In the early years of the 20th century the herbaceous border was an essential feature of the larger garden. It was long and narrow with a backcloth of a wall or clipped hedge. Border perennials were used in tiers, with tall-growing varieties at the back and clumps of low-growing plants at the front.
MIXED BORDER The mixed border has taken over from the herbaceous border as the most popular way of growing border perennials. Gone are most of the slavish rules, and the flowering season has been extended by including other types of plants. Like all borders it is designed to be viewed from 2 or 3 sides and not from all angles, and the shape is often irregular and no longer strictly rectangular. The usual pattern is a framework ofand decorative evergreens. and border perennials form large and colourful patches and close to the front a number of pockets are left to be filled with bulbs and .
The island bed is a modern variation of the traditional herbaceous border. Like its illustrious predecessor it is designed for border perennials, with the tallest at the centre and the shortest around the edge. Like all beds it is designed to be seen from all sides and the shape is often irregular.
SPECIMEN PLANT A specimen plant is grown to be admired on its own as distinct from being grouped with other plants – its role is to serve as a focal point. Obviously great care must be taken in itsselection and maintenance, and the usual choice is a shrub or tree. Several border perennials make excellent specimen plants – examples are Agapanthus, Cortaderia and Paeonia.
BED A bed is a planted area which is designed to be viewed from all sides. The flower bed is the traditional home for, , bulbs and hobby plants – the occupants are usually planted (’bedded out’) in autumn for a spring and in late spring for a summer show.
A raised bed is similar in use to an ordinary flower bed but the sides are made up by a retaining wall and the space within filled with free-draining soil. The raised bed is particularly useful where theof the garden soil is poor or where age or infirmity makes stooping by the gardener difficult.
PEAT BED A peat bed is a variation of the raised bed. The retaining wall is made up of peat blocks and the in-fill is ain which the peat content is greater than the soil fraction. An excellent home for lime-hating plants – grow alpines or ferns in the cracks between the blocks.
TUB A useful way of growing showy annuals or bulbs close to the house. Alternatively use it for a bold specimen plant. If you have aor conservatory, tubs can be used for half hardy or tender perennials – the containers are moved indoors in October and brought out again in June. Remember that tubs require regular .
SINK GARDEN A sink garden is made from an old stone sink in which thehole has been covered with perforated zinc and which has been filled with a free-draining . Glazed sinks should have the outer surface covered with a more natural-looking coating. It is used for growing miniature rockery perennials, dwarf conifers and miniature bulbs. PATIO OR PATHWAY A pathway is a hard-surface area which leads somewhere. A doesn’t – it is basically an outdoor extension of the living room. Cracks between the stones can be filled with a variety of mat-forming rockery perennials.
ROCKERY A rockery or rock garden is a planted area devoted to rockery perennials, dwarf conifers and bulbs. Low growing annuals are frequently used to supplement the summer. Ideally it should imitate a natural stone outcrop.
