Carol celebrates some of the season's most beautiful - and tiny - flowering treasures, looking at how to choose them, how to plant them and how to care for them. She also visits one of her favourite spring wildflowers in a local wood - the humble celandine - to see how it grows in its natural habitat.

At Glebe Cottage in Devon, the most regal of all the summer bulbs are the regalia lilies, and now is the time to plant them. Many buy them as expensive cut flowers, but Carol reveals how to grow them from bulbs. She also explains the best ways to sow beetroot and brassicas.
