Judging a wholesale seed catalogue by its crop group depth

A shop that stocks vegetables, herbs, flowers or microgreens needs to know whether a wholesale catalogue is deep enough in the groups it actually sells before it builds a selection. Depth is not one number: on the Bulk Seeds International catalogue it is expressed through the hierarchy of seed group, species and variety, and different crop groups sit at very different levels of that hierarchy. This guide shows how to read the catalogue's stated structure per crop group as a fit test for your own shelf profile, using only the counts and groupings the catalogue itself reports.

Depth has three levels in this catalogue

The catalogue describes itself as organised by seed group, species and variety. Each level answers a different question for a buyer. The seed group tells you whether your category is covered at all. The species count tells you how many botanical identities the group carries. The variety count under a species tells you how much choice a single plant type offers. Judging depth means checking all three, not just the top-level heading. A group with one species and one variety is thin for a shop that leans on that crop, while a species with dozens of varieties supports a focused range.

Compare the reported counts per group

The pages give concrete figures you can compare before opening any variety page. The microgreens group is indexed with nine species, including Amaranthus blitum with one variety, Beta vulgaris with sixteen, Brassica oleracea with forty-one, Brassica rapa with thirteen, Eruca sativa with five, Foeniculum vulgare with six, Rumex acetosa with three, Rumex sanguineus with three and Tropaeolum majus with one. The cabbage and kale group lists four species entries, among them Brassica greens with four varieties, kale with three, curly kale with two and green minaret broccoli with two. The tomato group lists two species: Solanum lycopersicum with forty-eight varieties and Solanum cheesmaniae with one. Read these as the shape of each group, not as stock guarantees.

Match the group shape to your shelf profile

A shop whose sales sit mostly in salad and leafy lines should look hardest at the groups with the widest variety spread, because that is where substitutable choice lives. A shop that sells microgreens as a niche add-on can work with a single variety under a species. A shop that runs a broad vegetable wall needs the group to carry several species, not one deep species. Write down your own shelf categories first, then place the catalogue's reported species and variety counts beside each one. Where a category maps to a species with only one variety, you are depending on a single reference rather than a range.

Watch for broad labels and mixed naming

The catalogue warns that some records use horticultural group names rather than a single accepted species name, and that the cabbage and kale group mixes cabbage, kale and broccoli under broad Brassica labels. A large variety count under a broad label does not guarantee interchangeable products: the catalogue states that a shared genus does not make names interchangeable. Preserve leaf-type and cultivar qualifiers, and where the botanical label is broad, treat the SKU as the identifier and ask for clarification. Depth judged on label breadth alone can overstate the real choice in a group.

Counts are catalogue entries, not lot statements

None of the figures establish anything about a particular seed lot. The catalogue explicitly says the heading describes catalogue organisation and does not establish that a seed lot is cleared for direct consumption, sprouting or another use, and that a listed weight-based price is not a seed-count conversion or a batch-specific germination statement. So use the counts to judge breadth of choice, then ask for the information relevant to the selected reference and destination. Depth of catalogue is one question; suitability of a lot is another, answered in the quotation.

Turn your depth verdict into a clean selection

Once you have decided that a group is deep enough, the enquiry itself is simple: choose the named variety rather than a broad category label, then give the SKU, quantity and unit for each selection. The catalogue notes that weight-based and seed-count prices are different bases of comparison, so keep the unit consistent when you compare figures. Available quantities, pack sizes and final prices are confirmed in the quotation, and an enquiry is non-binding rather than an order. A depth check done first saves you from discovering a thin group halfway through building a basket.

A short routine before building anything

List your shop's crop groups in the order they matter to your sales. For each, note the species entries the catalogue reports and the variety counts beneath them. Mark any group where your category rests on a single variety or a single broad label. Flag groups where naming is mixed and you will need SKU-level clarification. Keep the flagged items as questions for your enquiry rather than assumptions. This routine uses only the structure the catalogue publishes, so it can be repeated each season as your shelf profile shifts between, for example, vegetables and microgreens.
