Aubretia are small and low growing but their colour makes up for it. A spring flowering trailer. It can also be incorporated in a rockery. It prefers drier conditions so drought tolerant. It is attractive to beneficial insects as a bonus too.
Lobelia is usually a summer flowering annual but they are perennial varieties. These will need some maintenance to prevent them from becoming leggy. The upright type L. ‘Starship scarlett’ will need to be cut back and divided to rejuvenate the plant. The bedding trailier will provide you with a cascade of colour until the 1st frost.
Phlox can be mat forming and upright. A hardy perennial that can be divided or propagated from cuttings. P. paniculata is the most common variety with many cultivars ranging from Oranges, Reds, Pinks and Blues. P. subulata is the variety for ground cover/trailing. The plant flowers from different times of the year. Some early summer through to autumn.
Erodium (Storksbill – related to the Geranium) A hardy variety that provides flowers and distinct foliage, very robust and will offer resilient cover. Erodium x variabile ‘Roseum’/ ‘Bishops form’ – a small alpine on its own, it is clump forming but a cluster of them will create a carpet of colour from the beginning of summer to the end.
Bleeding Heart (Dicentra spectabilis) offers pink white flowers in early spring. This plant does prefer a good nutritious base so a humus rich soil is ideal. The whole structure should have some substance. Take note where it is positioned though, its root system being underground but close to the surface. Its storage organ is a Rhizome – it only slightly protrudes. It will not be visible until it resurfaces so digging up can be so easy.
The Serbian Bellflower is excellent cover for the ground, walls and rockeries. C. poscharskyana ‘Blue waterfall’ will provide a trail of colour from early summer to late. It needs little attention and highly effective in encouraging beneficial insects.
