THORNDALE SUB-ZERO ENGLISH IVY 
These evergreen Sub-Zero English Ivies are the decendants of a remarkably hardy Ivy 
which has withstood twenty Chicago winters without protection, Even this winter, 
when temperatures dropped to 26° below zero here in Woodstock, the Thorndale Sub- 
Zero English Ivy came through in fine shape, 
More than thirty "Ivy Generations! later, these great-great-great-grandchildren are 
continuing to display the same uncommon hardiness as the original plant. 
They have been tested under all sorts of growing conditions and they have continued 
to prosper where all other Ivies have failed, 
HARDY BALTIC IVY 
This hardy Ivy has somewhat smaller leaves than the Thorndale Ivy and also finer 
branches. It is easily cultivated, and, like the Thorndale Sub-Zero English Ivy, 
will grow in a wide variety of soils, 
Baltic Ivies will also climb, of course. It is well to plant them on the north or 
east sides of houses since they are subject to winter leaf burn. 
If planted as ground cover, the soil should be well prepared, Manure, (not fresh), 
spaded into the ground or soil mixed with peet moss, leaf mold, or compost, will 
help to give the plants a good start. Once they are established, they require 
little care for they are relatively free from insects and diseases, 
PLANTING INSTRUCTIONS 
~All Ivies prefer shady or semi-shady locations, such as under trees and shrubs, or 
@s ground cover along the north or east side of houses. However, they will prosper 
in open situations provided the ground is kept moist. 
To give these Ivies the best possible start, we suggest that you plant them 
according to the following directions...
