The lists given in this chapter cover the more common uses for whichplants are selected. Perennial lists are not given because perenniaplantings succeed according to the skill of the grower in adaptingthem to his location and giving them necessary winter protectionConstant care must be exercised to replace winter losses. Thediscussion in the main part of the foregoing text under the differentlists and groups of plants applies equally well to most of the northernpart of the United States, including Minnesota and adjoiningterritory.
Throughout this region spring planting is preferable to autumn, ifis done early enough, except of course for peonies and irises. In es-pecially dry autumn weather autumn-planted stock is quite likely toprove a total loss. Ordinary shrubs and trees can be moved in theautumn under good conditions and this is also true of locally growconifers moved in September; but other plants, and especially theperennials, should be moved only in the spring. Owing to theseverity of the climate, especially in dry winters, sometimes withoutsnow more than six inches deep, there is little tendency to encourageexperimenting with half-hardy stock and most of the lists given andshort.
