2017/18 Seed List

Sorry, it's now too late to order seed from this distribution.
We have sent out all orders, and hope you enjoy growing the seed.

Hardiness Zones

We include both the new RHS Hardiness codes (provided for plants granted the RHS Award of Garden Merit and those in the RHS plant search) as well as the old USDA Zone ratings to obtain as full a picture of hardiness as possible for HPS members.
The new RHS Hardiness Ratings are explained in full on the RHS website at
The United States Department of Agriculture Zone Ratings are used to indicate the AVERAGE MINIMUM Centigrade temperatures which are generally tolerated by plants, shown by the table below. Most of the British Isles falls within Zone 8, with the western coastal fringes and some urban areas as Zone 9, and exposed mountainous areas as Zone 7.

 Zone 10 Zone 9 Zone 8 Zone 7 Zone 6 Zone 5
0 -5 -11 -16 -22 -26

The ‘Z’ codes are widely accepted, and useful as objective criteria for plant selection. However, they can be a blunt instrument for many British gardens, where periods of intense cold can alternate with relatively mild conditions over a typical British winter. Well drained soil, particularly over the winter months, is equally important in ensuring winter ‘hardiness’. In addition, shelter from frost or desiccating winds, whether from walls, plant companions or protective mulches, maximises the chances of winter survival. Other plants cannot tolerate hot dry conditions in summer, and need moisture or cool shade to flourish. Keep this in mind when considering hardiness.
Wherever possible, these specific requirements are provided in the brief plant descriptions. These can only provide general guidance given the wide range of individual HPS members’ garden conditions.

Potentially Harmful Plants

Plants marked are known to be potentially harmful, by internal ingestion, as an eye irritant or as a skin irritant. For detailed information, see:
