spring. Increased by seeds sown outdoors in April, or division 
of the roots in autumn or spring. 
Jasione (Sheep's Scabious). — Two species of this genus 
are sometimes grown in gardens, viz., J. montana, a native 
annual growing 12 to i8in. high and bearing lilac-blue flowers 
in summer ; and J. perennis, a perennial species from W. 
Europe, growing 12 to i8in. high and bearing blue flowers in 
summer. They belong to the Harebell order (Campanulaceae). 
Both will succeed in good ordinary soil, in sunny borders, or 
on a rockery. Sow seeds of the annual species where required 
to grow in April. The perennial species may be planted in 
autumn or spring. The latter is best reared from seed ; it 
does not increase readily any other way. 
Jeffersonia. (Twin-leaf). — J. binata (Syn. J. diphylla) is 
a very pretty dwarf herbaceous perennial, growing 6in. high 
and bearing solitary white flowers in early spring. It is a 
native of the United States and belongs to the Barberry 
order (Berberidaceae). This interesting little plant should be 
grown in peat and leaf-mould in a moist and shady nook of 
the rockery, or on the margin of a bed of peat-loving shrubs. 
Plant in October or March. Increased by division of the 
root-stocks in September ; also by seeds sown in sandy peat in 
a cold frame.

grassy leaves and scarlet or yellow flowers borne on dense 
spikes. An exceedingly handsome and showy genus of hardy 
plants. Besides the species and varieties there are also several 
very pretty hybrids. The best known species are : K. aloides 
(Syn. K. uvaria), 3 to 4ft.; flowers coral-red to orange; Sept,

good forms of it, namely, glaucescens, orange-red ; grandi- 
flora, scarlet and yellow ; prsecox, flowering in May; Saundersi, 
orange-scarlet ; and serotina, flowering in October. K. Bur- 
chellii has a purple spotted stem and scarlet and yellow flowers 
tipped with green ; flowers in summer. K. carnosa is a dwarf 
species, growing a foot high, and bearing apricot-coloured 
flowers with yellow anthers in September. K. caulescens has 
reddish-salmon flowers, borne in dense heads on stems 4 to 
5ft. high in June or July. K. carnosa grows 1 to 2ft. high,
