Our seasonal plants are carefully selected to suit the current season's weather conditions, and each bloom bag arrives with its own product care booklet with clear instructions on how to look after your plants.
Please note: Your plants may look a little different from our photos, depending on what our growers have in stock. Whatever arrives, we'll make sure it's fresh and a close colour match

Common questions
How easy are the Bloom Bags to look after?
Our Bloom Bags are designed to be really easy to look after. They arrive ready-planted, so you simply drop them into your window box and water them as recommended in your care booklet. Regular dead-heading encourages new flowers. It's that simple: all of the blooms and none of the back ache!
What if my plants arrive damaged?
Please email us within 48 hours of delivery with your order number and clear, detailed photographs showing the condition of your plants on arrival. We’ll assess the damage and resolve the issue as quickly as possible, including arranging replacements where appropriate. Unfortunately, without photos taken at the time of delivery, we may be unable to confirm the issue as delivery-related or offer a replacement.
How wide are the Bloom Bags?
Our Bloom Bags are 20cm tall and 18cm wide, but they're easy to shape, so fit most window box sizes.
