DESCRIPTIVE LIST OF FLOWERS. 239 
If required to grow in thick clumps, they should not be 
often moved, and then with great care, pressing the earth 
close to their roots; a strong, rich, loamy soil is best for 
them; seed for varieties and double flowers should be 
sown in July or August, or as soon as ripe—some say the 
transplanting should take place in August; I am of a dif 
ferent opinion, and think it should take place as soon as 
the flowering is over; in August the blossoms for the en- 
suing spring are forming at the base of the foliage, and to 
check this operation would destroy the flowers, whereas, 
moving in May only endangers the ripening of the seed 
which is not wanted. 
Double Hepaticas in pots are sold in large quantities 
by the gardeners in England, and from the absence of 
foliage the pot appears entirely filled with flowers. 
The double white variety is considered rare.

most gardens. It is a biennial or imperfect perennial, 
three to four feet high, easily raised from seeds, producing 
the second year flowers of various shades, from pure white 
to purple, on long spikes; in May and June. Fine va- 
rieties may be perpetuated by divisions of the root, or by 
cuttings. The double varieties of this flower are superb, 
and highly esteemed for their fragrance and beauty. 
There is a purple and white variety, both very double, 
forming a spike about one foot high. It was known in 
Gerarde’s time, and cultivated by him in 1597. He re-
