Judging Catalogue Depth in One Crop Group Before Ordering

A long catalogue page and a deep one are not the same thing. Before committing time to a selection, a reseller needs a way to read a single crop group and decide whether the range really covers a shelf or merely spreads a few entries across many headings. This guide shows how to use variety counts, sub-group structure and reference numbering as practical depth signals within one crop group, using the patterns visible in a trade catalogue as illustration.

Separate length from depth

Length is the total number of lines a catalogue shows; depth is how much choice exists inside the group you actually intend to stock. A long index can still be shallow per crop if every heading holds one entry. Pick the crop group that matters most for your shelf and count what sits inside it, rather than scanning totals. If your main group has thin coverage, the overall length of the catalogue tells you little about whether that shelf can be built from this supplier.

Count named varieties, not category labels

Within a group, look for named varieties under each species. A species heading with a single variety is a token presence; a species heading with a dozen or more varieties suggests genuine assortment. In the microgreens and sprouts catalogue, for example, the entries are grouped by botanical species with individual counts against each, such as Brassica oleracea with many varieties next to Tropaeolum majus with one. That spread is itself information: it shows where the depth is concentrated and where it is not.

Read the sub-group structure

A deep group usually has layers: a group heading, then species, then varieties, with indices linking them. The catalogue described here is organised by seed group, species and variety, and the microgreens group is broken into named botanical references under a broader heading. Ask whether the group you care about resolves into species at all, or whether it stops at a broad label. Headings that only say a category, without species beneath them, give you nothing to compare at reseller level.

Watch for mixed naming conventions

Depth signals weaken when a group mixes genus names, horticultural group names and cultivar names at the same level. A shared genus does not make selections interchangeable, and broad imported botanical labels may need clarification against the SKU. When a group uses consistent species-level headings and keeps cultivar qualifiers separate, you can read coverage more confidently. Where labels are inconsistent, note the open questions and plan to ask about them rather than assuming the numbering resolves them.

Use reference numbers as a structural clue

Reference numbering and the presence of SKUs at variety level show that each named selection is a distinct item you can request, not a descriptive note. Depth you can act on is depth backed by individual references. In your enquiry, identify the SKU, quantity and unit for each selection. If a group looks deep but you cannot attach a reference to several of its entries, treat those entries as unconfirmed until clarified.

Check how the group is indexed

Navigation reveals structure. A group that appears in the main catalogue index, has its own species A to Z route and lists related references is easier to assess than one reachable only through a general page. Use the A to Z species route to see whether the group's species appear there as named entries. A group that surfaces consistently across indices is more likely to be genuinely maintained than one mentioned in passing.

Set a depth threshold before you browse

Decide in advance what coverage your shelf needs: how many species, how many varieties per species, and whether you need several leaf types or one. Write the threshold down, then test the group against it. This keeps the judgement about whether the range supports your customers, rather than about how impressive the page looks. A group that clears your threshold is worth a selection; one that does not is better left for a later enquiry round.

Confirm depth with the supplier

Catalogue structure indicates potential depth, not confirmed availability. Available quantities, pack sizes and final prices are confirmed in the quotation, and a listed weight-based price is not a seed-count conversion or a batch-specific germination statement. After a structural read of the group, send your selection for confirmation. That way your depth judgement is tested against what can actually be supplied before you plan shelf space around it.
