Thlaspi 'Green Bell'

Do you know that one element in a bouquet that brings everything together? That is Thlaspi 'Green Bell'.
This elegant filler grows straight up with countless small, green, bell-shaped leaves that look like little bells. They add air, movement, and fresh green structure to any bouquet or floral creation.

Why you want to sow this:

🛎️ Decorative seed stems – like green little bells in a row
🌿 Airy filler – perfect to make colorful flowers shine
✂️ Long-lasting in the vase – both fresh and dried
🌱 Easy to grow – just sow and admire

Sowing and care tips

• Sowing time: Sheltered in autumn or from late February – April (under glass) 

• Germination time: 7–14 days

• Sowing depth: Lightly press down, cover thinly

• Location: Full sun to light partial shade

• Height: 30-60 cm

• Details: Annual, but blooms abundantly and quickly. Perfect for early and midsummer bouquets.

Chrisje’s Tip:

Sow Thlaspi among your brightly colored flowers like cosmos, sweet pea, or rudbeckia. Those fresh green stems provide a calm point in your bouquet and complete the composition.
Leave a few standing until autumn – they dry beautifully on the plant!
