Yes, you can scatter lupin seeds. This is the easiest way to add these bright and bold blooms to your garden, but it’s important to note that it’s not always the most successful.
You may find that your seeds don’t have the chance to germinate due to the presence of slugs and other pests in your garden, and you may find the overall appearance of these flowers to be random and sporadic.
Steve says, ‘If you're scattering the seeds, you should do this in winter time and let them grow from then onwards. Sowing the seeds instead of scattering will offer you more certainty in how the plants are going to grow, as you can control this a bit more.’
If you are looking for that meadow look you can instead try a wildflower mat like this one from Crocus for £11.99, which includes Lupin Blue.
