[[RESEARCH ENRICHMENT START]]
Zone 6B: Because the species included in the mix are unknown, do not assume outdoor winter hardiness in Zone 6B. Grow as container plants and protect from frost unless individual seedlings are later identified as cold-hardy species.
Germination: Unlike mature cacti, seedlings need high humidity and consistent moisture. Surface sow at 70-75°F and cover the tray with clear plastic or another humidity cover until seedlings establish.
Seed Saving: Seed-saving requirements differ by cactus species. Flowering may take several years and pollination requirements vary, so no single method applies to the unidentified mix.
Special Care: The packet contains unidentified cactus species, so mature height, spacing, flowering age, exact cold tolerance and species-specific care cannot be assigned reliably.
