slight shade. Chips of stone placed on the soil around the plants are useful in keeping the 

 surface roots cool. Geums are of easy culture in well-drained, moderately rich soil. Gypso- 

 phila cerastioides is benefited by an admixture of old lime rubbish with the soil, which should not 

 be heavy and damp. Helianthemums grow well on banks of sandy soil. Hutchinsia alpina 

 grows freely, and quickly spreads into large patches, in porous soil, in a slightly shaded 

 situation. 



The Iberis family will flourish in ordinary garden soil if given a position well exposed to 

 sun and air. 1. gibraltarica, however, must have a very well-drained, light compost if it is to 

 survive the winters. Ionopsidium acaule is an annual that sows itself in light soils. Libertias 

 grow well in sound loam, and Linums are not particular in the matter of soil, though a porous 

 loam is to be preferred for them. Lithospermum prostratum does well in peat and disintegrated 

 granite in a position fully exposed to the sun. Lychnis Lagasca? is at home in sandy loam 

 on a sunny slope. The Malvas will thrive in moderately rich garden soil. Morisia hypogasa 

 succeeds in a deep, gritty soil of peat and loam. Myosotis alpestris should be planted in porous 

 soil that may be kept in a moist condition during the whole of the growing and flowering season, 

 during which time slight shade is also beneficial. Nepeta Mussini will grow in any light sandy 

 soil. Omphalodes verna will succeed in light or heavy soil, in full sunshine or in shade. 

 O. Lucilia? should grow in a mixture of peat and loam with which grit and small broken pieces of 

 stone have been mixed. Onosma tauricum should be planted in a well-drained, sunny portion 

 of the rock garden. The Oxalis thrives in warm and dry situations in sandy soil. Pentstemons 

 flourish in a rich, porous loam. The dwarf, so-called Alpine Phloxes succeed best when given 

 a deep, moist root-run in porous soil between rocks while their foliage is fully exposed 

 to the sun. The dwarf Polygonums will grow in ordinary soil. Ramondia pyrenaica is most 

 satisfactory when planted in fissures on the north side of perpendicular rocks, where it gets no 

 sun, in gritty peat. Saxifrages and Sedums will grow in any open, porous soil on the rockwork,
