What Nasturtium Scarlet Gleam is

Nasturtium Scarlet Gleam (Tropaeolum majus) is an annual flower of the nasturtium family (Tropaeolaceae). Nothing is nicer than these popular annuals growing in the flower garden!

They are easy to establish from seed and are reliable for a great display every summer through to autumn.

The flowers of Scarlet Gleam are about 1 - 2 cm across and a brilliant shade of scarlet.

All parts of the plant have a peppery taste, similar to rocket or watercress.

In ancient times this large flower seed was even used as pepper.

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 Scarlet Gleam

Nasturtium Scarlet Gleam 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 Scarlet Gleam

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".
