Terms of Trade and General Information
Our customers are world-wide and live in all climates, so we cannot always advise on the suitability of particular species.
The sub-lists and USDA climate zone a species is allocated to will be a guide, unless you have knowledge of the plant in question we strongly advise checking horticultural references for the species and for your temperature range and conditions.
Some of our USDA climate zone ratings were added many years ago, more recent experience has shown that some plants are much hardier than previously recorded. We have updated ratings for some bulbous plants and herbaceous perennials.

    Phytosanitary Certificates

    If a phytosanitary certificate is required, please click here.
    Phytosanitary Certificates specify that the listed seeds are free from certain diseases. That, if necessary, they have been treated chemically or physically against specific diseases or pests (only applies to a narrow range of seeds, from and to certain countries). And that there is not any contamination (weed seeds, fungus, dirt, anything that might harbour pests or diseases).
    If you do not know whether your seeds need certification, please check with your Ministry of Agriculture.


    Seed Viability

    To provide seed in the best possible condition, we arrange for collection in the country of origin at peak maturity, the date of which will vary from year to year. Seed is airmailed to us, and reaches you with the best germination potential - especially important with short-viability exotic seeds. Thus we need to take advance orders, and seeds will be forwarded to you as soon as we receive them. Thousands of seeds, mainly with longer viability, are available from stock.

    Conditions of Sale

    available for preorder
    These seeds are not in stock at our sales office, and we need to ask for them to be sent by our collectors or growers, most seeds are waiting to be shipped to us as soon as our request is confirmed.
    Non stock seeds may be seasonal, short viability, of limited demand or rare.
    Seasonal: some seeds are only available in season, these often need to be ordered in advance, to reserve seeds of limited availability, to have seeds collected that may otherwise not be collected, or to reserve seeds that would otherwise have other uses.
    On species' information pages there is a seasonal availability link, the seasonal availability page gives dates when we have shipped seeds in the past.
    Short Viability: usually also seasonal, short viability seeds have to be dispatched while they are fresh.
    Limited Demand: a majority of the seeds we offer have never been ordered, we usually do not stock seeds unless they can be stored, and are frequently ordered.
    Rare: often seasonal, rare seeds need to be reserved and are usually sold on a first come first served basis.

    Should your order for non-stock items be placed after the seed season, supplies may have sold out, and there could be a delay. We shall then carry out your order, unless otherwise instructed. In the event of further unavailability due to crop failure or other unavoidable cause we will advise so that you may re-order or have any advance payment refunded.

    B & T World Seeds' Stock List

    Information in our lists is provided for general guidance only, and we believe that the seeds are correctly named and free from disease etc. We depend upon knowledgeable collectors in source countries, but seeds, being mainly from natural sources, variation due to 'open pollination' is possible. Following custom in the trade, we give no warranty, express or implied, as to the viability or description of the seed, nor can we be responsible for the resulting plant crop or its possible misuse. Should you have any complaints please let us know.
