Growing Flower Seeds

Growing your own flowers from seed is not only great value but can be very rewarding too.

Unwins offer a wide range of flower seeds to choose from and not just annual bedding, so do try growing perennials from seed too. It is so easy to do!

Each Unwins seed packet has detailed instructions on sowing depth and the right temperature for germination. Sow large seeds individually. If seed is fine use a tiny pinch for each pot. If you need a lot of plants sow into 24 or 48 cells.
