Claim your free seed pack and help make a difference. Your mixed pack of seeds will contain rowan, dog rose, alder buckthorn and holly. Your pack will come with full planting instructions and care advice, and we’ll stay in touch to help you as your seedlings germinate and grow.The seeds we send you will be kept moist with compost to help them germinate. This means it will be harder to tell the different seeds apart when they arrive. If you would like to try and identify the seeds you're planting you can wash the compost off but then the seeds must be sowed immediately. It will be much easier to identify your seedling once it has germinated. Seeds will be with you by 10 March 2017.
