cuttings IniLy be taken in aut,umn, and be treated in about the

from setalls sown in pans or boxes in spring.
Dewberry (Rubus spetcies). KONNVV.
Seeds arc han(llc(I in the saner way a,s blackberry seeds. Increased
by la>*crs an(l, like the t)lackberr>-, root-cuttings and canetips.
J,ayers art rlliltlc simply by covering the decumbent canes
at the joint.+ hut, this method is now lit,tle used. The tips root
freely, as in the \,li~ck(~ap raspbcrrics, and it is from these that the
commcrciitl tlewbt2q. plants ure mostly grown. See Blackberry.
Dianthus (Carnation. Pink. Sweet M?lliam). Caryophyh~~.
Annllnls ,znti pmvnnials, all tA:tsily grown from seeds. The
annual kimls tlrr sometimes started indoors ; but usually the seeds
are sown wli~~ro the PliilltS are to remain. Best results are to be
cspectrvl in most spc&s when new plants of tht perennial kinds
arc grown from seeds every two or three years, as strong plants are
obtained and the beds are kept clear of grass. Plants bloom the
second year from seed. Old plants may be divided, if vigorous.

propagate readily 13~ the undrrground parts - D. Czrcullaria by
