THE FLOWER GARDEN. 
An occasional dose of weak liquid manure will also be beneficial 
when plants are growing- freely. Sometimes clematises die 
suddenly. This is due, as a rule, to imperfect grafting, and 
the result of want of a perfect union between stock and scion. 
Plants reared from layered shoots do not show this defect. 
Clematises are readily increased by seeds sown in sandy 
soil in a cold frame in autumn or spring. The seeds, however, 
take many months to germinate. The hybrids of Coccinea, 
Jackmanii, Lanuginosa, etc. ; also Flammula, montana, etc., 
are among those that may be reared thus. The usual method 
of increase is by grafting in spring on the roots of C. vitalba, 
Viticella and Flammula. Layering the young shoots in summer, 
and removing the rooted layers in October, is an easy method 
of propagation. Plants reared thus are longer lived than 
grafted ones. Propagation by cuttings is another method 
seldom followed. In this case the young shoots are cut up 
into eyes and placed in light soil in a heated propagator in 
March. 
Clianthus (Glory Pea). — C. puniceus, the only species 
suitable for outdoor culture, is a pea-flowered shrub (Ord. 
Leguminosae), a native of New Zealand. It is extensively 
grown as a climber in greenhouses, but in the west and 
southern maritime districts of England and Ireland it flourishes 
exceedlingly well as an outdoor wall plant. In such favoured 
localities the plants grow 15 to 20ft. high and nearly as much 
in width. The flowers are large, borne in bunches, and crimson 
in colour. Of this there is a stronger-growing variety named 
Magnificent, and also a white-flowered one, of which we have 
received fine flowers from Devonshire. The Clianthus requires 
a well-drained sandy loam and a south or west wall, well 
protected from cold winds. Plant in March or April. In- 
creased by seeds sown in light soil in heat in spring ; cuttings 
inserted in sandy soil in spring. 
Cobsea. (Cup and Saucer Flower). — A half-hardy Mexican 
climber, belonging to the Phlox order (Polemoniaceae). C. 
scandens is a well-known greenhouse climber, but seedlings of 
it are often planted outdoors in summer to form temporary 
coverings for trellises, etc. In the south and west it will 
survive the winter outdoors ; in fact, in mild winters plants 
have survived the winter in a London suburban garden. It 
has pleasing green foliage and purplish cup-like flowers, with 
saucer-like lobes. Its chief value is the rapidity of its growth, 
this soon covering a large space. Sow seeds in heat in 
February or March, grow the seedlings on in heat till June, 
then plant outdoors. If a mulch of fern, manure, or ashes
