An American florist advertises the following in the London papers. We have heard nothing of them in this country, and should like to know if any of our readers can explain. The description reads like the common Hibiscus Moscheutos of our Jersey swamps:

"These grand hardy Hibiscus, which were produced after years of careful cultivation and hybridization, we now offer for the first time. Though none have previously been sold, they are not altogether unknown, for hundreds have seen and admired them at Floral Park during the past two or three years, and considerable has been said about them through the papers. They are perfectly hardy in any place and each spring send up numerous branches, which, from well established roots, grow 5 to 8 feet high, forming a dense clump, as seen in the cut, which is truly a showy object. The enormous flowers are produced in great profusion from July to September, and are over a foot across, being the shape of large saucers. The colors range from pure white, through all the shades of blush and pink, to deep brilliant rose. Plants from seed bloom the first summer, and increase in size and beauty every year for several years".
