Marginal Plants for the Garden Pond
`Marginals’ as they are called, are grown on the shelf around the edge of your pond. Although planting containers are generally used, it is wise to construct a lip edge to the ‘shelf’ to retain spiltand prevent eroded soil from silting up the main pool. An edging from several short pieces of smooth, angled batten will provide a satisfactory edging shape. Groups of similar plants tend to be more visually impressive than single plants. Shorter varieties should be planted in the foreground with taller plants taking up the rear. Time spent in drawing up a visual height chart can be rewarding, and you should ensure that you take account of the fully grown size rather than their size when planted.
There is such an abundance of varieties and colours from which to choose and they are so easy and rewarding to grow, that no garden can be complete without some varieties of this dainty and beautiful plant. The following are varieties which will suit the conditions to be found around your garden pool, and of course there are a great many others that would thrive and delight the eye. All do best in a deep rich soil with added humus.
