Derivatives of L3. socnfra~~ are grown frotn the bulbels, that
usually form freely .
Tuberous begonias may be propagat.ed by seeds, cuttings, and
by division of the tubers. They are commonly grown from seeds,
which should be sown early in spring, and the seedlings pricked off
and shifted regula,rly. Cuttings of the young rapidly-growing
shoots, if taken as soon as the plants are 4 to 6 inches high, will
form good tubers by fall. Cuttings made while the plants are in
flower rarely produce tubers of ~nwh value ; B. ix&&& and
B. 17clifrlzil: are particularly likely to fail in this respect. The
cuttings should be L’ to 4 inches in lengt,h, the lower cut being
just, bcncath a joint ; remo1.e one or two of the lowest leaves and
insert singly near the edge of thumb-pots filled with a soil composed
of al)out cc-~~~al parts sa,nd, leaf-mold and loam. Place in a
cool sh;ltlcd position, applying water onl)r to prevent flagging.
IXviding the tubers is an unsat,isfactory met,hod of propagation.
If employed, the tnlxlrs should be cut before active growth begins,
so that each part shall have an eye or crown. They are then
treated as separafe tubers. Begonias which have not been improved
arta most easily and rapidly propagated from seed ; the
named or inlproved varieties are best increased by cuttings.
Belamcanda, including Pardanthus (Blackberry Lill*). Iri&ncc~.
Increased by seeds, division and cutt.ings of Jroung growth. The
blackberry- lily (11. dz.iwmis) propagates readily? by division and by
scccl~, the latter being freely produced.
Bellis (English Daisy). CJomyositcr.
Increa,scd readily by seeds, which should be sewn in early spring.
Also propagated 1)~ division after flowering. Seeds do not always
reproduce the spe&l kind, and choice forms are multiplied by
division.
The was gourd is readily raised from seeds planted after the
weather is warm ; handle same: as for melons.
Benthamia : COW US.
Berberidopsis. Flncourtiaceau.
Multiplied by seeds in spring, by layering in autumn, and by
young greenwood cuttings in spring.
