266 PLANTING THE ORNAMENTAL GROUNDS 



and white-flowered varieties. A leaf climber. Sow in 

 March, in a temperature of 60. 



SWEET PEAS, H. 4 feet or more. Flowers pink, scarlet, 

 purple, blue, white and yellow, of various shades ; fragrant. 

 Useful for cutting and for low screens. The Sweet Pea has 

 been much improved during the last few years, and has 

 become one of the most popular flowers. It delights in a 

 heavy, though deep and rich, stiff loam. For early spring 

 bloom, sow the seed in the fall, 4 or 5 inches deep, giving 

 them a dry situation. In the spring it is well to make 

 several sowings at intervals, beginning as soon as the frost 

 is out of the ground. The other sowings may be at inter- 

 vals of two or three weeks till June. A successful method 

 is to sow them in trenches about 6 inches deep, covering 

 them, at first, with only one inch of soil. As the plants 

 grow the trench is filled up, an inch at a time, till full. 

 When the trench is about full they should be copiously 

 watered. Provide a support trellis of cords. Brush, as for 

 common peas, also answers. The more the flowers are 

 cut and used, the better it is for the plants. Keeping the 

 pods picked off, as they begin to grow, will prolong and 

 promote flowering. A little bone-meal worked into the sur- 

 face of the soil, among the plants, also has a good effect. 

 Varieties of the Sweet Pea have become very numerous, and 

 the list changes from year to year. (See writings of Hutch- 

 ins, and Cornell Bulletins 111 and 127.) 



PROP^EOLUM MAJUS, Hh. Well known, commonly under the 

 name of Nasturtiums. Flowers buff, pink, orange and scar- 

 let. 10 6r 12 feet. T. peregrinum is the "Canary Bird 

 Flower," and is of more delicate appearance than the 

 ordinary kinds. Flowers pale yellow, fringed. Leaves pal- 

 mately lobed. Leaf climbers. Sow the Tropa3olums, espe- 

 cially T. peregrinum, if possible, in March, in a tempera- 

 ture of 55 to 60. They may also be sown in the garden 

 where they are to grow, when it is safe. Give them 

 rich, light soil.
