Deschiption, &c. — The white Petunia is so general a favourite, and so common everywhere, that it seems 
difficult to believe that thirty years ago its very existence was unknown among us. It is a native of South 
America, near the mouth of the Eio de la Plata, where it was discovered, and seeds of it were sent to Europe in 
1823. It was first treated as a greenhouse plant ; but as it was found to ripen abundance of seeds, and to 
propagate readily from cuttings, it was tried in the open air, and found to grow freely as a border flower. The 
seeds are sometimes raised on a hotbed ; but this is unnecessary in the climate of London. They require a light 
peaty soil, or where this cannot be procured, a sandy loam ; and their roots should never be sufiered to become 
quite dry, as they are easily withered by exposure to heat. Too much wet is, however, very injurious, and when 
the Petunias are grown in pots, they should be frequently watered (say twice a day in hot dry weather), but they 
should never be sufiered to stand in saucers. Petunia is from Petun, the name of Tobacco in Brazil.
