cultivation. The Aubrietias, or Rock-cresses, are all hardy 
perennials, and may be reproduced either by seeds or 
cuttings. It is not difficult to please them in an ordinary garden where 
there is no wide choice of soils. They will do well in the rock-garden, or 
in a sunny border where the soil is deep and rich. Seeds should be sown 
in April or May in the open air, and the seedlings planted out in the shade. 
The young plants may be transplanted to their permanent quarters in 
autumn, and will flower in the following spring. Cuttings should be taken 
in the spring and struck in gritty loam. The plants from which the cut¬ 
tings are to be taken should first be placed in a frame to induce new growth 
of tender shoots, these being better for the purpose than the harder out¬ 
side growths. They should be kept rather close after insertion, and when 
well-rooted and hardened off, they should be planted in a shady border, 
and in autumn placed finally where they are to bloom. A third method of 
propagation is to layer the stems of older plants after flowering, covering 
them with soil. They freely root, and send up numerous shoots which 
develop into new plants, though at present connected with the old. They 
will produce fine masses of bloom in the spring, after which the new 
plants may be separated by cutting through the layers.
