This section of the book is from the Guide To Hardy Fruits And Ornamentals book, by Thomas Joseph Dwyer, published in 1903.
We are all fully aware of the necessity of flowering shrubs in the beautification of the rural home grounds and the great quantities of species of this family we have to select from. having made a careful study of this branch of horticultural work I feel confident that the varieties which I intend to describe and recommend will give entire satisfaction to my readers, no matter in what section of country you may intend to plant. I have been very cautious to select only those varieties that are perfectly hardy and will give good effects whether planted singly or in groups. Let me importune my friends to be more generous in the use of shrubs on the home grounds; they require very little care except an occasional shortening of the branches to infuse new life in the remaining buds, and removing old and decayed wood. When once planted we can have an abundance of bloom annually from Spring until Autumn, providing we make selections that will give us a continuity of flowers. Not so with Herbaceous or bedding plants, which we must continue to plant annually. We will not attempt to group the various sorts but leave this to the judgment of the planter, he being in a better position to determine the desired results.
* How to Plant
-- Dig the holes and plant in the same way as before recommended for the ornamental trees. The Hardy Flowering Shrubs can be planted during the months of March, April and May, in the Spring. Our aim should be, however, to plant them as early as possible, whilst the stock is in dormant condition. You can also plant in the Fall to good advantage during the months of October, November and December. Mulch the ground about the plants with a good, liberal application of stable manure, letting it remain on the ground during the Winter months, and incorporating it in the soil in the early Spring.
* Spirea, Vanhouttii
-- One of the most charming and beautiful of the Spireas. Habit graceful and drooping. Completely covered with panicles of pure white flowers. A handsome sight when in full bloom. We. cannot say to much in praise of this grand shrub which profusely bears beautiful flowers annually under neglect.

-- A beautiful flowering shrub; the flower clusters, which are produced all over the bush, are spherical in form and of the purest white, with beautiful crimped, dark green foliage. There are many other varieties of Snow Ball, but all are susceptible to the attacks of plant vermin, which curl and twist their wood into abnormal shapes, making them undesirable for planting. (Viburnum Plicatum) is free from the ravages of this insect and we recommend it with confidence.
* Forsythia, Suspensa (Weeping Golden Bell).
-- An almost evergreen shrub of sprawling habit, covered in Spring before the leaves appear with handsome yellow flowers. Very conspicuous..

-- There are several varieties of Hydrangea, but we consider the Hydrangea Paniculata Grandiflora the most reliable for outdoor culture; it is perfectly hardy and can be grown successfully in the coldest locations; it bears a profusion of white flowers which change to pink in Autumn; it can be used advantageously for many purposes as single specimens or for grouping; it is also a very desirable hedge plant. We think one of the most enjoyable sights we viewed the past season was a large hedge of Hydrangea P. G. It requires severe pruning in Spring, it can be cut back to the ground if necessary and will bear a profusion of flowers the same season. The Hydrangea makes a fine showing planted in beds in lots of six and upwards; set the plants four feet apart.
* Prunus, Japonica FIore1 albo pleno (Double White Almond)
