Winters scenes around the garden. Photos taken by Royston Hunt. Frosty but apparently not quite a hoar frost. This is the definition of hoar frost: Hoar frost is a type of feathery frost that forms as a result of specific climatic conditions. The word ‘hoar’ comes from old English and refers to the old age appearance of the frost: the way the ice crystals form makes it look like white hair or a beard.
How does hoar frost form?
Ground frost forms when the air is still and cold, usually on clear winter nights. Water vapour in the air condenses on solid surfaces, and as the surface temperature drops below 0°C, ice crystals form.
Hoar frost requires slightly different conditions. It forms when the water vapour in the air comes into contact with solid surfaces that are already below freezing point. Ice crystals form immediately, and the ice continues to grow as more water vapour is frozen. On a still night, it can grow well on tree branches, where the surface temperature is unlikely to rise above zero for several hours.

Gay Lewis on the left in this photo organised the raffle. And Sara Villiers in next photos managed to ‘train’ lots of people in how to play duplicate bridge so they could participate.

With nearly 35 years in the green sector, its exciting to see how sustainability is now part of mainstream thinking – and I’ve played a part in that.
I’ve written or co-written nine environmental books, including The Green Consumer Guide (with John Elkington) which sold over 1m copies worldwide. In 1987 I co-founded environmental think tank, SustainAbility and since then have worked with a wide range of companies advising them on issues such as waste, recycling, packaging energy, climate change and deforestation.
In 1992 I went to Nairobi to celebrate my election to the Global 500 Roll of Honour for outstanding environmental achievement. That’s where I met fellow laureate Rene Haller, an inspiring man leading the way in eco-system thinking. A decade later, I co-founded the Haller Foundation, promoting sustainable living in Africa, taking Rene’s ideas into the wider community. In 2017, my interest in this continent led me to becoming a Trustee of CHASE Africa, which promotes family planning and women’s empowerment, particularly in rural areas.
In 2020, I became a non-executive director of the Big Yellow, self-storage, a FTSE 250 company and chair of their board-level Sustainability Committee. As a company with low energy consumption and a large amount of roof space, I identified a golden opportunity to significantly expand on their solar installations.
I’m also on the board of Rubbish Ideas, which was co-founded by my son, Connor Bryant and his business partner Jack Schneider. The key focus of the company, and its sister enterprise, The Rubbish Project is to provide circular economy solutions – using recycled materials, collecting waste, reducing carbon and making a positive impact on the planet.
I work from my home in Dorset and am lucky enough to have spent most of Covid 2020 starting a wilding project. Working with Operation Future Hope, we’ve been creating habitats for a wide variety of species from bees to barn owls – installing ponds, sowing wildflower meadows and nurturing our hedges and edges. Lots more wilding projects to come – keep up with some of them on my blogs…
