tree for shelter belts on sandy soils. to such a purpose. The poles are lopped of all side branches unless a few at the top Are retained to form a thicker screen. The bark is then stripped from them (as it harbours insect pests) and the wood is treated with a preservative such as creo- sote. Every description of rustic fencing and screening can be made from larch wood. * LARDIZABALA (lar-diz-a-ba-la. Ber- beridese). The only species, L. btiemata, is an almost hardy climbing shrub with dark purple flowers in October. Propagate by cuttings of half-ripe shoots Insetted in sand under a bell-glass. Plant in equal parts of peat and loam. LARIX (lar-ix. Conifers). Larch. Deciduous trees of distinct and ornamental appearance, and producing timber of verv high quality. The larches are exceedingly attractive in spring with the young shoots of a soft, pale green, and the fascinating red-coloured flowers which develop into attractive glaucous red-coloured cones in early summer. The larches like a well- drained good loamy Soil, and plenty of moisture. They are best increased from seeds, sown out of doors. The rare and choice kinds are grafted in spring on seed- lings of the common larch. SPECIES. L. euToptza (decidua). The "Common" or "European Larch," up to 140ft, Native .of South and Central Europe. 4 tree of very great economic importance, owing to its very valuable timber. Few, if any, trees excel the Common Larch in its quiet beauty and soft tenderness of young green foliage in the spring. The exquisite flowers are worthy of close study. L. Kcempferi. See PSEUDOLABIX. L. leptolepis (Kampferi}. The "Jap- anese Larch," 80-100 ft. Very distinct and useful as an isolated specimen in the garden or park. Immune to *'LarcB canker," and exceptionally valuable on that account. The timber is of a coarser grain than that of the European Larch. LARKSPUR. The annual Delphiniums are usually known as Larkspurs in trade lists. D. ajacis, blue hardy annual, 2£ft., is the common Larkspur, a native of Britain, and has given rise to many of the modern cultivated forms with single 01 double flowers in a variety of shades of blue and rose, and dwarf or "nannm" types of similar colours, 1J ft. JD. consolida. or tall-branching Larfe- spurs, 2-2J ft., are particularly good gar- den plants, being very free flowering and easy to grow. There are some beautiful shades of rosy-scarlet, salmon-pink, rose and pink now obtainable as "named" kinds, such as coccineum, Exquisite Eose, Exquisite Pink, La France, etc., all of which are well worth growing. This section'makes fine pot plants from seeds sown in autumn, and the plants wintered in cold frames. D. grandiflorum, l|-2 ft. Native tf Siberia. WHte, pale blue and dark btoe,
