A native of Spain, Italy, the South of France, and the Barbary 
States. 
A shrub two to three feet high, with slender tetragonous 
woody branches permanently clothed with white tomentum. 
Petioles very short. Leaves oblong, blunt, entire, twelve to 
eighteen lines long, subcoriaceous, green and glabrous above, 
permanently clothed with a coating of cottony tomentum which 
is usually pure white but sometimes a pale rusty brown. F'lowers 
in lax racemes, the lower whorls in pairs from the axils of the 
upper leaves. Pedicels erecto-patent, tomentose, two to three 
lines long. Calyx a quarter of an inch deep, tomentose like the 
rest of the plant, obconical, cleft about half-way down with 
subequal lanceolate-deltoid teeth. Corolla bright blue, tender, 
declinate, with a very short tube, the lower segment nine to 
twelve lines long, deeply lobed, very concave. Stamens and style 
filiform, nearly equal, forming a conspicuous arch.

This is a very interesting and showy plant, producing an 
abundance of bright lavender-coloured flowers. It requires 
plenty of pot room, and should be grown in rich loam, and 
protected during the winter in a cool greenhouse. It is increased 
by cuttings. Planted near a south wall, where it can have a 
little protection from frost, it will endure our winters.—W. W. S.
