This semi-trailing Nasturtium wanders 1m (36") and more. Large, fragrant, double and semi-double flowers come in a beautiful range of colours. Encourage it to climb by tying. Sow Glorious Gleam nasturtium seeds to fill in a large area quickly. Glorious Gleam Nasturtium seeds can be direct sown in the late spring or early summer. Try them in hanging baskets or along a rock wall. All Nasturtiums tend to self sow, but they are tender plants and easy to control.

Timing
Sow indoors in peat or coir pots 2-4 weeks before the last frost date. Better yet, direct sow from 1 week after last frost and repeat at 2 week intervals into early summer. Optimal soil temperature for germination: 12-18°C (55-65°F). Seeds will sprout in 7-12 days, perhaps longer outdoors.

Starting
Sow seeds 5mm – 1cm (¼”-½”) deep. If starting indoors, provide darkness during germination, followed by bright light. Space smaller varieties 15-30cm (6-12″) apart, and the big ones like Tall Single 60-90cm (24-36″) apart.

Companion Planting
Nasturtiums make a good trap crop for aphids, and they deter whiteflies, cucumber beetles, and attract predatory insects. It is a good companion for Brassicas, cucumbers, melons, radishes, and tomatoes.
