Planting

Exposed Coastal Sites Planting List. It can be really tricky to find plants that will contend with very exposed sites. The combination of wind and salt can be disastrous, and any shelter that can be created will more than pay for itself in protecting the plants. However, there are times when its not possible or practical to create a shelter belt, so here are some of the plants that stand a chance and will give colour and most are generally drought-tolerant also. Armeria maritima - Sea Pink or Thrift. Commonly found on the cliffs, is an excellent rock garden plant with dainty pink flowers. In the wild the flowers are a paler pink, but brighter shades are available on cultivars. Carpobrotus edulis -The Hottentot Fig -Flowers in May and June, likes lots of space to ramble about in hot, open spaces. Looks particularly good cascading down walls and slopes. Survives very well close to the sea, but will not withstand sub-zero temperatures for any length of time. Crocosmia Lucifer - produces clumps of iris-like foliage - with hot red flowers from mid to late summer. Good structural plant that looks good against Canna Wyoming and Dahlia Grenadier. Prefers a well drained soil in full sun or partial shade with a well drained soil, and tolerates a windy situation. Erigeron glaucus - low growing perennial with daisy like purple flowers that bloom for a long period from summer through autumn - great nectar plant for butterlies. Deadhead as needed for a prolonged showing. Eryngium planum - Sea Holly is a great plant for coastal areas, as well as rock gardens. It flowers in mid-late summer in a profusion of small steely blue flowers and is happy in a well drained soil with full exposure to the sun. Its roots were once pulped, sugared and sold as sweets. Osteospermum - Tresco Purple - has a mound forming habit that spreads well, with dark purple daisy style flowers. Does well in exposed, well-drained position. Deadhead for an extended display. Flowers in late summer through autumn and makes great ground cover. Sedum - spectabile - the succulent foliage hosts tightly packed head of green buds that open into small pink flowers from late summer through autumn. Very attractive to butterflies. Is a hardy plant that thrives in full sun an a well drained, light and sandy soil.
  Cotoneaster horizontalis is a hardy shrub that flowers in late spring and early summer, the has attractive berries and leaf colours in autumn. It will grow to about half a metre high with a spread of 1.8 metres in full sun, or partial shade, in a well drained soil.     Eleagnus pungens variegata - can handle full sun or part shade and is very hardy. It likes a well- drained, light soil and can grow to a height of 4 metres with a similar spread. It will flower in late autumn and is a vigorous, spreading shrub. The white flowers are very small, but highly scented.       Eleagnus ebbingei "Limelight" has very similar characteristics to the one above. It will need at least some sun to keep the variegation and likes a fertile, well drained soil. It's hardy with silver-cream coloured, strongly scented flowers and a height and spread of up to 3 metres.
  Escallonia rubra "Macrantha" is a semi-evergreen bushy shrub that is a fast grower. It flowers in mid to late summer with deep pink - red rose coloured flowers and can grow up to 4 metres height with a 4 metre spread. Average yearly growth is 30- 45 cm and they make a good, coastal hedging by spacing at about 90cm apart, creating a hedge 2 metres high at a moderate growth rate.       Euonymus japonicus enjoys the coastal situation as it prefers moist conditions rather than dry and cold, although it can handle temperatures down to -5º C (23ºF) It reaches a height and spread of 4 metres by 2 metres, flowering in early summer. It prefers full sun or light shade with a fertile, well-drained soil.     Fuchsia riccartonii - Hardy fuchsia, has an impressive display of dark purple, crimson flowers. It does well on the rainfall and humidity often found by the coast and can be put at the back of a large border, or used as hedging. It likes full sun or partial shade with a well drained soil. It has a possible height of 2.4 metres and a spread of 1.2 metres.
Hebe x franciscana "Blue Gem" is a smaller shrub of 1-2 metres high, that has rich, violet blue flowers that are sweet smelling and very attractive to butterflies and bees. It is very hardy and particularly tolerant of the salt-laden winds that abound the coastal regions. Commonly named "Veronica".
