Six frost-proof plants that sell out every spring and where to buy them

The sun has finally broken through the clouds above the UK, bringing with it plenty of cheer as spring approaches and warming the faces of gardeners as they prepare their lots for the outdoors months ahead.

Now that most of the snap-frosts are behind us for the winter, it is the perfect time to get some perennials dug in. These hardy plants can survive what is left of the cold and add immediate colour to your garden. If you are hoping for a bright, vibrant, fragrant, easy-to-care-for, pollinator-attracting garden from this month, then it's well worth investing in some quality outdoor plants.

And there's no better place to do so than on Yimbly.com. The online market place has a whole host of pretty perennials that you can order now. Whether you're a gardening novice getting their fingers soily for the first time, or an expert looking to add something rare and unusual to your flower bed, there is something on Yimbly.com for you.

This collection comprises double ellen red, pink and picotee Hellebore, a hardy perennial that blooms in the winter. The flowers bring a magical touch to your garden during the colder months, while most other plants are dormant. Every winter, large, double, cup-shaped flowers are produced with a delicate appearance that belies their ability to survive a blanket of snow. These blooms are an excellent addition to any garden as they provide a food source for the earliest emerging pollinating insects.

Flowering period: January to May.

This is a plant that stands out thanks to its unique green-tinted blooms, which start as pale lime and gradually deepen into a vibrant, emerald shade as they mature. It is a fantastic choice for modern gardens or mixed borders.
