DECIDUOUS TREES 187 



our yards are full of it. This is an unfortunate mistake, for the 

 common English hawthorn is white and single. All the red and 

 double hawthorns have come from a wholly different species 

 (Crate gus monogyna), although hundreds of nursery catalogues 

 still indicate that they were derived from Cratagus Oxyacantha 

 an immortal error. You do not see double red hawthorns every- 

 where in England because double flowers and unnatural colours 

 are not considered suitable for lawns. The principle has been 

 well stated by our great American landscape designer, Mr. Warren 

 H. Manning: Horticultural forms originated in the garden; they 

 should be restricted to it, and not allowed to dominate the 

 landscape. The showy thing we do is to put pink dogwood 

 and Bechtel's flowering crab on the lawn. The refined 

 thing is to plant white dogwood on the lawn or pink dogwood 

 in the garden. 



I did not see any flowering effects with trees that struck me 

 as particularly English. I believe that we can get the equivalent of 

 their hawthorn with our native species, but not with the European. 

 Our strong card, however, is our native dogwood. We can grow 

 magnolias quite as well, and our western catalpa (see plate 69) 

 is suitable for lawns, but until the day of public spraying comes we 

 should go slow on everything of the rose tribe, because these 

 plants are subject to San Jose scale. I refer to Prunus and Pyrus, 

 which include the flowering cherries, plums, peaches, apples, pears, 

 and quinces.* 



THE COLOURED FOLIAGE EFFECT 



Fortunately flowering trees are showy, as a rule, only when 

 in bloom. Otherwise they would get stale, like a bed of Baby 

 Rambler rose or any other "ever-blooming" bore. But purple
