Garden timing

Start indoors 5 to 8 weeks before last frost; warmth matters.

Transplant once nights are reliably warm.

Plant intelligence

Use one square once heat is reliable; it behaves better than many summer flowers in tight grids.

Species and variety notes

Classic globe types stay tidy; taller fireworks types need more height planning.

QISseries
84small-bed fit

A dependable cutting series for small-space stems.

Best use: cut and garden display. Tradeoff: wait for real warmth before judging performance.

Fireworkscultivar
68small-bed fit

Beautiful and bee-friendly, but not as compact as standard globe types.

Best use: cut and garden display. Tradeoff: needs edge placement or support so it does not shade smaller crops.

Companions

pepper, basil, zinnia, celosia

Cautions

Slow until real heat arrives.

Do not overwater young plants.

Perenual API88/100optional key: Flower and ornamental drill-down, plant photos, care flags, toxicity, bloom data. Limit: Requires an API key and plan-aware caching, so it should enrich records without blocking the app.
Trefle API84/100optional key: Scientific names, subspecies, varieties, hybrids, synonyms, and broader botanical cleanup. Limit: Requires a token and should be treated as a reviewed import layer, not a live page dependency.
USDA PLANTS downloads82/100download cache: Standard names, plant symbols, distribution, native status, and conservation flags. Limit: Best consumed as periodic downloaded data instead of one-off runtime requests.
