This section is from the book "Handbook Of Hardy Trees, Shrubs, And Herbaceous Plants", by W. Botting Hemsley. Also available from Amazon: Handbook of hardy trees, shrubs, and herbaceous plants.
A small selection of hardy perennials, limited to those of good constitution, and little exacting as to the quality of the soil, may be useful. It includes a few for each season, with general indications as to colour.
Crocus vernus and C. versicolor, white,blue and yellow, and striped varieties; Tulipa, Narcissus, and Hyacinthus in variety; Scilla verna, blue; Muscari racemosum and M. botryoides, blue or white; Saxifraga crassi-folia, etc., purple; Arabis albida, pure white; Alyssum saxatile, yellow; Anemone Hepatica, blue, pink, and white varieties; Orobus vernus, lilac and blue; Polyanthus and Double Primroses, various; Viola odorata, varieties; Adonis vernalis, yellow; Cheiranthus Cheirii (Wallflower), in variety; Dielytra spectabilis, rosy-pink; Paeonia officinalis and albiflora, crimson, rose, or white, double or single-flowered varieties; Aubrietia deltoidea, varieties, shades of blue and purple; Phlox subulata, purple, pink, or white; Anemone Coronaria, etc., varieties of many colours; Convallaria majalis (Lily of the Valley); Iberis sempervirens, white; Vinca major and minor, blue and white, and varieties with variegated foliage, etc.
The number of species in cultivation which produce their flowers in summer is, of course, much larger than that of all the other three seasons put together; hence the following selection is relatively more limited than the foregoing: - Campanula persicifolia, C. latifolia, C. rotundifolia, and other species, blue, white, and pink; Centran-thus ruber, crimson, red, and white varieties; Geranium sangui-neum, deep red; G. pratense, etc., blue; Gladiolus communis, violet-purple, red, or white; Gladiolus Gandavensis, etc., numerous brilliantly-coloured varieties; Phlox paniculata and maculata in variety; Althaoa rosea1 (Hollyhock),great variety; Lamium maculatum, variegated foliage; Lilium candidum, white; L. Chalcedonicum, L. Martagon, L. tigrinum, etc., orange, white, etc., spotted with purple brown; Lychnis Chall Usually treated as a biennial. Cedonica, bright scarlet; Antirrhinum, various colours; Pent-stemon, various colours; Papaver orientale, scarlet or orange-scarlet; Lupinus polyphyllus, blue and white; Delphinum formosum, etc. (Larkspur), blue and white; Aconitum Napellus (Monkshood), blue and white; Polemonium caeruleum, blue or white; Ranunculus aconitifolius (Fair Maids of France), double white-flowered variety; R. acris (Yellow Bachelor's Buttons), double yellow-flowered variety; Veronica spicata, blue and white varieties; V. gentianoides, pale blue; Spiraea Filipendula, double white variety; Achillea Ptarmica, double white variety; Aquilegia vulgaris, etc., numerous brilliantly-coloured varieties; Eryngium alpinum, blue stems and inflorescence; Epilobium angustifolium, rosy-purple and white varieties; Iris Germanica, Susiana, etc., various colours; Myosotis sylvatica, blue; Heme-rocallis flava and H. fulva, yellow and tawny; Potentilla atrosanguinea and P. Nepalensis, varieties, yellow to dark crimson; Greum Chiloense, scarlet and crimson varieties; Soli-dago Virgaurea (Golden Rod), yellow; Aster, various species, blue, purple, or white; Anemone Japonica, rosy-purple and other varieties; Tradescantia Virginica, blue, white, and reddish-purple varieties, etc.
The number of species peculiarly autumnal in their flowering is very small; but in favourable seasons a great many of the late summer plants continue to bloom till the end of autumn, or even until Christmas. Chrysanthemum Sinense, various species of Aster, Stern-bergia lutea, and some rare species of Crocus may be mentioned.
To make this series of lists complete, we include a selection of some of the hardiest and most desirable annuals, or plants commonly treated as such. Those species preceded by an asterisk are tender, and must be raised in a frame or greenhouse to get them early in flower : - Amaranthus caudatus (Love-lies-bleeding), crimson; A. hypochondriacus (Prince's Feather), crimson; Centaurea moschata (Purple Sweet Sultan); Calendula officinalis (Common Marigold), orange-yellow double-flowered variety; *Callistephus hortensis, great variety of colours; Centaurea Cyanus, blue, white, and pink varieties; Clarkia elegans and pulchella, pink, lilac, purple, and white varieties; Collinsia bicolor, lilac, and white; Delphinium Ajacis and Consolida (Rocket and Branching Larkspurs), various colours; Dianthus 1 barbatus (Sweet William), various; Esch-scboltzia Californica, orange and other varieties; *Helichry-sum bracteatum (Everlasting Flowers), white, yellow, pink, red, and other varieties; Iberis umbellata (Candytuft), white, lilac, and crimson varieties; Lavatera trimestris, rosy-pink or white; Leptosiphon Androsaceus, etc., various colours; Linum grandi-florum rubrum, deep carmine; Lupinus luteus, albus, etc., various colours; Malcolmia maritima (Virginian Stock), lilac-purple and white varieties; Nemophila insignis, etc., varieties; Papaver Rhoeas (Poppy), Ranunculus-flowered varieties of many colours; *Phlox Drummondii, various; Reseda odorata (Mignonette), Saponaria Calabrica, rose and white varieties; Scabiosal atropurpurea (Sweet Scabious), various colours; Schizanthus pinnatus, several varieties; Silene pendula, rosy-purple and white varieties; Tagetes erecta (African Marigold), orange and sulphur-yellow varieties; Tagetes patula (French Marigold), many varieties; Tagetes signata pumila, yellow and purple-brown; Whitlavia grandiflora, violet-blue and white varieties; *Zinnia elegans, various colours, etc.
We conclude this subject with a short list of Ferns, all of which are indigenous and easily grown : - Lomaria spicant, Asplenium Filix-fcemina, Nephrodium Filix-mas and spinulo-sum, and Aspidium aculeatum in variety, will flourish in almost any ordinary garden soil in half-shaded places. Asple-nium Trichomanes, A. Adiantum-nigrum, Scolopendrium vul-gare, and Polypodium vulgare, require attention in drainage. And finally, Osmunda regalis delights in marshy ground.
