Vase, garden, season & vase life
Summer in a flower: where sunflowers come from, when they are in season, and what you need to do so they don’t droop after just three days. Recommended in this context: Golden Hours. Recommended in this context: Sun-Yellow Dreams.
There’s hardly any flower that lifts the mood as instantly as a sunflower. You can place one in the dreariest room and it immediately feels brighter. We notice it in our shop every year: as soon as the first delivery arrives in July, people reach for them with real excitement.
Here you’ll get the practical version: how sunflower care in a vase really works, when the best sunflower season is, and how to grow them in your own garden.

Where does the sunflower come from?
The sunflower is a child of the New World. Indigenous peoples in North America were cultivating it as a food crop around 4,500 years ago. The Aztecs revered it as an image of the sun god.
Spanish sailors brought it to Europe in the 16th century. It made its breakthrough as a useful crop in 19th-century Russia — that’s where sunflower oil was discovered.
A fascinating detail: young sunflowers show heliotropism — they turn their heads with the sun from east to west. Mature plants remain facing east. Learn more in the article Orchid guide for healthy blooms.
Meaning of sunflowers
The meaning of sunflowers is, above all, pure joy for life. Giving someone sunflowers says: “You are my sunshine.”
- Yellow: Joy, energy, summer, optimism
- Orange/Red: Warmth, passion, an autumn feel
- Brown/Cream: Naturalness, groundedness
A bouquet of sunflowers suits almost any occasion — a birthday, housewarming, get-well wish, or simply a thoughtful little gift.
Sunflowers in a vase — the right care
Cutting sunflowers
Cut the stems at an angle with a sharp knife. The stems are thick and fibrous, and the angled cut significantly increases the surface area for water uptake. Remove all leaves below the waterline.
Plenty of fresh water
Sunflowers are real heavy drinkers. Use a large, sturdy vase and plenty of water. Check daily — on warm days, a single sunflower can drink an impressive amount. Change the water completely every 2 days.
How to make sunflowers last longer
Despite their name, as cut flowers they need no direct sun. Bright and cool is ideal. 18–20°C, and not next to a radiator. Use flower food, or add a teaspoon of sugar and a splash of vinegar to the water.
Pollen tip: Sunflowers tend to shed pollen onto tablecloths. If you want to avoid that, carefully remove the anthers in the center of the flower with tweezers before they open.
How long do sunflowers last?
With proper care, 7–10 days. In a hot kitchen at 25°C, more like 5 days; in a cooler room at 18°C, a good 10 days. Recut the stems every 2–3 days.

Planting sunflowers — garden & balcony
Sowing
Sow seeds directly outdoors from mid-April, 2–3 cm deep, with 30–50 cm spacing. You can also start them indoors on a windowsill from March. Seedlings appear after 7–14 days.
Location & Care
Full sun — at least 6–8 hours. Nutrient-rich, well-draining soil. Water regularly and avoid waterlogging. Apply liquid fertilizer every 2–3 weeks. Support tall varieties with a stake.

Frequently asked questions about sunflowers
7–10 days with proper care. Cut the stems at an angle, use plenty of cold water, add flower food, and keep them cool and bright — but not in direct sun.
Absolutely! Dwarf varieties like 'Teddy Bear' or 'Pacino' only grow 30–60 cm tall and fit perfectly in large balcony planters. Full sun, water regularly, fertilize every 2 weeks.
Yes! Let the head dry, remove the seeds, and roast them at 150°C. This is really only worthwhile for large-flowered varieties — dwarf varieties hardly produce any usable seeds.
