See the discounted rate for quantities above this - also in the online shop.
Similar to the standard Griselinia, but with deeper green and oval glossy foliage, Griselinia Green Horizon is a fast growing evergreen, hardy to at least -10°C to -12oC. It will withstand salt laden winds but not right on the seafront if in a very exposed position – it will need to be positioned several hundred feet from the sea in such cases. In more sheltered or enclosed estuaries like St. Mawes and Falmouth in Cornwall, they will grow quite happily right on the seafront.
For extremely exposed coastal sites like Land’s End, and Lizard Point in Cornwall, we would recommend the tougher Elaeagnus ebbingei or Olearia virgata Laxifolia.
Upright growing, this variety forms a dense hedge that can be trimmed to 6—8ft (or a height of your choice) and a width of only 60cm / 2ft so it won’t take up a large part of your garden. Even a height of 1-2m / 3-6.5ft can look very neat.
It grows 60-90cm / 2-3ft a year if fed with a very good slow release fertiliser like Trevena Cross Fertiliser, with an ultimate height of 6m / 19ft if left untrimmed.
They should be planted 40-90cm / 18inches-3ft apart from one another - although they can be planted further apart if you do not mind waiting longer for them to form a solid hedge. It forms a neat and compact hedge and it can be used as a specimen plant/topiary in the garden.
