Mammoth Sunflower - GIANT - Seeds
Latin name: Helianthus annuus
How does a GIANT sunflower 🌻 in your garden sound to you?
Your kids (and you too) won't believe their eyes. Straight out of a fairy tale and legends, the Mammoth sunflower is gigantic. It grows at breakneck speed and can easily reach 2.5 meters!
Fascinating for the littlest helpers in the garden, who will love seeing the flower turn towards the sun.
Plant this if you want to wow your neighbours and the birds! It dries in the fall and becomes natures-own birdfeeder all winter long.
This variety, with huge flowers that can easily reach over 30 cm on plants 200 to 250 cm high, does not require staking.
What do you need to grow giant sunflowers like this? Seeds (obviously), compost, sun and water. See the Growing Instructions to grow the best sunflowers you can.
The seeds are also huge. You can harvest them in the fall to cook with or leave in place for your birdie friends.
