Botanical info

Taxonomy
Life cycle: annual (therophyte). Ornamental annuals span multiple families, notably Asteraceae (marigold, zinnia), Solanaceae (petunia), Amaranthaceae (celosia), and Plantaginaceae (snapdragon).
Distribution
Cultivated worldwide across temperate and tropical regions; used as seasonal bedding in USDA Zones 2–11; native ranges are species‑specific.
Conservation
As a group they are not of conservation concern, but favor open‑pollinated, non‑invasive cultivars, save seed where possible, use peat‑free media, and grow pesticide‑free to support pollinators and local biodiversity.
Presentation etiquette
Present as a seasonal bouquet or potted/bedding pack with a simple care tag. Use breathable, recyclable wrap, avoid strong fragrances for hospitals, and select colors appropriate to the recipient and occasion.
Ideal delivery time
Early morning or late afternoon in cool temperatures; deliver bedding plants near the local last‑frost date for immediate planting, and cut flowers at soft‑bud stage for longer vase life.
Toxicity
Varies by species; many are non‑toxic, but some annuals can be harmful if ingested (e.g., sweet pea seeds; castor bean highly toxic). Verify species‑specific toxicity and keep away from pets and children.
Allergenicity
Generally low to moderate and species-dependent; choose insect‑pollinated, low‑pollen annuals (e.g., begonia, impatiens, snapdragon) for allergy‑sensitive recipients and avoid heavy‑pollen types like some sunflowers and daisies.

Meaning & taboos

Symbolism & color
Annuals represent the vivid intensity of a single season—cheer, renewal, and living in the moment—celebrating present beauty and fresh starts.

Growing & tools

Care & gear
Growing tips
Sow after last frost when soil is 15–21°C; provide 6–8 hours of sun and well‑drained, compost‑amended soil. Space per variety, water deeply 1–2×/week, mulch to conserve moisture, deadhead to prolong bloom, and feed lightly every 3–4 weeks. Protect from frost and harden off transplants.
