We know from experience raised beds may, in some instances, be made very effective and at trifling expense. Take one, two or three - according to size - rough old stumps and place them in the center of the bed, rough side uppermost, and plant climbers and trailers in the bed and allow them to run over the stumps, but do not - as we have often seen attempted - plant in the cavities of the stumps, or failure must result. Some of the newer Clematis make splendid permanent beds in some places, and we doubt not would succeed admirably here. We have seen most excellent effects produced by planting good sized beds with low growing Evergreens, Juni-perus, Retinosporas, Box, etc., interspersing a few good flowering plants for the summer months. Do not plant Rhododendrons singly, nor in dry exposed places - I speak here of summer exposure. On the north side of a hill, in the shade of, but at some distance from trees, if the soil be a nice loam or a peat soil, clumps of Rhododendron, Kalmia, etc., will thrive. Again, why should the hardy Azalea be entirely overlooked? Our native kinds, with some of the more beautiful Ghent varieties interspersed, are charming when in bloom, but of all permanent beds, we have Been nothing to surpass a bed of roses pegged down.
Strong growing, free blooming varieties, suit this latitude, and the beds well made, properly planted, and the growth kept pegged down to the earth, and success is certain. - Am. Farmer.
