be lifted before frost and stored for the winter 
—a dry cellar is a good place — and it must not 
be planted out before May 20. 
A curious variety that is directly opposite, in 
general habits, to the rest of the ipomozeas is the 
noon-flower (J. linnata). It opens its flowers 
only for a few hours at mid-day, whereas most of 
this family, while requiring the sunlight, usually 
close their flowers when the sun is strongest. 
The flowers of this plant are white with a purple 
centre, and, the roots being tender, they must be 
lifted in fall. Another very tender member of 
the family, which can be treated as an herbaceous 
plant by lifting the tubers in fall and storing them 
for the winter, is the tree ipomoea (J. fistulosa). 
This variety will run up ten feet and become 
literally covered with pinkish-purple flowers. 
For those who do not care to burden themselves 
with lifting tubers and planting them out again in 
spring, I would recommend the man-of-the-earth 
(I. pandurata), a hardy variety which has immense 
tubers that cause the plant to be thus named. 
The flowers are pretty, white, with a purple 
throat, while the plant is in bloom all summer. 
Its kitchen garden relative, the sweet potato 
(I. batatas), is grown for its edible tubers less 
than it should be in the North. Just a word as
