ENCYCLOPEDIA OF GARDENING. 
seed lin. deep in April where plants are required to grow. Remove 
seed pods as they form to ensure free flowering. Dwart kinds: Soil, 
ordiuary, not over rich. Position, sunny or shady borders or beds. 
Sow seeds lin. deep & 3in. apart in lines or masses in April. Thin 
seedlings to 6, 9, or 12in. apart when 3 in high if fine plants are desired. 
Remove seed pods unless seed is required. 
POT CULTURE: Sow sceds }in. deep & 2in. apart in 5-in. pots 
filled with a compost of two parts good mould & one part decayed 
manure in April. Place pots in window or cold frame. Water modc- 
rately at first, freely when in full growth. Apply stimulants occa- 
sionally when in flower. Double varieties propagated by cuttings in 
temp. 55° in spring. Plant outdoors in May or June. May be grown 
in pots in a compost of two parts loam, one part leaf-mould, & little 
sand. Pot in March or Ape. Water freely in summer, moderately 
ae times. Temp., Oct. to March 40° to 50°; March to June 55° to 
65°. 
CULTURE OF T, LOBBIANUM: Sow seeds in light soil in temp. 55° 
in March, harden seedlings off in cold frame in April, & plant out in 
June in sunny position against walls, fences, arbours, or in borders, 
placing tree branches to support the shoots; or outdoors }in. deep in 
April where required to grow. 
Inpoor CutturE: Compost, two parts sandy loam, one part leaf- 
mould or decayed manure & half a part sand. Position, well-drained 
pots or beds, training shoots up rafters, Water moderately Sept. to 
April, freely afterwards. Propagate by cuttings of shoots, 2 to 3 in. 
long, inserted in sandy soil in temp. 55° to 65° in spring. Temp., Sept. 
to March 50° to 60°; March to Sept. 65° to 75°. 
CULTURE OF GREENHOUSE TUBEROUS-ROOTED SPECIES: 
Compost, equal parts turfy loam, leaf-mould, peat, & silver sand. Posi- 
tion, well-drained pots in light, airy greenhouse. Pot, Aug. to Nov. 
Place one tuber only in » pot and bury this about lin. Water very 
little till plants grow freely, then give an abundant supply. Withhold 
water entirely when foliage turns yellow & until growth recommences. 
Apply stimulants occasionally when plants are in flower. Train shoots 
to wire trellis fixed in pots or up ratters. Temp., Nov. to Feb. 40° to 
50°; Feb. to June 55° to 65°. After growth ceases, store pots in cool 
place till potting time. Propagate by seeds sown in light sandy soil 
in temp. 55° to 65° in spring; cuttings of shoots inserted in sandy soil 
in temp. 55° to 65° in spring or summer. 
CULTURE OF HARDY SPECIES: Soil, light sandy loam for T. 
pentaphyllum ; ordinary mould for T. polyphyllum; equal parts loam, 
peat, leaf-mould, & sand for T. speciosum ; poorish mould for T. tubero- 
sum. Position, south wall or fence for T, pentaphyllum; sunny bank 
for T. polyphyllum; shaded wall or hedge facing north for T, specio- 
sum; sunny border for T. tuberosum. Plant T. tuberosum in March 
or April; T. polyphyllum, Aug. to Nov.; T. speciosum & T. pentaphyl- 
lum, Oct. or March. Water freely in dry weather. Mulch with de- 
cayed manure in Oct. Lift tubers of T. tuberosum in Oct., store in 
sand in frost-proof place till March; leave others undisturbed. Pro- 
pagate by seeds sown in loam, leaf-mould, & sand in cold frame in 
April; division of roots at planting time. 
ANNUAL SPECIES: T. aduncum (Syn. T. canariense) ,Canary Creeper, yellow, 
summer, 3 to 10 ft., Peru. Strictly a perennial, hut best grown as an annual;
