In reply to B,, who inquires for information concerning the Eulalias on page 70 of the Gardener's Monthly for March, I would say that both Eulalia japonica and E. J. zebrina, are perfectly hardy in this latitude with a slight protection of evergreen branches put on about the end of November and taken off about the end of March.
Hydrangea, Thomas Hogg, is rather tender here, it dies to the ground even in mild winters, and in consequence no flowers are produced. It should be taken up, placed in a cool, dry cellar for the winter, and planted out again about the 10th of April or later, according to the weather. It is what we might call a half hardy plant.
