Box - Notes

The usefulness of this evergreen was seen in Chapters 9. 16. and 23., while in Chapter 24. its value as a hedge plant was shown. The garden forms of Buxus sempervirens, such as argentea and Handsworthiensis, are dense evergreens that will thrive in almost any soil. They have an aromatic odour. The fact that Box will bear clipping, and is long-lived, makes it no mean rival for the Yew, with those who like formal bushes and topiary. See Chapter 23. Suffruticosa is the form used for low edgings.

Bramble - Notes

See Rubus.

Bridgesia Spicata - Notes

See Ercilla.

Broom - Notes

Reference to the Brooms was made in Chapter 9., also in Chapter 19., where some of the best Cytisuses and Genistas are named. The Butcher's Broom is Ruscus aculeatus. See Chapter 16., also Cytisus and Section A.

Broussonetia - Notes

A small genus of deciduous Japanese trees, of which only one species, papyrifera, is much grown. Dissecta (syn. laciniata) and cucullata are forms of it. The foliage is handsome, and they are worth growing in a large collection of shrubs, but a sheltered place must be provided, as they are none too hardy. Ordinary soil.
