    Griselinia Green Horizon

    £6.95£25.00
    No longer available for sale online - still available to visitors at the garden centre.

    As a guide: 5 litre - 60-90cm high 10 litre - up to 1m high - not currently available online. Please call 01736 763880 or email to enquire. 20 litre - in excess of 160 cm - not currently available online. Please call 01736 763880 or email to enquire. A quick grower, we don't find height of griselinia is really such an important factor when considering the quality of the plant. A decent pot size provides a good indication of plant robustness and bushiness, and in fact we will cut our nursery plants down to encourage bushier growth (rather than a 'leggy' plant). if we feel it necessary.

    Similar to the standard Griselinia, but with darker green, glossy leaves, Griselinia Green Horizon is a fast growing evergreen hedging plant, hardy to at least -10°C to -12°C. It will withstand a coastal position and salt laden winds well but as with the standard and other variations of Griselinia, prefers a more sheltered estuary or inlet like St Mawes or Falmouth in Cornwall. In more exposed locations, Griselinia Green Horizon will need to be positioned several hundred feet from the sea, and for extremely exposed coastal sites like Land’s End, and Lizard Point in Cornwall, we would recommend the tougher Olearia hedging types.
    A per plant discount is available for bulk purchases of Griselinia Green Horizon hedging plants. This discount will be applied in your basket if applicable (begins at 10+ plants).

    Griselinia littoralis is a fast growing evergreen hedging plant with apple green leaves, hardy to at least -10°C. It will withstand salt laden winds on the seafront in sheltered or enclosed estuaries like St. Mawes and Falmouth in Cornwall, but in exposed positions will need to be positioned several hundred feet from the sea.
    For extremely exposed coastal sites like Land’s End, and Lizard Point in Cornwall, we would recommend the tougher Olearia traversii or Olearia virgata Laxifolia over Griselinia littoralis, although Griselinia is a super choice for most locations.

    Echium pininana

    £4.50£9.50
    Echium pininana – this exotic, evergreen plant originates in the Canary Islands and has an unusual appearance with huge hairy, silver leaves. Also evocatively named the Giant’s Vipers Bugloss, it seeds freely after flowering from the very tall spikes of funnel-shaped blue flowers it produces in the summer. (Height 3-5 metres). To thrive it needs full sun and well-drained soil and although it can withstand temperatures as low as minus 5 degrees centigrade, it should be protected from hard frost. It can cause skin irritation. Pictures are for guidance only. Plants available in a one litre pot are significantly smaller than those in a four litre pot.
