Plants with Yellow Flowers
Heleniums.—Few plants are better adapted for giving quantities of cut bloom. Either H. autumnale or the improved variety superbum, which is a noble flower, should be grown. August to October.
Helianthus.—A beautiful race of showy flowers. The rigidus variety Miss Mellish, and Soleil d’Or in the decapetalus section, are both worthy of a place; also giganteus with flowers of a paler colour.
Bocconia Cordata.—Plume Poppy. A good foliage plant.
Rudbeckia.—Coneflower. Late summer and autumn flowering plants. R. laciniata, Golden Glow is one of the best, the flowers being produced on slender stalks in great profusion.
Verbascum.—Mullein. Stately plants, attaining, when well grown, a height of 10 ft. V. Chaixi, syn. V. vernale, is a true perennial, which is not the case with several members of the same family.
All attain a height of 6 feet or over.
Oenothera.—Evening Primrose. Several varieties, in spite of their name, bloom during the day. The Sundrops (Oe. fruticosa) with richly coloured flowers, and strong, shrubby habit look charming in the mixed border.
Coreopsis Grandiflora.—The finest of all the Tickseeds, with beautiful flowers on long stems. Especially adapted for cutting. This should be grown in every garden.
Doronicum Plantagineum Excelsum.—Leopard’s Bane. During the early spring and summer months, this is one of the gayest plants in the garden. D. Harpur Crewe is the best.
Lilium Testaceum.—Nankeen Lily. This beautiful lily resembles the well-known Madonna in habit, but the delicate apricot blooms, which are fragrant, make it a welcome addition to the section embracing yellow flowers. A good lily for town gardens.
Anthemis Tinctoria.—Camomile. Generally called the Sulphur Marguerite. A dainty flower, unequalled for cutting. On good soil it grows very free and bushy.
Hemerocallis.—Day Lilies. These are delicately scented, and the foliage of a well grown clump affords a welcome break in the border. H. flava is the best known.
Any of the above would be suitable as intermediates between the tall growing plants at the back and the dwarf subjects in front, of which the following are desirable.
Alyssum.—A. saxatile, Gold Dust, as its name suggests, produces myriads of golden blossoms. It flowers in spring and succeeds best in an open, sunny position.
Cheiranthus Alpinus.—Alpine Wallflower. A dwarf plant, very suitable for edging.
HERBACEOUS GROUPING
Linum Flavum.—Yellow Flax. A hardy little plant with gaily-coloured blossoms.
Œnothera Macrocarpa.—A dwarf evening Primrose with trailing stems on which the large flowers are freely produced. It is perhaps better known as Oe. missouriensis.
The majority of the above flowers are pure yellow in colour. Variety would of course be given by including others varying from deep orange to pale sulphur. An extended list is impossible in the limited space, the object being to suggest a few flowers in the principal colours; however, there will be no difficulty in finding others equally suitable.
