Botanical info

Taxonomy
Kingdom: Plantae; Order: Asterales; Family: Asteraceae; Genus: Helianthus; Species: Helianthus annuus (common sunflower).
Distribution
Native to North America; now cultivated worldwide and naturalized across Europe, Asia, South America, Africa, and Australia.
Conservation
Not threatened (Least Concern); extensively cultivated. Choose sustainably grown, bee-friendly stems (minimal pesticides).
Presentation etiquette
Choose firm, upright heads with green centers just starting to open. Strip lower leaves, recut stems, and present in kraft/burlap with a water source. Use pollenless varieties for formal venues; avoid very somber funerals where bright tones may feel out of place.
Ideal delivery time
Morning delivery, especially in warm weather; 1–2 days before the event so blooms can open fully. Keep cool and hydrated upon arrival.
Toxicity
Generally non-toxic to humans and most pets. Large ingestions of leaves/stems may cause mild GI upset in cats/dogs; seed hulls can be a choking/obstruction risk. Use clean, pesticide-free stems.
Allergenicity
Low to moderate. Fresh sunflowers can shed pollen that triggers hay fever or contact dermatitis; pollenless/florist varieties reduce risk.

Meaning & taboos

Symbolism & color
Turning toward the light, steadfast loyalty, and cheerful vitality; a wish for warmth, abundance, and long life.

Growing & tools

Care & gear
Growing tips
Full sun (6–8+ hrs). Sow after last frost in well-drained soil (pH ~6–7.5). Space 12–24 in depending on variety; water deeply but infrequently. Feed lightly; overfertilizing causes weak stems. Stake tall types early. Deadhead branching kinds to extend bloom. Watch for aphids, snails, mildew, and birds; use netting if needed. 60–90 days to flower.
Recommended tools
  • Hand trowel and seed dibber
