Mail-Order Seed and Plant Catalogs: A Guide for Home Gardeners

Seed and plant mail-order is one of the oldest and most reliable catalog categories in the United States. Gardeners who skip the local garden center and order by catalog access a vastly larger variety of plants, heirlooms, and regionally adapted seeds than any physical store can stock.

American gardeners have been ordering seeds, bulbs, and bare-root plants through the mail since the 1800s. The seed catalog tradition predates the general merchandise catalog by decades — seed companies understood early that mail-order was the only practical way to distribute plant material to farmers and gardeners across a continent-sized country. That practical logic still holds today.

A well-stocked local garden center might carry 40 or 50 tomato varieties at peak season. A serious seed catalog carries 200 or more, including heirlooms, open-pollinated varieties, and regionally adapted cultivars that no mass-market retailer would stock. For gardeners with specific growing conditions, flavor preferences, or historical interests, mail-order is not a second choice — it is the only realistic source for what they need.

How seed catalogs differ from plant catalogs

The mail-order garden category divides into two distinct types of supplier, with different logistics and considerations for each.

Seed catalogs sell seeds — packets of dormant plant material that ships easily at any time of year, tolerates reasonable temperature variation, and has a long shelf life if stored correctly. Seed orders can often be placed in the fall for the following spring, and reputable seed companies hold orders for appropriate planting windows.

Plant catalogs sell live or semi-dormant plants: bare-root trees and shrubs, potted perennials, bulbs, tubers, and rhizomes. These are far more perishable than seeds. Bare-root plants ship in a narrow seasonal window when the plant is dormant, typically late winter to early spring. Potted plants and bulbs have their own windows. Ordering outside those windows means the company will hold your order until the appropriate shipping season, which can result in charges to your card months before the plants arrive.

Choosing a reputable seed or plant supplier

The seed and plant mail-order industry has a long history of strong operators and occasional bad actors. A few signals of a reputable supplier:

• Germination rate disclosure: Quality seed companies test their seeds annually and publish the germination rate for each variety. A germination rate of 85% or higher is standard for most vegetable and flower seeds. Companies that do not disclose germination rates are selling you unknown quality.
• Clear harvest year labeling: Seeds lose viability over time. Reputable suppliers label seed packets with the harvest or pack year so you know how fresh the seeds are. Avoid suppliers whose packets are undated or show older harvest years.
• Membership in seed preservation organizations: For heirloom and open-pollinated varieties, look for companies that participate in Seed Savers Exchange or similar networks. This signals a commitment to maintaining true variety characteristics.
• Plant hardiness zone information: For plants, a good catalog clearly states which USDA hardiness zones each plant is suited for and provides honest guidance about plants that are marginal in certain zones. Catalogs that simply say “grows everywhere” for cold-sensitive plants are not giving you accurate information.
• Realistic size and arrival condition descriptions: For bare-root trees and shrubs, a reputable company tells you what size plant to expect on arrival. “Bare root,” “one-year whip,” and “18–24 inches” are specific terms. Vague descriptions like “vigorous young tree” without measurements are a flag.

Timing seed orders correctly

Most experienced mail-order gardeners place seed orders in December or January, well before the spring planting season. The reasons are practical:

Popular varieties sell out. Heirloom tomato varieties from small seed companies can exhaust their entire season’s stock by February. If you wait until March to order for April planting, you will find many of the varieties you wanted are back-ordered or gone entirely. Early ordering guarantees variety selection.

Seed catalogs arrive in January and represent the company’s full offering for the year. Ordering from the new catalog rather than a carryover edition ensures you are looking at currently available stock and accurate pricing.

Winter ordering also gives you time to plan your garden layout before the seeds arrive, rather than trying to plan and plant simultaneously under spring time pressure.

Reading catalog plant descriptions effectively

Catalog plant descriptions pack a large amount of practical information into a small space. Knowing how to decode them saves time and prevents poor purchases.

• Days to maturity (for vegetables): This number tells you how many days from transplant (or from direct seeding, depending on the crop) to your first harvest under ideal conditions. Compare this against your frost-free growing season to determine whether the variety is realistic for your climate.
• Determinate vs. indeterminate (for tomatoes): Determinate varieties produce a concentrated harvest over a short window, then stop. Indeterminate varieties produce continuously until frost. For canning, determinate is often better; for fresh eating across the season, indeterminate is usually preferred.
• Disease resistance codes: Tomato and cucumber catalogs frequently list disease resistance abbreviations (V, F, N, T for tomatoes indicate resistance to verticillium wilt, fusarium wilt, nematodes, and tobacco mosaic virus). These matter significantly in regions with known soil disease pressure.
• Spacing requirements: Catalog descriptions typically list spacing recommendations that assume optimal conditions. In smaller gardens, many plants can be grown more closely with intensive planting methods, but the catalog’s recommended spacing is a useful starting point.

Handling live plant deliveries

When live plants arrive by mail, the unboxing and first care steps matter more than with any other mail-order category. Bare-root trees and shrubs should be unpacked immediately and either planted within 24 to 48 hours or stored with roots in moist material in a cool location. Leaving bare-root plants in a hot garage in their shipping box for several days is a common cause of failure that customers mistakenly attribute to the supplier.

Potted plants that have been in a dark shipping box for several days may show yellowing or stress. Most recover within a week or two once placed in appropriate light. Do not immediately move stressed plants into full direct sun — allow them a few days of indirect light to acclimate before transitioning to their intended location.

If plants arrive visibly dead, dried out to the point of brittleness, or clearly damaged by improper packing, contact the supplier promptly with photographs. Reputable mail-order plant companies stand behind their stock and will replace genuinely dead-on-arrival plants.
