Phyllocladus, Thalamia (Celery-leaved Pine-Tree). Coniferce 

 Cuttings of the ripened shoots under glass, in spring. 

 When the cuttings begin callusing, give mild bottom heat. 



Physalis (Ground or Winter Cherry, Strawberry Tomato, Husk 



Tomato). Solanacece. 



Seeds, sown out-doors or under cover. Perennials by 

 division and growing cuttings. 



Physianthus, Schubertia. Asclepiadece. 



Seeds, usually started in heat. Cuttings of firm shoots 

 usually side shoots, under glass. 



Physochlaina. Solanacetz. 



Seeds. Cuttings of soft wood. 

 Phyteuma, Rapunculus (Horned Rampion). Campanulacece 



Easily increased by seeds or by divisions, in spring. 

 Phytolacca (Spoke, Skoke, Poke). Phytolaccacece. 



May be propagated by means of seeds, or by divisions. 

 Picea. Coniferce. 



Propagated by seeds, sometimes by layers, or grafts. P. 

 excelsa (Norway spruce) makes a good stock ; the veneer 

 graft, under glass, in winter, succeeds better than any 

 method of out-door work practicable in our climate ; if the 

 graft is inserted near the base in young plants, it is quite pos- 

 sible to obtain them on their own roots after a few trans- 

 plantings. Side-shoots can be used as cions, and if started 

 in time will furnish good leaders ; sometimes a leader is 

 developed more rapidly by bending the plant over at nearly 

 a right-angle, when a stout bud may start from the stem
