Nasturtium Gleam Mixed

Nasturtium Gleam Mixed: variety and characteristics

Nasturtium Gleam Mixed (Tropaeolum majus) is an annual flower of the nasturtium family (Tropaeolaceae). Gleam Mix is a variety with a moderate spread and the one we would recommend for hanging baskets and for containers.

They offer a particularly pleasing choice of colours with all the shades you would expect – primrose, gold, orange, red and mahogany, plus a few surprises.

The flowers rise well above the foliage, some of them semi-double and double with upturned blooms. They flower just six weeks after sowing and will continue until autumn.

Nasturtium is a cheerful and fully edible flower: the flowers and leaves have a spicy, cress-like taste and decorate salads. The dwarf varieties are for borders and pots, the climbing ones cover fences.

When to sow Nasturtium Gleam Mixed

Nasturtium Gleam Mixed seeds are sown in February and March. The plants flower from July to October. The months are a guide for a temperate climate — in warmer areas sow 1–2 weeks earlier, in cooler or upland areas, later.

How to sow and grow Nasturtium Gleam Mixed

• Sowing method: direct
• Depth: 2 cm
• Spacing: 25–30 cm (dwarf), 40–50 cm (climbing)
• Germination: 7–14 days at 15–20 °C
• Position: sunny spot

It is recommended to sow the seeds directly outdoors in spring. Seedlings do not always transplant well into the garden when started indoors. Before sowing nasturtium seeds, soak the seeds overnight in warm water. The next day, plant the flower seed 1/2 cm deep in an area that receives at least 6 hours of direct sun every day. Work the soil so that it is fine and light. Flowers will appear 8 - 12 weeks after sowing.

Sow directly after the last frosts; soak the seeds for a few hours. Do not fertilise: in rich soil nasturtium produces leaves instead of flowers.

Flowering and uses

The flowers, leaves and green seeds are edible, for salads, sandwiches and "fake capers".
