GENISTA (Ulex) HISPANICA. SPANISH FURZE.

Name.Country or Origin and Natural Order.Colour and Season.General Remarks.
GenistaLeguminosæ......A popular group of shrubs, allied to the Cytisus, and delighting in dry sandy soils. A group of the finer species is very rich in colour when in flower.
*G. æthnensisSlopes of Mount Etna, in SicilyGolden yellow; July and AugustThis Broom is perfectly hardy near London. It is one of the rarest of shrubs in gardens in spite of its beauty, and it flowers in July and August, a season when even inferior flowering shrubs are not plentiful. It has a rather gaunt, yet not inelegant habit, and assumes a somewhat tree-like form when old, being often reduced to a single stem at the base. It carries, however, a wide head of thin cord-like, arching or pendulous branches, with little or no foliage except when the wood is quite young. The flowers are of a rich golden-yellow, and during the series of hot summers we have experienced in recent years have been especially abundant. It would, indeed, be difficult to find a shrub better adapted for hot, light soils than this, a fact that is amply proved by the way it succeeds at Kew. It is a good plant for associating with medium-sized evergreens, which hide its bare stems and render it more effective when in flower. It grows 10 feet to 14 feet high, and is thus one of the tallest—if not the tallest—of the Brooms hardy in Britain. It ripens seed freely, and is best propagated by that means.
G. cinereaSouth-West EuropeYellow; JulyThis is a shrubby plant for the rock-garden in sunny places.
*G. hispanicaSouth-West EuropeYellow; JulyA dwarf and charming shrub, 1 foot to 2 feet high, and when in bloom covered with flowers. One of the best of its race.
G. monospermaSicilyWhiteNot well known but interesting. Sandy soil. Tender.
G. pilosaEurope, EnglandRich Yellow; May and JuneA prostrate plant for the rock garden. Ordinary soil.
*G. radiataCentral and Southern EuropeYellow; SummerVery beautiful when in full flower on the rock garden, and will even succeed in a rough wall.
G. sagittalisEuropeYellow; May and JuneAnother dwarf species for rock garden.
G. tinctoriaBritainYellow; July and SeptemberThe double variety flore-pleno and elatior are finer than the species. Elatior makes quite a bush and is very attractive when in full bloom.
*G. virgataMadeiraYellow; June and JulyThis must attain a certain age and size before it displays its full beauty, small plants flowering sparsely or not at all, while older specimens are a glorious sight during the period of flowering. Thoroughly hardy in at least the southern half of England, self-sown seedlings of it having been known to spring up in considerable numbers under old plants in sheltered positions. In a shrubbery or wood it makes a brilliant blaze of yellow. It succeeds in almost any soil or situation provided it is not too heavy or wet. Under favourable conditions it reaches a height of 16 feet to 20 feet, with rather straggling branches, every little twig of which is covered with flowers in season. The leaves are about half an inch in length, and covered with white, silky hairs on the under side and a few scattered ones on the upper surface. Easily raised from seed. Excellent for barren land.

Gordonia Lasianthus (Loblolly Bay)Virginia to Florida; TernstrœmiaceæWhite; JulyA sub-evergreen shrub 6 to 8 feet high, bearing beautiful white flowers like single Camellias. It needs a sheltered spot and a moist peaty soil.
G. pubescensGeorgia and FloridaWhiteOf rather smaller growth than the preceding, while the leaves are pubescent underneath. The flowers, too, have the tuft of yellow stamens more pronounced than in G. Lasianthus. Both need the same treatment.
Halesias (Silver Bell, or Snowdrop trees)Styraceæ......This is a beautiful family of flowering trees, named after Dr. Stephen Hales. The flowers are like the snowdrop in shape, hence the name, and there are two distinct sections, American and Asiatic. The Halesias like a rich, moist, loamy or peaty soil. Although often trees of considerable size in their native homes, they mostly retain a somewhat shrubby character in this country. All the species, however, except H. parviflora, can, by pruning away the lower branches, be made to form small trees.
Halesia corymbosa (Syn. Pterostyrax corymbosum)Japan, in the province of HigoWhite, tinted with pink or yellow; SpringMr. Bean writes in The Garden, May 19, 1900, p. 361, about this species as follows: "I do not know if there is any authenticated instance of its having flourished in Britain or even in Europe, most plants so called being H. hispida. It was first found on the mountains of the most southern of the main islands of Japan, in the province of Higo, and may possibly not be quite so hardy as H. hispida. Judging by pictures and dried specimens, its racemes, whilst having much the same general character as that species, are shorter, broader, and more branched, and the flowers are not so numerous on the branches of the racemes, and the fruits are more downy than bristly. The flowers have the same one-sided arrangement on the racemes."
H. dipteraSouth-eastern United StatesWhite; late SpringNot a common species, and dwarfer than H. tetraptera. The flowers are white, Snowdrop-like, and are borne on slender pendulous stalks as in H. tetraptera; they differ, however, in having the corolla almost lobed to the base. Very distinctive is the seed-vessel, which has but two prominent wings, the other two being only rudimentary. Whilst not perhaps equal in merit to H. tetraptera this species appears to have been undeservedly neglected. Its dwarf bushy habit will also render it more suitable for some positions; it loves abundant moisture at the root. It blossoms rather later than H. tetraptera.
H. hispidaChina and Japan. Introduced about 1870WhiteThis belongs to the Asiatic group of Halesias, and is very distinct from the American species. It is a vigorous shrub, a small tree with large oblong leaves, and small flowers, which are very numerous on the raceme, which is 4 inches to 8 inches long. One striking peculiarity of the raceme is that the flowers are arranged on the upper side only of its branches (a somewhat similar arrangement is seen in Freesia flowers). The seed-vessels are covered with bristly hairs. Mr. Bean says, "Whilst perfectly hardy at Kew in the open, it blossoms more freely on a wall. The finest specimens I have seen of this Halesia are growing near a carriage-road leading to Mr. Gumbleton's house and garden at Belgrove, Queenstown." It flowers in this country in June.
H. parvifloraSouth-eastern United States. Introduced in 1802White; end of MayThis is invariably a shrub. It is represented in the Kew collection by a large bush, which flowers as a rule with great freedom towards the end of May each year. The arrangement of the flowers is more racemose than fasciculate, and whilst they are very abundant they are not so large as in H. tetraptera or H. diptera. They are white and Snowdrop-like. The seed-vessels are only slightly and unequally winged. On the whole, therefore, the species is easily distinguished from its two fellow American species. The grace and abundance of its bloom make it well worthy of cultivation wherever a variety of hardy shrubs is desired.
*H. tetraptera (Common Snowdrop tree)South United States. Introduced by a London merchant named Ellis in 1756White; MayA beautiful tree. Whilst according to Prof. Sargent it occasionally attains a height of 80 to 90 feet in its native country, it is seldom more than 20 feet high in the British Isles. Its flowers are like pure white Snowdrops, hence the popular name. The seed-vessels are 1½ inches to 2 inches long, and have four prominent wings that transverse them lengthwise.
H. t. MeehaniThis originated as a seedling in Meehan's Nursery, Germanstown, Philadelphia.WhiteA very handsome and distinct variety, with shorter flower-stalks, and thicker and more coarsely wrinkled leaves than the type.
