News and events about White House Farm, Maurice Foster’s garden and arboretum in Kent, England









Welcome to the fourth White House Farm biennial newsletter, for Friends of White House Farm. This comes to you as an email twice yearly if you enter your email address here.
NEWS:
Maurice’s book ‘The Hydrangea: a Reappraisal’ was published in December 2023 by Crowood Press. It’s been well received: John Grimshaw said it was his book of the year; Francois Gordon that ‘if you buy only a single book on plants in 2024 you should make it this one’. But especially gratifying is the response of readers new to the genus, for example (a reviewer on Amazon): ‘It’s the best combination of a definitive guide on the genus as well as a great beginner book and a wonderful historical story of an iconic plant. Fantastic photographs and high quality narrative. A brilliant gift for any gardener or historian.’


To order a signed copy from us for £25 plus p&p, email us at whitehousefarmarb@mail.com. All proceeds from ordering through us benefit the White House Farm Arboretum Foundation.
In October 2023 Maurice gave a talk at Kew for staff and students, a revised version of his 2021 IDS Winter Lecture, ‘The Second Golden Age of Woody Plants’; and in November he gave a second talk on this theme for the IDS, selecting and discussing a further 80 or so remarkable plant introductions since c.1980. A version of this talk will be published as an article in the 2025 IDS Yearbook.
Julian Harber (a recognised authority on the genus Berberis) recently described a new species, Berberis ludingensis, based on a plant found by Maurice in Sichuan and grown under the name B. panlanensis Hort. at WHF for many years. The new species and its botanical description were published in Curtis’s Botanical Magazine in December 2023.


One of our Volunteers, Francois Gordon, will have his book about William Purdom translated into Chinese and published in Ghanzou province, China later this year. It’s a testament to the years of Francois’ detailed research about Purdom’s personal connection to China (Purdom learned the language, played a role in creating Chinese national forestry policy) that it could get such an accolade. We wish Francois and wife Elaine all the best as they travel to Lanzhou for the book launch.
UPCOMING EVENTS:
IDS Camellia Study Day
March 30th 9.30am-5pm
(IDS members £65 each, Junior IDS members £20. Click here for how to join the IDS).
Talks, tours and discussion of specimens with Maurice Foster, Jack Aldridge and Roderick White
A special opportunity to look in depth at Maurice Foster’s collection of Camellia at White House Farm. The garden is home to a representative assortment of over a hundred cultivars and hybrids, but what makes this collection of special interest is forty plus species cultivated in woodland conditions in chilly Kent, many of which have turned out to be hardier than expected, and excellent garden plants – not just for flower, but also for attractive foliage and form. There is much more to the genus than the seminal species and crosses (japonica, x williamsii, sasanqua, cuspidata, reticulata etc.)
Cut specimens of plants from the collection will be gathered for examination and discussion: participants are encouraged to bring any from their own gardens of special interest or for possible identification.



In addition to our own study days (see below) White House Farm is excited to be working with Garden Masterclass (Annie Guilefoyle and Noel Kingsbury). A series of collaborative events will enable us to share the garden, the plants and the knowledge built up by Maurice over a lifetime with new and wider audiences of garden designers, landscape architects and horticulture professionals/enthusiasts. This year we are offering a summer pruning workshop and three seasonal afternoon walks, led by Maurice and the other WHF Trustees, which will take in plant highlights and insightful details about their history, cultivation and use in a garden context.
April 4th Garden Masterclass – ‘Spring: a profusion of colour’

A reappraisal of the important ‘asperae’ subsection of the genus Hydrangea (aspera and involucrata) with an emphasis on the challenges of cultivating H. aspera and the gardenworthiness of recent new cultivars of H. involucrata.
