Bamboo! amboos are members of the grass family, the Poaceae still used for construction, scaffolding, flooring and indeed or the older wider clan, the Gramineae.. For centuries for utensils and wonderful artefacts. Of course they are at Bin Asia, where most kinds originate, they have been their most beautiful when used in their natural, living form held in high regard and used both for aesthetic and practical as plants. Elegant and distinctive, they rarely compete with purposes. They are hardy and evergreen and can be grown other plants. Because they are grasses, they share with their in most soil types. There are over a thousand species ranging smaller relatives the quality of movement, and that wonderful in size from dwarf varieties to towering giants. Bamboos are swishing sound. Their delicate-looking leaves and attractive canes make a pleasing contrast to most other types of plants. Part of their charm is their versatility. In the classic perennial border or the mixed border of shrubs and perennials, bamboos can be used to add evergreen structure to the composition. Use them behind other plants to form a quiet green backdrop, or repeat them throughout the border to make vertical accents, in the same way that conifers are sometimes used. Phyllostachys and fargesia varieties are especially suited to this, and are far more interesting than static conifers. To heighten a tropical look, bamboos can be mixed with exotic, medium- sized trees such as snakebark maple, paulownia and catalpa or with evergreen, broad-leaved and coniferous types like hoheria, eucryphia, schefflera, Himalayan pine and the lovely Chinese fir Cunninghamia lanceolata. Even in a small garden a wonderful miniature woodland can be created with just a couple of trees and some bamboos. Herbaceous plants and grasses can also be used as companion plants, including Reineckia carnea, Persicaria nepalensis, epimedium, vincas, the grass Hakonechloa macra, the three sedges Carex morrowii ‘Fisher’s Form’, Carex umbrosa subsp. sabynensis ‘Thinny Thin’, and spreading perennial flowers Euphorbia cyparissias, Va ncouveria hexandra, Fragaria chiloense ‘Chaval’ and Fargesia dracocephala, F. jiuzhaigou, F. nitida If you have the space, a dramatic and Waldsteinia geoides. and F. robusta can be clipped into hedges romantic way of growing bamboo is in a grove.

Phyllostachys nigra ‘Punctata’, P. aureosulcata ‘Aureocaulis’ and Thamnocalamus spathiflorus ‘Aristatus’ come to mind. Bamboos look very elegant in pots and tubs. They need watering and feeding regularly to ensure that they never dry out. Containerised bamboos are tailor- made for the smaller garden, including urban balconies and courtyards. Suitable ones include Fargesia rufa, F. scabrida and F. murieliae ‘Simba’. Many of the dwarf and smaller bamboos are superb for groundcover and soon make a dense, weed-suppressing covering of shapely, evergreen leaves. Try, for instance, Pleioblastus chino ‘Elegantissima’, ‘Tsuboi’ and Shibateaea kumasaca. Bamboos are one of the very best plants for stabilizing soil on steep slopes and river banks, especially if they are watered regularly while being established. Sasaella mas ‘Albostriata’, Sasa tsuboiana and S. veitchii are excellent for this purpose. I am often asked what my favourite rare bamboo is. There are many. I particularly like Borinda albocerea for its blue dewy young canes; B. nujiangensis for its graceful foliage; Chusquea gigantea for being an impressive giant; Chimonobambusa Medium bamboos Chimonobambusa Fargesia Fargesia rufa quadrangularis dracocephala Very rare, hardier Square-shaped Very hardy from the than most other canes.
