If seed is not available from within a preferred local seed zone, the next choice should be from among stands of good form and vigour growing at similar elevations in the same ‘region of provenance’. Historical descriptors Historical descriptors are important in Britain because of the scale on which native vegetation has been destroyed and species have been moved, being planted often many hundreds of miles from their original seed source. 1 27 Continued. The terms ‘authochthonous’, ‘indigenous’, ‘native’, ‘alien’ and ‘naturalised’ may each be used to describe an aspect of the history of the seed source.
They also give a relatively uncritical indication of commonly available plants, and thus are limited in their value in plant selection. Many nursery catalogues have selection lists for plants suitable for a wide variety of site conditions. These are usually based on data for gardens and are often helpful in drawing up initial lists of plants suitable for a site but they may not be a reliable guide to the plant’s overall performance in landscape conditions. Selection lists are increasingly common with plant software packages, and these offer the best possibilities for bringing together plant selection and essential data on the plants themselves in a convenient form.
There is usually an assumption by clients, specifiers, suppliers and contractors, that there will be expensive soil amelioration and that the job of the landscape architect and amenity horticulturist is to accommodate whatever plant material the nursery produces. This is a serious distortion of the professional responsibility of these practitioners. Even greenfield sites vary greatly, with soil from clays to coarse sands. It is the handling of these soils through the site development process which is more important than soil amelioration.
