Description
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. The leaves, flowers, and seeds of this nasturtium are edible, and the flowers bring a rich visual pop to salads and smart drinks. An AAS Winner in 1935.

| 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. |
| Growing |
Nasturtiums thrive in poor to average, slightly acidic, well-drained soil. Keep watered during dry weather, and do not fertilize. If aphids infest nasturtiums, cut off the infested growing tip and destroy it. Otherwise, a quick jet of water from the hose will dislodge and kill aphids. |
