Trees 147 



CATALPA (Catalpa speciosa). 50 feet. White tubular flowers in large, 

 showy panicles. June. Quick growing, with clean, furrowed 

 bark and large, heart-shaped leaves. Hardy wherever apples 

 grow. Flowers after horse chestnut. The long seed pods, looking 

 like pencils, scatter seeds in winter. Not so showy as C. bignoniodes, 

 but a better-habited tree. Leafs out late. 



CHERRY, FLOWERING (Prunus avium and Cerasus hortensis fl. />/.). 

 20 feet. White and pink; flowers an inch and a half across in 

 clusters. Among the most graceful of the second-early flow- 

 ering trees, the foliage beginning to develop as the flowers 

 burst open. Will thrive under conditions that suit the fruiting 

 peach or cherry. Double varieties, resembling little roses, last 

 longer than the singles. 



CHESTNUT, HORSE (JEsculus Hippocastanum). 90 feet. Covered with 

 pyramids of flowers in June. Big varnished winter buds; tent-like 

 leaves. Always dropping scales, flowers, fruit, or rusty leaves. 

 Too dense for streets, and an untidy tree on trim lawns. 



CRAB, BECHTEL'S (Pyrus loensis, var. fl. pi.). 30 feet. Pink. May. 

 Best of double-flowered ornamental apples; flowers 2 inches across. 

 When out of flower looks like an ordinary crab. Needs as much 



spraying as fruit trees. , FLOWERING (P. floribunda). 15 



feet. May. Most floriferous, early flowering small tree, or 

 sometimes a large shrub. The arching branches are strings of 

 rose-coloured flowers, seen with leaves. Plant in masses against 

 dark background of taller trees. Fruits make good jelly. Spray 

 for scale and woolly aphis. For San Jose scale the surest remedy 

 is spraying with the lime-sulphur mixture prepared by mixing 15 

 to 25 pounds of unslacked lime, 15 pounds of sulphur, and 50 gallons 

 of water, combining with heat and spraying on the plants imme- 

 diately. More convenient, but a little less efficacious, are special 

 preparations of lime-sulphur and of miscible oils, which are merely 

 diluted with water and are then ready for use. Several special 

 preparations of this character are offered under proprietary trade 

 names; they are practically the same. For all ordinary scales, the 

 whale-oil soap solution is satisfactory. Use one to two pounds of 

 the soap to one gallon of hot water. 



rcuMBER TREE (Magnolia acuminata). One of the best pyramidal 

 trees for lawns. (See MAGNOLIA.)
