112 LANDSCAPE GARDENING. 



Sweet Gum. — This tree is especially suitable to the 

 southern states, where, in artistic effect, it takes the 

 place of the Sugar maple in the north. Where it suc- 

 ceeds well it may be planted in masses of almost any size. 



Sycamore, Plane tree or Button wood. — The Amer- 

 ican sycamore is one of the very finest street trees we 

 have, as one will readily believe after seeing it on the 

 Capitol grounds at Washington. It is also useful in 

 general park composition, tlie striking color and texture 

 of its foliage marking it for special notice. It is not 

 hardy north of Vermont, and not at its best north of 

 Pennsylvania. 



Thorn Trees. — The various species of the genus 

 Crataegus make fine additions to lawn plantings, their 

 effect being usually somewhat picturesque. Their small 

 size adapts them to certain positions. Among the best 

 native species may be named Cratcegus crus-galU, 0, 

 tomentosa, and C. coccinea. The English hawthorn, C, 

 oxyacantha, is sometimes planted in this country with 

 fair success. 



Tulip Tree, Liriodendron TtiUpifera. — This is a 

 good tree for situations where something large is required. 

 It may be massed in any quantity. Prefers good soil. 



Walnut. — The common Black walnut makes a fine 

 tree, though it is slow of growth. The Japanese walnuts 

 may sometimes be planted to advantage. The common 

 l)utternut seldom makes a good tree, but it has charac- 

 teristic foliage which makes it useful for planting with 

 other trees. 



Willow. — Many of the willows are useful, especially 

 on low, moist land. The best are Royal willow, Salix 

 regalis, the Shining willow, S. lucida^ the Laurel-leaved 

 willow, 8. laurifolia, and the Golden willow, S. vittelina 

 aurea. The Babylon willow is good in spite of its 

 weeping habit. In general, weeping willows are to be 

 avoided, unless an exception be made for cemeteries.
