C. scopdrius L., and C. fldr/dus L., are natives of the Canaries, where they form trailing shrubs 

 from 1 1\. to 3 ft. in height ; and they might probably be treated as half-hardy.

OF THE HARDY AND HALF-HARDY LIGNEOUS PLANTS BELONGING 



TO THE ORDER .BORAGINA^CEiE. 



n. lAtliosph-mum frutkbsum L. (Garid. Aix., p. 68. t. 15.) is a native of the south of Europe and 

 north of Africa, where it forms a shrub from 1 ft. to 3 ft. high, producing its blue flowers in May 

 and June. It was introduced in 1683, but is not common in collections. 



a. h. fruticr.sum majiis Lehm. ; L. josmarinifblium Tcnore, Bot. Reg., 1. 1736. ; and ourfg. 1101. 

 is a native of Naples, and on the mountains of the Grecian Archipelago. 



. Srr L. prostrdtum Lois. Fl. Gall., 1. p. 



105. t. 4., is a prostrate suffruticose plant, 

 a native of France. Introduced in 1825. 

 The corolla is of a bluish purple; and 

 the whole plant is pilose and cancscent. 

 It is, in all probability, only a variety of 

 L. fruticusum. 



K'chium L. There are some species of 

 this genus natives of Teneriflie, the Ca- 

 nary Islands, and Madeira, on rocks. 

 They have mostly splendid blue or white 

 flowers, and some of them, such as E. gi- 

 gantfeum, grow as high as 10 ft. On dry 

 rockwork, in a warm sheltered situation, 

 we have no doubt they would all prove 

 half-hardy. E. candicans L., Bot. Reg., 

 and t. 44.,our^^. 1102., is one of the most 

 common species in British green-houses. 

 It is a native of Madeira, on high rocks ; 

 was introduced in 1777 ; grows to the 

 height of from 2tt. to 4 ft. ; and produces 

 its blue, campanulate flowers in May and 

 June. 



Helwtrdpium peruvianum L., H. p. 

 h(/bridum Hort. Brit., and H. con/7n. 

 b'usum Ruiz et Fav., Bot. Mag, t, 1609., 

 are Peruvian under-shrubs, well known 

 for their fragrant flowers, and on that account introduced into every flower-garden. Plants are raised by 

 cuttings early in spring ; and, being turned out into a bed of rich light soil, they flower freely all the 

 summer, till' they are destroyed by frost. Two or three stock plants should be kept through the 

 winter, in the green-house or pit, to be ready to be placed in a hot-bed or stove, in order to furnish 

 abundance of cuttings in spring. (See the mode of treating Rbsa fndica by Mr. Elles, noticed p. 801.)

CHAP. LXXXIII. 



OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER CORDIACE^. 



Ehre/ia. serrata Roxb. Cor., 1. 1. 55., and ourfig. 1103., is a 

 low tree, a native of the East Indies and China. Introduced 

 in 1795, and generally kept in stoves; but a plant has stood, 

 since 1830, against a wall in the Horticultural Society's Oar. 

 den ; where it grows rapidly, flowers freely, and appears 

 quite hardy. A plant, as a standard, in the open garden, at 

 Messrs. Loddiges's, has the shoots killed down every year to 

 within 1 ft. of the ground ; but the stool sends out fresh 

 shoots every spring, which generally attain the height of 3 ft. 

 or 4 ft. in the course of the summer, and make a fine appear- 

 ance, from the large size of their leaves. The circumstance 

 of a plant like this, a native of the East Indies, and so long 

 considered as a stove plant in England, having lived in the 

 open garden for several years; and, against a wall, having not 

 only lived, but flowered freely; ought to be a great encourage- < 

 ment to cultivators to try almost every kind of plant, what- 

 ever be its native country, in the open air, when they have 

 an opportunity. We do not recommend the trial of scarce 

 and valuable stove plants ; and from the palms, Orchid^ces, 

 and other endogenous orders or tribes, perhaps little is to 

 be hoped for in the way of acclimatisation : but all her- 

 baceous plants that die down annually to the ground, and 

 all exogenous ligneous plants, deserve a trial, when a plant 

 can be spared without injuring the collection to which it 

 belongs. If, after a thousand trials, one species only should 

 have proved sufliciently hardy to endure the open air in our 

 climate, the recompense to the cultivator will be ample. 

 Let him not forget, in making experiments of this kind, that 

 Aucuba jap6nica was originally treated as a stove plant, and 

 Kixtia japonica as an inhabitant of the green- house.
