Planting Day 2025

It’s Planting Day for 178 schools across the UK today!
More than 18,000 bulbs will be planted by over 7,000 primary school scientists as part of this exciting outdoor investigation exploring how a changing climate affects the flowering dates of spring bulbs.

Follow the project and the experiences of our Super Scientists through this blog or on X at @ProfessorPlant.

Project team members are visiting several schools today to celebrate the 20th anniversary of Planting Day, and we look forward to receiving updates and photos from schools across the country.

Competitions and Creative Projects

Schools are invited to share their photos and creative media for our Planting Day Photo Competition. We’ll showcase the winning entries here next month!

We’re also running the Bulbcast Competition, where participating schools create short videos highlighting their favourite parts of the investigation. Resources to support this can be found here.

And for this special anniversary year, we’re thrilled to launch a Name the Daffodil Competition! Participants can suggest names for a brand-new daffodil variety commissioned to mark the 20th year of the investigation. You can see what our daffodil looks like in the attached image and find inspiration and guidance in the resource linked here. We can’t wait to see your entries!

A Special Display at St Fagans

The fantastic Gardening Team at St Fagans National Museum of History have been joining in the celebrations too! They’ve planted a commemorative display and created a beautiful woven planter for the project, which you can see in the attached images.

Get Involved

Feeling inspired? Why not plant some bulbs this October and share your images with us!
We’ll also be hosting free planting activities for families at St Fagans National Museum of History and National Museum Cardiff, where visitors can learn about plants and adopt their own baby bulbs. Find out more about how to join these sessions on our website.

Once schools have adopted and planted their bulbs, they will set up outdoor weather stations. From 3 November, they’ll collect daily weather readings every day that they are in school and upload these weekly to the Amgueddfa Cymru website. You can follow their progress here.

We’re so excited to get this year’s project underway and to share the journey with you all.

Here’s to another year of discovery, teamwork, and blooming science!
