RHS SEED SCHEME FOR MEMBERS
The RHS has a small, dedicated team of staff and volunteers who collect,
clean and pack seed for members.
Applying for seed
As a member you can apply for up to 12 packets of seed selected from our seedlist, including
the nine collections on offer. Each collection contains five packets of seed which counts
towards your total of 12. As only limited quantities of some seed are available you can also
list up to five alternatives. The cost of the seed is £8.50, which helps us to cover our costs for
seed collection, admin and postage. Please note that only one packet of any one number can be supplied. This is an exclusive membership benefit and we hope you’ll agree that it’s very good value for
money, at 70 pence per packet (if 12 packets of seed are ordered).
If you are ordering online for the first time you will first need to register on the Members
page, which will give you a password that you need to use when ordering your seeds.
Orders should be made online at www.rhs.org.uk/seedlist, anytime between 1 November
and 31 March. Alternatively, you can request an order form and a printed copy of our
seedlist by contacting our Membership Services Team:

Convention on Biological Diversity
In accordance with the Convention on Biological Diversity (CBD), the Royal Horticultural
Society supplies seed from its garden collections on the conditions that:
• The plant material is used for the common good in areas of research, education,
conservation and the development of horticultural institutions or gardens.
• If the recipient seeks to commercialise the genetic material, its products or resources
derived from it, then written permission must be sought from the Royal Horticultural
Society. Such commercialisation will be subject to the conditions of a separate agreement.
3
• The genetic material, its products or resources derived from it are not passed on to a third
party for commercialisation without written permission from the Royal Horticultural Society.
•
It is a condition of supply that any publications resulting from the use of the plant
material should acknowledge the Royal Horticultural Society as supplier. A copy of
any publication, report or data gained from the material must be logged with the Royal
Horticultural Society Lindley Library. Open pollination
Our seed is collected from open-pollinated plants; therefore seed may not come true and may
be hybridised. As a result you may get some pleasant surprises! Please also note that some
seed is donated and is offered under the names provided by the donors.
Toxic Seeds
Whilst we make every effort to highlight those seeds which we know to be toxic it
should be assumed, to be safe, that ALL seed could be potentially harmful or cause skin
irritation. Therefore, as a precaution, and additionally to avoid any risk of choking, we
advise that all seed should be kept out of the reach of children and pets; and should
never be ingested.
Invasive Species
We have decided this year to exclude seeds of potentially invasive species. For further
information about these please go to the following website:
www.fera.defra.gov.uk/plants/documents/schedule9Dec10.pdf
Find a Plant
The plants flagged with the cross symbol can be found in the Plants, Find a plant section of
the RHS website, where you can find much more information such as growing information,
advice and photos. Find a plant is constantly being updated so more plants may be added
during the year. www.rhs.org.uk/plants
Perfect for Pollinators
Those plants flagged with the bee symbol are ‘Perfect for Pollinators’. This identifies those
plants that are good for attracting pollinating insects into your garden. Perfect for
Pollinators is an RHS initiative. A comprehensive list of garden and wild flowers which
are good for attracting bees and other insects into your garden is available on the
RHS website: www.rhs.org.uk/science/conservation-biodiversity/wildlife/encourage-wildlifeto-your-garden/plants-for-pollinators
