lasiocarpa, the Rocky Mountains fir, and its variety arizonica. Both will grow slowly to a height of 60 to 7oft(i8 to 21m) but, in spite of their eventual height, they have distinct possibilities for smaller planting areas in view of their extremely slim, pyramidal outline. Again there are, as is inevitable with montane species, several dwarf selections. Golden foliage is scarce among the cultivars of the silver firs. A. nordmanniana 'Golden Spreader' is most attractive and one to be searched for. The habit is low-spreading, and it appears to be completely reliable as a dwarf. CEDRUS (cedar) If we think of cedars we almost certainly picture a great specimen of Cedrus libani, the cedar of Lebanon-growing in parkland or in a similar position-or the slightly smaller, but still substantial, C. atlantica f. glauca, displaying its fine blue foliage to advantage. All too often the last-named is to be found in far too confined conditions. Of the four species of Cedrus, only C. brevifolia is suitable for the half-acre (.205 hectare) garden. It is another mountain species (from Cyprus) and is variable when raised from seed. If the secateurs are used sparingly and carefully, a very desirable, slow-growing specimen can be produced. A little judicious pruning can help produce yet another attractive cedar, Cedrus deodara 'Pendula'. This should be a large, graceful tree; it is invariably encountered as a tumbling mound, and with the timely removal of the few ascending branches this form can be maintained. The cedar of Lebanon has at least one good dwarf offspring. This is C. libani 'Comte de Dijon' which, in the course of time, grows into a stocky shrub with a height of cjftfjm) or so and a 6ft(2m) spread. the genus as a whole, then C. lawsoniana certainly ranks as the most prolific I of any coniferous species and, for that matter, any hardy tree or shrub. The I numerous cultivars have originated as seedling mutations and to a lesser I extent as branch sports. The results are extremely variable; dwarfs of 12 to II 1501(30 to 38cm) are known and great trees of 7511(22.5111) or so and, oil course, every height in between. While many of these are very good there 1 are legions of stereotyped, rather ordinary forms, and a degree of discretion is needed when deciding which to grow. Let us consider first the tall cultivars of C. lawsoniana-those with an I ultimate height of at least 6ft(2m) and a maximum of 40 to 5oft(i2 to 15m) I, after many years. Golden foliage is, quite rightly, much in demand, and 1 there are numerous cultivars with such colouring to choose from. The I following are among the finest: 'Golden Wonder'; 'Hillieri', slower-growing I than some; 'Lanei', a very pretty and reliable small tree; 'Lutea'; 'Naberi', a I most attractive form with a mixture of sulphur-yellow and blue foliage; I 'Smithii'; 'Stewartii', totally reliable; and the more recently introduced I 'Winston Churchill'. A cultivar with a different form, 'Westermanii', is a I densely branched golden type with pendent branchlets.
