Care at a glance

Light

Teddy Bear sunflower needs sun on the leaves, not just bright ambient room light. Requires a minimum of 6–8 hours of direct sun daily. Insufficient light causes weak, floppy stems and reduced flowering. Avoid shaded or north-facing positions. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water teddy bear sunflower weekly, or every 5–7 days during dry spells. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water deeply at soil level; allow the top inch of soil to dry between sessions. Young plants need consistent moisture to establish; mature plants are moderately drought-tolerant. Avoid waterlogging — root rot is the primary cause of failure.

Soil and pot

Teddy Bear sunflower grows best in well-drained, organically enriched loam. Prefers loose, humus-rich soil with a pH of 6.0–7.5. Incorporate compost before planting. Avoid heavy clay or waterlogged ground. Does not require highly fertile soil — excess nitrogen produces foliage at the expense of flowers. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Teddy Bear sunflower sits happiest at around 30–60% humidity and 18–30°C (64–86°F). Tolerates average ambient humidity. Good airflow around plants reduces risk of powdery mildew, which can be problematic in humid, still conditions. If you keep the room above 18–30°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed teddy bear sunflower sparingly. Apply a low-nitrogen, phosphorus-rich balanced fertiliser (e.g. 5-10-10) once when planting. Avoid high-nitrogen feeds; they encourage leaf growth over blooms. One mid-season feed is sufficient for most soils. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on teddy bear sunflower in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Powdery mildew — White powdery coating on leaves in warm, humid, still conditions. Improve airflow, avoid overhead watering, and apply a sulphur-based fungicide if severe.
  • Root rot — Caused by consistently wet soil or poor drainage. Yellowing lower leaves and wilting despite moist soil are key signs. Improve drainage and reduce watering frequency.
  • Aphid infestations — Clusters of small green or black insects on new growth and undersides of leaves. Knock off with a strong water spray or apply insecticidal soap; avoid broad-spectrum insecticides that harm pollinators.

Propagation

Sow seeds direct outdoors after the last frost when soil has warmed to at least 15°C (60°F), or start indoors 2–3 weeks earlier in peat pots (dislikes root disturbance). Sow 1–2 cm deep, thin to 30–45 cm apart. Germination in 7–14 days. Does not transplant well from open ground. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Teddy Bear sunflower is pet-safe. Helianthus annuus is listed as non-toxic to cats and dogs by the ASPCA. All parts of the plant — petals, leaves, and stems — are safe for pets. Large amounts may cause mild digestive upset. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Teddy Bear sunflower care — frequently asked questions

What is the common name for Helianthus annuus 'Teddy Bear'?

Helianthus annuus 'Teddy Bear' is most commonly called Teddy Bear sunflower, but it is also known as Teddy Bear sunflower, Dwarf Sungold sunflower. The names refer to the same species, so care instructions for Teddy Bear sunflower apply identically to anything sold as Dwarf Sungold sunflower.

How much light does teddy bear sunflower need?

Teddy Bear sunflower grows best in direct sun (at least 4-6 hours). Requires a minimum of 6–8 hours of direct sun daily. Insufficient light causes weak, floppy stems and reduced flowering. Avoid shaded or north-facing positions.

How often should I water teddy bear sunflower?

Water teddy bear sunflower weekly, or every 5–7 days during dry spells. Water deeply at soil level; allow the top inch of soil to dry between sessions. Young plants need consistent moisture to establish; mature plants are moderately drought-tolerant. Avoid waterlogging — root rot is the primary cause of failure. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is teddy bear sunflower toxic to cats and dogs?

Teddy Bear sunflower is pet-safe. Helianthus annuus is listed as non-toxic to cats and dogs by the ASPCA. All parts of the plant — petals, leaves, and stems — are safe for pets. Large amounts may cause mild digestive upset.

What USDA hardiness zone does teddy bear sunflower grow in?

Teddy Bear sunflower is rated for USDA zone 2–11 (grown as annual) and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
