At Trowell garden centre we have a spectacular range of grasses and bamboo plants. Bamboo (Phyllostachys bissetii) Deepest green stems. Hardy and dense which makes it suitable even for a thick hedge or screen. Grow in containers, or plant in the border with a barrier around the roots to restrict the plants spread. Grass. Festuca Glauca Intense Blue. An evergreen with Silver Blue foliage which forms in a dense mound. The strongest blue of all grasses which makes an ideal for a container, borders or rock garden. Produces flower spikes in June.
