Original Planting Method: Start indoors any time
Outdoor / Direct Sow / Transplant Window: Indoor/container; outdoors only after May 25 and before Sep 15
Germination Time: 14–30+ days
Days to Harvest / Bloom: Years to fruit from seed
Container Friendly: Yes, required
Pollinator Friendly: Flowers eventually, but unlikely quickly
Medicinal / Herbal Use: Edible fruit eventually
Perennial?: Tender perennial indoors
Succession / Reusable Notes: Not an outdoor annual food crop for Zone 6B.
Zone 6B Notes: Grow as a houseplant; overwinter indoors.
Companion Plants: Houseplants, cactus/succulent mixes
Avoid Planting Near / Watch Outs: Frost, wet soil

[[RESEARCH ENRICHMENT START]]
Zone 6B: Not winter-hardy outdoors in Zone 6B. Grow in a large movable container and overwinter indoors before freezing temperatures.
Germination: Seed-grown dragonfruit is genetically variable and may take years to fruit; purple fruit color cannot be guaranteed from an unspecified seed lot.
Harvest: Seed-grown plants may take several years to fruit. Harvest when fruit develops mature cultivar color and begins to soften slightly.
Seed Saving: Seedlings are genetically variable and generally will not reproduce a named clone true to type.
Special Care: Requires a strong trellis/support. Exact purple cultivar/species was not supplied, so cultivar-specific pollination compatibility, seed germination time and fruiting age are unknown.
