Our product developers and plant hunters scour nursery fields and glasshouses around the world in the hunt for the next big thing for your garden. If we can't find what we're looking for on our travels, we look to create the next big thing ourselves with our own breeding work.

Next season is set to be another great year for our new launches and we again have our hopes pinned on another win in the Chelsea Flower Show Plant of the Year 2020. Our previous winners include Hydrangea Runaway Bride and Foxglove 'Illumination Pink', both of which remain firm customer favourites.

But what will be your favourites of 2020. Here we reveal 10 of the best plant introductions launched in the Thompson & Morgan 2020 Spring Catalogue. All plants are now available for order, just follow the links below.

Opinions are split here on the nursery, making it hard for us to choose a stand out winner, but we'd love to hear your thoughts - Let us know which ones you'll be adding to the garden in 2020 via our Facebook page, Twitter or Instagram.

1. Six months of vibrant garden colour -
NEW Helichrysum 'Granvia Gold'

- Large and long-lasting flowers
- A unique and 'crispy' structure
- Strong garden performance

We've really struck gold with Granvia® Gold! It has remarkable big flowers in an intense bright yellow colour with a centre that turns orange with pollen as the flowers age. The unique structure of the papery, 'crispy' petals will grab your attention straight away. It's easy to grow, blooms early and is long-lasting. Here's a tip - the scented flowers can be harvested to use as perfectly dried flowers or fresh potpourri.

Sollya heterophylla is an attractive and abundant climber, flowering freely from June to October in a sheltered, warm and sunny position. But we've taken things further.
