Mock Orange

Mock Orange (Philadelphus Coronarius) - This kind, with its twiggy growth and heavy perfume, is well known, but less planted now than formerly, or banished to distant parts of the garden, where, under good conditions, it will reach a height of 10 feet, flowering early in May. Some of its garden varieties are distinct and useful: foliis aureis is the Golden Philadelphus; nanus is a dwarf plant, but too shy in flower to be of value; Satsumi is a graceful Asiatic form; while there are varieties with variegated foliage, and others known as flore-pleno, primulaeflorus, and dianthiflorus, with double or semi-double flowers.

Philadelphus Avalanche - Flowers large with a pleasing odour, and so numerous that the branches are weighed down with them.

Philadelphus Boule DArgent - A dwarf spreading plant with double flowers and very fragrant.

Philadelphus Bouquet Blanc - Pure white double flowers borne in profusion.

Philadelphus Candelabre - A dwarf-growing form, with flowers larger than those of P. Lemoinei, and with undulated petals. Very pretty in the rock garden.

Philadelphus Conquete - A free-flowering form, whose branches arch over with the weight of blossoms. These, which are large and double, have almost a Tulip shape, and are fragrant.

Philadelphus Coulteri - A nearly evergreen kind from N. Mexico, of fine habit, and distinct in its waxy flowers with a rosy-purple flush at the base of each petal, forming an inner zone of color. It is somewhat tender, and does not flower freely, but by crossing it has given the new hybrid P. purpureo-maculatus, a hardy and free-flowering kind, differing from anything hitherto seen in this family.

Philadelphus Falconeri - A graceful plant, 16 feet high, of uncertain origin, but probably from Japan. Its pure white fragrant flowers, of waxen texture, and with sharply-pointed petals, are borne freely in June upon wand-like arching stems that droop gracefully under the heavy clusters.

Philadelphus Fantaisie - From the seed-bearing parent this inherited a slight pink tinge towards the centre of the flower, and for hybridising it has proved to be valuable.

Philadelphus Gerbe De Neige - Pure white single flowers nearly a couple of inches in diameter and prettily cup-shaped.

Philadelphus Gordonianus - From N. America, where it is common near the Columbia River. It grows 10 to 15 feet, is of graceful habit, with a profusion of large faintly-scented flowers in July. This kind will do well with a little shade, and its great value is its late blooming.

Philadelphus Grandiflorus - The best large-flowering kind, and one of the finest of hardy shrubs, reaching a height of 15 to 20 feet. Its numerous flowers measure 2 inches or more across, of a good white, and either scentless or faintly fragrant. There are many forms and slight variations of this plant, differing little in general character, and running one into the other. The forms known as floribundus, latifolius, and Zeyheri are all good, and especially laxus, a loosely spreading plant of graceful outline, and not very tall-growing. These forms flower in June.

Philadelphus Hirsutus - Less showy than most kinds, the flowers being small and mostly solitary, but they are scattered so freely that a well-flowered plant of 4 to 5 feet is pretty, and its effect distinct from the other kinds.

Philadelphus Inodorus - Much like P. laxus, but more erect and vigorous, with large scentless flowers, useful for cutting where the odour of other kinds is an objection. It is a plant that forces well, but coming from the southern States, it is a little tender in cold districts.

Philadelphus Lemoinei - A hybrid from microphyllus crossed with coronarius—a beautiful shrub, flowering in the latter half of June, its abundant pure white flowers about 1 1/2 inches across, and with a pleasant fruity fragrance. Of neatly compact habit, it reaches a considerable size at maturity. Its form erectus differs only in its more rigidly erect habit. From this first cross has sprung a race of shrubs of fine habit, refined fragrance, and much freedom of flower, the value of which is as yet hardly shown in our gardens. One of the newest and best is P. purpureo-maculatus—quite a distinct break in color.

Philadelphus Lewisii - From the Pacific coast of N. America, and nearest hirsutus in its hair-fringed leaves. The flowers are a little smaller, scentless, opening at the end of June and early in July. P. californicus is a pretty but rather tender form of this plant.

Philadelphus Manteau DHermine - A general favourite which forms a compact specimen thickly clothed, when at its best, with double creamy-white blossoms.

Philadelphus Mexicanus - A beautiful plant and nearly evergreen, but tender save in the warmest parts of the south-west of England and Ireland, where it occasionally covers warm walls near the sea to a height of 15 feet. The flowers are large and deeply cupped, of waxy texture, and either creamy-white or faintly flushed with rose. Their strong spicy perfume is agreeable, and unlike that of any other kind.

Philadelphus Microphyllus - From Colorado, California, and N. Mexico; hardy with us and richly beautiful in warm soil and a place where its wood is well ripened. The flowers are small and solitary, but freely produced towards the end of June, milk-white, and with a fruity fragrance. It is the tiniest of the genus, rarely reaching 3 feet in height, with slender stems and small glossy green leaves the size of Box, and greyish, with hair on the underside.

Philadelphus Mont Blanc - This, which reaches a height of 4 to 5 feet, is of rather upright growth, with large, sweet-scented flowers.

Philadelphus Norma - A beautiful garden form of Mock Orange. The flowers, which are borne for some distance along the gracefully arching shoots, are each fully 2 inches in diameter, and single, except in a few cases where there is a tendency to an increased number of petals. They are of the purest white, with bright yellow anthers.

Philadelphus Nuee Blanche - This has large shining green leaves, and regularly shaped round blossoms, deeply cupped.

Philadelphus Perle Blanche - The finest double Philadelphus, with very large flowers of the purest white, and borne in great profusion.

Philadelphus Purpureo-Maculatus - This was given a first-class certificate by the R.H.S., which was well deserved, not only for its merit, but also for the possibilities it opened up of quite a new race of these beautiful shrubs, whose blossoms hitherto have been white, or nearly so, whereas those of the newcomer have on each petal a distinct blotch of purple-rose.

Philadelphus Satsumi - From Japan, with freely-branched slender stems of 4 to 6 feet, long narrow leaves, and rather small pure white flowers, in pairs or loosely clustered.
