In the case of the Grey garden the hedge is of Tamarisk (Tamarix gallica), whose feathery grey-green is in delightful harmony with the other foliage greys. It will be seen on the plan that where this joins the Gold garden the hedge is double, for it must be of gold Holly on one side and of Tamarisk on the other. At the entrances and partition where the path passes, the hedge shrubs are allowed to grow higher, and are eventually trained to form arches over the path.
In the Gold and Green gardens, the shrubs, which form the chief part of the planting, are shown as they will be after some years' growth. It is best to have them so from the first. If, in order to fill the space at once, several are planted where one only should eventually stand, the extra ones being removed later, the one left probably does not stand quite right. I strongly counsel the placing of them singly at first, and that until they have grown the space should be filled with temporary plants. Of these, in the Gold garden, the most useful will be Œnothera lamarckiana, Verbascum olympicum, and V. phlomoides, with more Spanish Broom than the plan shows till the gold Hollies are grown; and yellow-flowered annuals, such as the several kinds of Chrysanthemum coronarium, both single and double, and Coreopsis Drummondi; also a larger quantity of African Marigolds, the pale primrose and the lemon-coloured. The fine tall yellow Snapdragons will also be invaluable. Flowers of a deep orange colour, such as the orange African Marigold, so excellent for their own use, are here out of place, only those of pale and middle yellow being suitable.
In such a garden it will be best to have, next the path, either a whole edging of dwarf, gold-variegated Box-bushes about eighteen inches to two feet high, or a mixed planting of these and small bushes of gold-variegated Euonymus clipped down to not much over two feet. The edge next the path would be kept trimmed to a line.
