142 PAMILTAR GARDEN FLOWERS. 
This “Henderson’s clematis” is a fine climber, running ten 
to fifteen feet, and producing an abundant display of large 
handsome flowers of a purplish-blue colour. One of the 
grandest natural species (as distinguished from garden 
varieties) is Clematis lanuginosa. This produces flowers of 
immense size, the colour a soft lavender-blue or lilac- 
tinted grey, which is enriched with a tuft of reddish 
anthers. ‘This plant does not flower so freely or so con- 
tinuously as to satisfy the exigent florists, and the question 
has arisen, What can we do to improve it ? 
In the year 1858 Mr. George Jackman, of the Woking 
Nurseries, made an endeavour to meet that question, and 
extraordinary results have followed therefrom. He crossed 
C. lanuginosa with C. Hendersoni, and obtained two new 
and splendid varieties, producing flowers remarkable for 
their richness of colouring, their excessive profusion, and 
their long continuance. Rarely in the history of practical 
floriculture have we seen so great a triumph accomplished 
at one bound. The two new sorts were named respec- 
tively C. Jackmannt and C. rubro-violacea. The first- 
named is certainly one of the most popular garden flowers 
known. The other, of which we present a faithful 
portrait, is less popular, but not less worthy of esteem ; 
for its flowers are exquisitely coloured and lustrous, and 
are produced in the most prodigal profusion—in fact, 
a verandah well clothed with this clematis will preseut 
during the later summer months a display of colour of 
the most surprising and delightful character. 
These two varieties have in their turn produced in- 
numerable seedlings; and from other crosses, effected by 
various cultivators, there have been secured valuable 
additions to the list of garden forms of this hardy and
