2018 Seed list

The RHS Members’ Seed Scheme draws upon the Society’s diverse plant collections and wealth of expertise to offer members the exclusive opportunity to buy seed harvested from RHS gardens. Our seedlist is produced each year by a small, dedicated team of staff and volunteers, based at Wisley, who collect, clean and pack seed for members.

The RHS aims to enrich everyone’s life through plants so we hope you will be inspired to have a go at growing from seed, which can be fun and rewarding. Covering 200 species, our seedlist contains a range of plants including annuals, herbaceous perennials, trees and shrubs, some of which are rare and unusual.

2018 seed list


Applying for seed

Please ensure that you have your membership card to hand when you begin your order as you will be asked to enter your membership number.

This year we have increased the allocation of seed packets from 12 to 15 from our seedlist (please note only one packet of any one number can be supplied), including the 6 collections on offer. Each collection contains five packets of seed drawn from a possible seven packets, according to supply. As only limited quantities of some seed are available we strongly recommend that you also list up to five alternatives.  

Please note that we are only able to send seed to addresses in the UK and EU, Iceland, Norway and Switzerland.

Place your order

To take advantage of the Seed Scheme there is a charge of £8.50 and we hope you’ll agree that it’s very good value for money. This charge goes towards the cost of seed collection, administration and postage.

Orders can be made online anytime between 1 November 2017 and 31 March 2018. Alternatively, you can request a printed copy of our seedlist, which will be sent with an order form, by contacting our Membership Services Team:

Germination guide

Our Germination guide is available as a pdf; if you would like a printed version please send an email to seeddepts@rhs.org.uk with details of your name, address and membership number.
Information about sowing seeds is also available on the RHS website advice pages.

Ordering online - helpful hints

We recommend that you download the seedlist first, as this will enable you to choose your selections at leisure. Make a note of the number of your selections and use these when you order online.
Choose up to 15 items to enter as your ‘first choices’, then choose up to five items to put in your ‘alternative list’. The Seed Team will then be able to make substitutions if your first choice has run out. You may choose to order one or more of the collections but please remember that one collection has five packets of seed and will therefore use five of your choices.

When to expect your seed

The dispatch of orders will start in January 2018 and should be completed by the end of April. If you have not received your seed by 1 May please contact our Membership Services Team (contact details above).

Convention on Biological Diversity (Nagoya Protocol)

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.

  • 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 (pollinated naturally by either the wind or by insects without human intervention); 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 on the safe side, 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 endeavoured to exclude seeds of potentially invasive species.  For further information about these please see Schedule 9 of the Wildlife and Countryside Act (1981).

Find a Plant

The plants flagged with the cross symbol can be found in our Find a plant database, 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.


Plants for Pollinators

Those plants flagged with the bee symbol are ‘Plants for Pollinators’. This identifies those plants that are good for attracting pollinating insects into your garden. Plants for Pollinators is an RHS initiative, giving gardeners a comprehensive list of garden and wild flowers which are good for attracting bees and other insects into your garden.

Seed collecting leaflet

As well as offering our members the opportunity to purchase RHS seeds we also aim to inspire everyone to grow from seed by providing you with all you need to know about collecting, storing and successfully germinating your seeds. Our ‘Collecting seed from your garden’ leaflet tells you all you need to know about how to collect, clean and store seeds from your own garden. 

We do welcome any feedback you have about the seedlist and our email address is: seeddepts@rhs.org.uk
On behalf of the Seed Team we would like to wish you happy seed sowing in 2018!
