  • Griselinia Variegata leaves close upGriselinia Variegata plants
    Available in a 5 litre pot. A slower growing Griselinia, this attractive variety grows about 30cm / 1ft a year, if fed with a very good slow release fertiliser like Trevena Cross Fertiliser, making it very suitable for smaller sized hedges. It's attractive variegation is displayed on leaves that tend to be rounder in shape than on it's close relative Griselinia Green Jewel. Like the standard Griselinia, it will withstand salt laden winds but will only tolerate a seafront position if located in a sheltered estuary or inlet, like St Mawes or Falmouth in Cornwall. In exposed locations, Griselinia would need to be positioned several hundred feet away from the sea or for extremely exposed coastal sites like Land’s End, and Lizard Point in Cornwall, we would recommend an alternative like the tougher Elaeagnus or Olearia traversii. A per plant discount is available for bulk purchases of Griselinia Variegata hedging plants. This discount will be applied in your basket if applicable (begins at 10+ plants).

The fertiliser won't leach with heavy rainfall or be 'feeding' when the plant doesn't require it/out of growing season.  This 'slow release' fertiliser removes the need for regular feeding, and yet contains all of the essential nutrients necessary to produce a strong healthy plant.

    Cyathea australis - A large, evergreen fern with a rough, thick trunk. It grows up to 4 metres high pretty quickly with a spread of 6-8 metres and each frond can reach up to 4 metres long in good conditions! The Cyathea tolerates the sun as long as the soil is moist, but does need a good sheltered site to thrive. Some sources suggest it’s hardier than a Dicksonia Antarctica. It will be hardy to minus 8 degrees centigrade, but be aware that the fronds will get frosted in severe winters, so give the plant protection. Probably the best tree fern for a sunny site with its large evergreen fern and hairy trunk. Plant in a sheltered area or with light shade and add peat when planting or inside in a conservatory.
