P. nii:oszr.s grows readi\)- from root-cutkings, I-‘. ncidus and P. Em-
Mica may be grown from seeds ; the latter also by layers.
Phymatodes. l’nl~~~~diwm.
Spores and division. See Fmhs, page 312.
Physalis (Ground or Winter Cherry. St,rawberry Tomato. Husk
Tomato). Ic;@l~?l~cf'~.
Propagated by se&, sown out,doors or under cover ; perennials
by division of the rhizomes and soft cuttings.
Physocarpus (Ninebark). Kj~scccc~~.
Propagated hy harclwood or greenwood cut,tings and by seeds, as
for spiraea.
Physostegia. Labinfn.
Division of strong c:iumps ma.y be made readily ; also grown from
SW&, a,~ are other herbaceous perennials.
Phyteuma. Cam pan dacm.
Propagated freely by seeds, and division in spring.
Phytolacca (Stoke. Poke), I’h~~to7afcacc~.
Propagated by means of seeds, or by division of the thick roots,
usually the former.
Picea (Spruce). /‘iltnc’fff.
Propagated l-):7 seeds, sometimes h~v layers, sometimes by grafts ;
also by cuttings of recent. wood. Seedlings must be shaded the first
year. The sp&es are easily grafted. P. cxcdsn (Norway spruce)
or P. canadcnsis (rtlh~) makes a good stock ; the veneer-graft,
under glass, in winter, succeeds better than any method of outdoor
work practicable in our climate ; if t,he graft is inserted near the
base in young plants, it is quite possible to obtain them on their
own roots after a few transplantings, 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 ma,y st,art from the stem.
The balsam fir is- a.lso a good stock for flat-leaved species. See
A him.
Pieris. lhkY?E.
Propagation by seeds and layers and the evergreen kinds by
cuttings of almost, ripened wood in August under glms, kept
