PRACTICAL PLANT PROPAGATION 



Achillea Ptarmica (The Pearl) 

 Anchusa italica 

 Anemone japonica 

 Bouvardia Humboldtii. In 



Spring. Give bottom heat. 



Cover with sand, placing 



sphagnum on the sand until 



growth starts. 

 Campanula pyramidalis 

 Ceratostigma plumbagin- 



oides (Plumbago Larpentae) 

 Coronilla varia 

 Eryngium (perennial species) 

 Euphorbia corollata 



Section I. The smaller and more delicate rooted sorts are cut 

 into lengths of one to two inches, and scattered over the surface of 

 the soil, after which they are covered with about a half inch of finely 

 sifted light loam or sand. Cover the flats with newspaper and start 

 cool. Adventitious buds will soon form. When the growths have 

 started a bit, the plantlets should be transplanted to other flats 

 about two to three inches apart each way. 



The following perennials are in this manner propagated: 



Gaillardia (named varieties) 

 Phlox decussata. Cuttings 

 may be taken in September or 

 October and placed in a cold- 

 frame. These give good plants 

 in May; saleable in Fall. 

 Phyllanthus 

 Polygonum 

 Romneya Coulteri 

 Salvia (perennial species) 

 Saponaria 

 Senecio pulcher 

 Stokesia cyanea 

 Verbascum (hybrids) 



Section II. Some other plants, although propagated indoors, are 

 best handled by placing the cuttings perpendicularly in the soil so 

 that the upper end protrudes a half inch. This class of plants usually 

 has fleshier roots than those in the previous group. The follow- 

 ing are so propagated: 



Bocconia cor- Gypsophila 

 data 



Dicentra spec- Helianthus 

 tabilis rigidus 



Dodecatheon 



Meadia Monarda 



Paeonia. Use pieces 3 inches long, 

 planting in beds out of doors in Fall; 

 especially successful with varieties of 

 P. officinalis. 



Papaver. Fleshy root species. Cecil 

 Davies in The Gardener's and Florists' 

 Annual for 1917, writes, "Between 

 August and December is a good time 

 to start the named varieties of Orien- 

 tal Poppies. Obtain strong field- 

 grown plants, cut the roots into 

 lengths of 2 or 3 inches, pot into 

 3-inch pots and place in coldframe 

 for the Winter. Nice plants result

Radish. Such 2-inch pieces of root _ . _,, 



make the best sort of cuttings. atatice 1 nermopsis
