Individual specimens should be so placed that room becomes available as they age and increase in size. They can, for example, be given a surround of shrubs which can later be removed. Instead of trying to estimate the dimensions which the trees in the lists which follow will attain, these have been classified as large, medium or small, hence the abbreviations L, M or S after each name. However, to give some indication of the sizes these categories represent, a larger tree would be one which eventually grows to 4oft(i2m) or more in height; a medium-sized one 25 to 4oft(7.5 to 12m) and a small tree one up to 25ft(7.5m) in height. Those falling in the "L" category will also be suitable, of course, for planting in gardens larger than the half-acre limit in mind. Groups of those classified as "M" will not be out of place in larger settings. Under "S" will be found some trees small enough for gardens occupying no more than a few hundreds of square yards. Attention is drawn particularly to those of formal outline, e.g. Prunus 'Amanogawa' which makes a narrow column. RECOMMENDED TREES To make reference easier, the first mention of any genus is denoted by the use of italic capitals. Deciduous Flowering Trees AESCULUS x CARNEA 'BRIOTIF (L). The best form of red horse chestnut. May. A. indica (L). Pinkish flowers in June, early July. 'Sydney Pearce' is a very attractive cultivar. AMELANCH1ER LAMARCKII (S). The tree often cultivated as A. canadensis. Racemes of white flowers in April. Brilliant autumn colour. CAT ALP A BIGNONIOIDES (L). An imposing large-leaved tree with spectacular white flowers with yellow and purple markings in July and August. CERCIS SILIQUASTRUM (M), Judas tree. Rose-purple, pea-shaped flowers in April and May. CORNUS KOUSA (S). White petal-like bracts freely borne in June, followed by strawberry-like fruits and bronzy-crimson autumn colouring. The variety chinensis has rounder "flowers". C. mas (S). Small yellow flowers on the leafless branches in February. Bright red, edible, cherry-like fruits in autumn. C. nuttallii (M). More tree-like than those listed above. Large white bracts in May, sometimes suffused pink. CRATAEGUS MONOGYNA (M), hawthorn. The species planted to form quickthorn hedges. A wonderful spectacle in our countryside as hedgerow trees. For garden purposes the coloured forms of Crataegus oxyacantha are usually planted, such as 'Paul's Scarlet' (double, red), 'Plena' (double, white), 'Punicea' (single, scarlet), 'Rosea' (single, pink), 'Rosea Flore Pleno' (double, pink). DAVID1A 1NVOLUCRATA (L), handkerchief tree. An unusual tree with large white pendulous bracts in May. FRAX1NUS ORNUS (L), Manna ash. Masses of whitish flowers in May. GENISTA AETNENSIS (S). Graceful drooping branches with yellow pea-shaped flowers in July. Usually seen with more than one trunk from ground level. KOELREUTERIA PANICULATA (M). A slow-growing tree with yellow flowers in July and August, followed by bladder-like fruits.
