Reading the species A to Z as a range map

A reseller planning a seed range needs a quick way to judge what the catalogue actually covers before committing time to individual variety pages. The species A to Z index serves this purpose: it lists botanical names and the number of varieties recorded against each one, so the breadth of a crop group becomes visible in a single view. This guide treats that index as a coverage map, showing how to compare it against the range you intend to stock and how to decide which crop groups to pursue and which to leave out. It is for seed shops, garden retailers and resellers, not for end customers.

What the index shows and what it does not

The A to Z index is a name-level overview. It lists botanical species names alphabetically, shows the number of varieties recorded for each species, and indicates how many entries a seed group holds. Flower seeds, for example, are recorded as 580 species, split into annuals, biennials, perennials and a houseplant group with no species at present. What the index does not show is whether a species is suitable for your market, what a variety costs, or whether import conditions allow it. Treat the index as a first filter, not as a stock decision.

Reading species counts as range breadth

Compare the number of varieties per species rather than the number of species alone. A species with many recorded varieties offers choices within one botanical name, which suits a shop that wants depth in a familiar crop. A species with a single variety offers a narrow entry point, useful when testing interest without committing to a wide selection. Both are legitimate, but they answer different retail questions, so read the counts alongside your intended shelf space.

Comparing the map against your intended range

Write down the crop groups your shop intends to carry, then check each group against the index. Where a group appears broadly, the index confirms the catalogue can support that part of your plan. Where your plan calls for a botanical group the index does not list, that is a signal to ask about an unlisted variety rather than to assume the range must change. Doing this before opening any variety page keeps the comparison at the level of coverage rather than detail.

Using group totals to size a first selection

Group totals help you decide how much of a group is realistic to review. A group with hundreds of species cannot be reviewed species by species in a first pass, so pick a small set of botanical names to examine and leave the rest for a later stage. Smaller groups can be reviewed more completely. The index gives you the counts needed to make that judgement without clicking through every entry.

Deciding what to leave out

A range plan is as much about exclusion as inclusion. If the index shows that a crop group is thin in the species relevant to your shop, or that your plan depends on groups the index does not cover at that level, record the decision to leave it out now. A written decision prevents the same question from being reopened on every catalogue visit and keeps the enquiry focused on groups you can realistically stock.

Where the index sits before variety pages

The index is a layer above variety pages, and the catalogue is organised by seed group, species and variety. Use that order deliberately: group totals first, species names second, variety detail last. Reversing it, by browsing variety pages first, tends to produce a selection shaped by whatever you happened to open rather than by your range plan. The index is the cheapest place to change your mind.

Recording coverage decisions for the enquiry

Note for each group whether it was included, reduced or excluded, and why. These notes become the basis for the enquiry basket and for later comparison with the quotation. A catalogue listing is not confirmation of import eligibility, so any species you decide to pursue still needs its destination conditions checked before a shipment is arranged. Keep coverage decisions separate from supply questions so each is resolved at the right stage.
