SUMMER-FLOWERING HARDY VINES 121 
growers, and: all the pruning that is necessary is 
the removal of any very poor shoots and of 
about one quarter of the previous season’s growth 
in early spring. This will give several good, 
strong shoots for flowering from each shoot cut. 
CLEMATIS THAT FLOWERS ON RIPENED WOOD 
The varieties mentioned below flower on 
mature wood and should be pruned lightly. 
After flowering, remove all very thin, weak 
shoots; that is all that will be necessary. The 
best and most popular of the double-flowered 
sort is Duchess of Edinburgh. This is a good, 
free grower and the double white flowers are 
produced with great freedom in midsunimer; 
another good double white is Snowdrift. A good 
double blue is Countess of Lovelace, and Louis 
van Houtte is a nice shade of rosy white. Among 
the singles, the best are C. cerulea var. Standisht, 
a good, light, purple; Miss Bateman, a good, pure 
white; C. florida, white, barred with purple; and 
C. florida var. bicolor, a variety with purple 
predominating. 
I would not advise any one to grow those 
listed here as flowering on old wood, as a good, 
heavy freezing causes the loss of one season’s 
flowers. Duchess of Edinburgh is very hardy
