If you're sending cut flowers to a friend or clearing your attic of clutter, please consider using one of the organisations with whom Plant Heritage has formed affiliations:
When you purchase some flowers or a gift from the Charity Flowers website, 15% of the order price (not including postage or VAT) is given to the charity of your choice. When you select your product simply choose your favoured charity from the dropdown. With over 350 great causes represented not only will you be purchasing a wonderful gift, you will also be helping a charity.
Why not donate a portion of your auction price to Plant Heritage?
