OF ORNAMENTAL ANNUALS. 15| 
extraordinary size. It was discovered in 1831, by Mr. Samuel Richardson fan ofiBcer of the Anglo-Mexican 
Mining Association), and seeds of it were sent by him to J. D. Powles, Esq. of Stamford Hill, which were 
liberally distributed by that gentleman. It was first called Ipomoea ruhro-cyanea, but in 1834, it was figured in 
the Bot. Mag., and its present name given to it by Sir W. J. Hooker. It is remarkable for the abundance of its 
flowers, and the great length of time during which it continues to produce them. Many persons are deterred from 
cultivating this beautiful plant from the idea that it. requires a stove to bring its flowers to perfection. This, 
however, is not the case, as it requires no more care in its cultivation than any other tender annual. In the 
spring of 1835, Mr. Ranch, one of Mr. Loudon's assistants, had some seeds of this plant given to him. They 
were raised in a hot-bed in February ; but only one plant came up, and this was brought into the open air in 
May. In July it began to flower, and it continued producing a succession of large and magnificent blossoms of 
the most brilliant ultra-marine blue till October. The flowers opened every morning three or four at a time, 
and shrivelled up before night into what had the appearance of buds edged with deep rose colour, and which had 
quite withered before the following morning. This plant produced several pods of ripe seeds. We have since 
heard of several plants succeeding under similar treatment. It must be observed, however, that the soil should 
be good and light, and the situation warm and sheltered, and yet open to the sun. Seeds may be had from 
Mr. Kernan, Great Russell Street, Co vent Garden, and other seedsmen. 
OTHER SPECIES OF IPOMOEA. 
Nearly all the following species are marked as stove annuals ; but as they are all very beautiful, and seeds of 
many of them are to be obtained, we gire some particulars of each, that those who like to try them in the 
open air, may be able to choose which they would prefer. There are, indeed, very few stove annuals that will 
not succeed in the open air, if raised in a hot-bed, and not planted out till the latter end of May or beginning of 
June. The situation should be a warm border open to the south, and backed by a wall, and the plants may be 
sheltered occasionally when thought necessary, by a hand-glass or flower-pot turned over them till their roots 
have taken possession of the soil. All tender annuals raised in a hot-bed or stove, should also be gradually 
exposed to a cooler temperature before planting out, and they may even be set in the open air for a day or two in 
the flower-pots they were raised in, before turning them into the ground.
