Ranunculus (Rut tercup. Crowfoot). H~PWWU~CLC~Q.
Propagated by seeds, and by division of the plants in spring.
The thick-rooted species are propagated by the natural division
of the tuberous parts. After flowering and the herbage dies down,
the tuberous roots may be taken up, dried, and kept cool and dry
until spring ; or the plants may be left in the ground where the
winters are not too 5evere.
Raphia. PCilUl clrl’rp.
Propagated by seeds. See Pa.l,ms, page 377.
Raspberry (,R~ztbus st~it~osus, K. ocride~ltal,is, etc.). Rosacea?.
New varieties are originat.ed from seeds, which are washed from
the pulp md sown immediately, or stratified. Bearing plants should
be had the second growing season, or perhaps the third season far
1N0rt11.
The black-cap varieties are grown mostly from root-tips, as
described on page ‘il. If the ground is loose and mellow, the tips
will commonly take root themselves, but on hard ground the tip
rrl;l; have to be held in place by a stone or clod. Some strong-growing
varicxties, as the Gregg, especially in windy localities, have to
be hetd down. Comme&ial growers commonly bury the tips in
early fall. Blackcaps may also be propagated by layers and by
root-cuttings. These cuttings are best handled in warm coldframes
or mild hotbeds, being planted very early in spring. By the time
the weather is settled, they will be large enough to plant in nursery
rows.
The red varieties increase rapidly by means of suckers which
spring from the roots. Better plants are obtained by means of
root-cuttings, however, as described under blackberry (see also
Fig. lo:* set&, cuttings of strong shoots in heat and
divisions of old plants.
