STRAWBERRY GERANIUM STUARTIA. 3^3 



strong enough for setting are obtained in August and Sep- 

 tember of the same year in which they start. Ordinarily, 

 the runners will take root without artificial aid; but in 

 hard soils, or with new or scarce varieties, the joints are 

 sometimes held down with a pebble or bit of earth. New 

 varieties are often propagated throughout the season from 

 plants which are highly cultivated, and which are not 

 allowed to fruit. Very strong plants are obtained by 

 growing them in pots. A 3-inch pot is sunk below the 

 runner, and the joint is held upon it by a stone or clod. 

 The runner is then pinched off, to prevent further growth, 

 and to throw all its energy into the one plant. The pot 

 should be filled with soft, rich earth. Shouldered pots are 

 best, because they can be raised more easily than others, 

 by catching the spade or trowel under the shoulder. The 

 plants will fill the pots in three or four weeks, if the 

 weather is favorable. Old tin fruit cans, which have been 

 heated to remove the bottoms, can also be used. 



Cuttings of the tips of runners are sometimes made and 

 handled in a frame, as an additional means of rapidly 

 increasing new kinds. These cuttings are really the cast- 

 away tips left from the headings-in or checking of the 

 runners. 



Strawberry Geranium. See Saxifraga. 

 Strawberry Tree. See Arbutus. 



Strelitzia (Bird of Paradise Flower, Bird's-tongue Flower). 



Scitaminea. 



Increased by seeds, which should be sown in light soil, 

 and the pots plunged in moist bottom heat. Also in- 

 creased by suckers and by division of the old plants. 



Streptocarpus (Cape Primrose). Gesneracece. 

 Readily propagated by seeds or by division. 



Strobilantb.es, including Goldfussia (Cone Head). Acan- 



thacece. 

 Seeds. Cuttings, in any light soil under glass, in heat. 



Struthiola. Thymel<zace<z. 



Seeds, when obtainable. Cuttings in sand under a 

 frame. 

 Stuartia. Ternstrcemiaceez . 



May be increased by seeds and layers, or by means of 

 ripened cuttings, inserted in sand under a hand-glass. 

 Seeds are oftenest used, where obtainable.
