FOXGLOVE.

more plants are required, or cuttings of the sturdy 
slioots or roots may be inserted in sandy soil, and kept 
close for a time in a frame. Other species of Dicentra, 
not so showy as D. spectabilis, are canadensis (white) ; 
chrysantlia (yellow) ; cucullaria (white and yellow) ; 
eximia (reddish-purple) ; formosa (red) ; and thalictri- 
folia (yellow and red). 
DICTAMNUS Fraxinella ( Fraxinella ; Dittany ; 
Burning Bush). — This remarkable plant grows 1 to 2 
feet high. Its leaves are composed of 4 or 5 pairs of 
serrated leaflets, and from May to July its pale lilac- 
rose blossoms, distinctly veined and feathered with 
purple, are borne in erect racemes well above the 
foliage. The variety alba is distinguished by its white 
flower. The plant has been called the “ Burning Bush,” 
owing to the fact that the resinous secretion from the 
stems is often capable of being ignited by a match, and 
may be seen to burn on a dark night, at the same time 
emitting a strong- and agreeable odour. There is a 
bold variety called Caucasians, which attains a height 
of 4 feet, and has a deep reddish blossom. Planted in 
a rich and well-drained sandy soil, the Fraxinella will 
grow well for years. A good dressing of well-decayed 
manure each winter will be beneficial to the roots. 
New plants may be obtained from pieces of the root 
about 2 inches long, inserted in gentle heat in spring ; 
by careful division of the rootstocks ; or by sowing the 
seeds (which germinate slowly) when ripe in a cold 
frame.
