Mrs. Catleugh's Nukseky, Hans Place, Chelsea. — This is one of those places in which 

 certain kinds of plants are grown hy the thousand for Covent Garden market. It is, there- 

 fore, not uncommon to see here a Large houseful of Pelargoniums all in full flower at one 

 time, another of Heliotropes, and frames some hundreds of yards long stocked with Mig- 

 nonette. Potfuls of the latter sown in September last, and wintered in low, cold frames, 

 will soon be in blossom. Mignonette, we need scarcely state, is sometimes sown in small 

 pots, with the view of economizing room ; but, where space is no object^ it gives less trouble, 

 and succeeds equally well sown at once in the pots in which it is to flower. It may be 

 wintered in a shallow frame, as has been done here, from wliich the lights should be re- 

 moved entirely in fine weather, so as to give as much light and air as possible. Many com- 

 plain that they lose their Mignonette in winter ; but this is, for the most part, owing to their 

 keeping it too damp. It should have little or no water for about three months during the 

 dull season, and care should be taken to keep it free from drip, which is sure to kill what- 

 ever plants it happens to fall on. When small pots are employed, particular care need not 

 be taken to have the soil very rich, provided it is light ; but, when sown at once in the 

 flowering pots, richer material should be used, draining well, and placing on the top of the 

 crocks flaky pieces of decayed manure, for the double purpose of afi'ording nourishment to 

 the plants when they are coming into bloom, and for keeping the soil from choking up the 

 drainage. Autumn sown plants, which were shifted into larger pots about Christmas, will 

 blossom from the present time till about May, and another sowing now will succeed them, 

 after which it may be had plentifully in the open ground. Even the worst potfuls should 

 not, however, be thrown away, for, if toj^ped back about this time, they come in nicely for 

 window-boxes in May, which may be managed in the following manner : Having some Tom 

 Tliumb Geraniums (any other drawf, showy plants, as Intermediate Stocks, would do), three 

 of these are placed in a box, one near each end, and one in the middle, and between them 

 are introduced carefully, so as not to break the balls, i)ots of Mignonette, filling the boxes up 

 with rich, light soil, and finishing with a good watering to settle the earth round the roots. 

 The after-treatment consists in keeping the boxes watered always when they require it, and, 

 be it remembered, that if Mignonette is ever allowed to flag, it seldom succeeds so well 

 afterwards. Boxes thus arranged are greatly admired during the summer months, the 

 Geraniums giving brilliancy of color, while the Mignonette furnishes all that is wanted in 

 the way of scent. In addition to the above, all kinds of spring bulbs are grown extensively 

 here, and are at present very gay. Hyacinths potted, and wintered out of doors under ashes, 

 are now moved into heat in succession as they are wanted, and soon burst into bloom. 

 Azaleas and other shrubs are also forced into flower for bouquets, for which, at this season, 

 there is always a good demand. Below the stages of different houses in which no more 

 fire-heat is used than just what will keep out frost, are large beds of most excellent Rhubarb, 

 from which the market supply for weeks has been derived. Tliis has been obtained from 

 roots which were moved under glass soon after Christmas, placed closely together, and 

 covered with soil. The sort is the Victoria, which, although, perhaps, not so red as Salt's 

 Perfection, and some other kinds, is a vigorous grower, and deservedly a general favorite.
