l88 THE NURSERY LIST. 



Bladder Senna. See Colutea. 

 Blandfordia. Liliacece. 



Propagated by seeds and offsets, or by division of the 

 old plants, which must be done when repotting. 



Blazing Star. See Liatris. 

 Bleeding Heart. See Dicentra. 



Bletia. Orchidacea : 



Propagated by divisions, which should be made after 

 the plants have finished flowering, or previous to their 

 starting into growth. These are terrestrial, and their 

 flat, roundish pseudo-bulbs are usually under ground. 

 They bear division well, especially B. hyacinthina, which 

 may be cut up into pieces consisting of a single pseudo- 

 bulb. (See under Orchids.) 



Blood Flower. See Haemanthus. 



Blood-root. See Sanguinaria and Haemodorum. 



Blueberry. See Vaccinium. 



Blue-eyed Grass. See Sisyrinchium. 



Blumenbachia. Loasacecz. 



Propagated by seeds sown in pots in spring, and placed 

 in a gentle heat. 



Bocconia. Papaveracecz . 



Some species grow well from seed. By young suckers, 

 taken from established plants during summer. Cuttings 

 taken from the axils of the large leaves during early sum- 

 mer push freely, so that they will have plenty of roots 

 before winter sets in. Root cuttings of B. cor data strike 

 freely. 



Boltonia. Composite. 



Increased by divisions of the root in spring. Seeds. 



Bomarea. Amaryllidacece. 



Propagated by seeds, which may be sown in a warm 

 house. Also increased by careful division of the under- 

 ground stem. In making a division, it is necessary to 

 observe that the part taken has some roots by which to 

 live till new ones are formed.
