A gay little plant, forming one more addition to the large 
genus Lupinus. The flowers are rich bright lilac, enlivened 
by a yellow spot on the white centre of the vexillum. In 
number the leaflets vary from 5 to 9. The seeds, by which 
Lupines may be distinguished more accurately than by the 
ordinary marks employed by Botanists, are oblong, smooth, 
and mottled with grey of different tints. Fig. 3, represents 
one of them; 2, is a ripe pod; and 1, is the ovary and style. 
It is a half hardy biennial, growing from one to two feet 
high, and flowering a great part of the summer and autumn. 
Like other Lupines it requires a strong rich soil, and although 
a half shrubby biennial, is best treated as an annual. 
The seeds should be sown about the beginning of March, 
in pans filled with a loamy soil, and when large enough should 
be potted, placing three plants in a small pot; afterwards, 
when the danger of the late spring frosts is over, they may be 
planted out in the open border. The seeds may also be sown 
in the open border about the middle of April, but then the 
January, 1844. B
