What can you tell us about your garden at the Show?

The garden is ultimately a love story and a want to be on the mainland when from an island the heart wants to be nearer and from afar that story is retold in a contemporary way via a gardens design. 

The main feature becomes one tree and a giant ray of sunshine bouncing off the waters reflection as you look from the opposite end whilst the ability to believe there is a way to get there makes matters of the heart and seeing that love entirely realistic, but only of a daydream. 

What are you most excited to see at the show this year?

The show gardens aside and in equal measures I have a real soft spot for the achievable gardens category. The imagination, creativity and industry collaboration that is required to piece together the drawings of the futures garden designers and their interpretations is deserved of huge ovation. For those lucky enough to get to see them, they are always worthwhile and I am entirely in awe of those who strive to realise in these categories. 

What is your favourite current industry trend?

I’ll take two on this if I may. 

Wildflowering meadows appearing by far more beautiful always than not real grass certainly seems to be leading one evolutionary transition whilst the step away from Buxus semprevirens has been a most welcome trend. The Royal Horticultural Society’s flagship garden RHS Wisley has been leading the latter charge for sometime and has “allowed“ others like the Saracocca humilis (one of the most beautiful scents I have ever met) to take a little of the centre stage. 

What sustainable practices have you seen highlighted in the industry at the moment?

There was an era of low to no (in some cases) maintenance requirements for some time requested by clients and that in our design office’s case statistically for the greater to have drastically changed, for the better, to a case where gardens now are more considerate of the world’s future. It doesn’t necessarily mean they have to look rugged but more there is an awareness through that design that it starts not just in our public spaces but also in our own back gardens. 

Fast Five

Favourite Flower/Plant

Gleditsia Triacanthos Sunburst – I have never ever seen one, even on the darkest of days, and not felt warmer in my heart. 

Pineapple on a pizza?

Pineapple on a pizza is internationally accepted as grounds for immediate divorce proceedings. In a nutshell, never ever. 

Gardening Gloves or Bare Hands

Bare hands. 

Favourite Season, 

Spring, just as the first buds appear on the Crataegus. Mesmerising always and the beginning of an entirely new chapter in life, again.

Foliage or Flora

The lead singers – those that flower, never ever look as good without the bridesmaids. A little of both in equal measures I think.
