5 nasturtium varieties I’m growing right now as a professional gardener – you can still sow these fast-growing flowers in June for late-summer color

Nasturtiums are, without doubt, one of the easiest annual plants to care for. I have grown them everywhere: from large terracotta pots alongside dahlias to vegetable patches in community gardens where they crawled and climbed 10 feet in every direction.

These are fuss-free plants. They don’t need much input, yet they more than deliver with masses of bright, edible flowers and tangled mounds of foliage. And, the best part? Nasturtiums are remarkably fast-growing. Even in June, you can still sow them and expect flowers by late summer, and in a mild fall, they’ll keep blooming into November.
