For beds, borders, ground coverings, rock gardens, or other large-scale plantings, those are fantastic options. The 10′ tall climbing varieties may swiftly cover banks, trellises, and fences.

The Greek term tropaion, which means trophy, and the Latin word tropaeum, which Linnaeus called for its similarity to a classical trophy, are the sources of the genus name.

Tropaeolum majus: Characteristics

It’s 10 mm long, meaty, light green fruit is divided into three ribbed “seeds.”

Tropaeolum majus: Is it an indoor plant?

Due to their tenacity, toughness, and ability to adapt to adverse environments, nasturtiums will flourish in a range of circumstances. They thrive just as well in little rock gardens, hanging baskets, urban window boxes, courtyard gardens, and wide beds and borders. They even grow under trees, producing living carpets that effectively fend off weeds. Additionally, these plants are non-toxic, so you don’t need to worry if you have pets at home.

Tropaeolum majus: How to grow

Once all threat of frost has passed, sow seeds in the garden in late spring to early summer, or start indoors in peat pots four to six weeks before the typical last frost date.
Seeds should be sown 10–12″ apart, 1/2” deep (because they need darkness to germinate). To increase germination, soak the seed overnight. Depending on the temperature of the soil, they should emerge in a week to ten days.
Except in extremely poor soil, avoid fertilising because it will encourage leaf growth and suppress flowering.
Picking or deadheading the flowers will extend blooming. Till the first frost, the nasturtium will continue to blossom.
Water them throughout the entire growing season to keep them blooming even though they prefer dry soil and can withstand drought.

Tropaeolum majus: Care tips

Light requirements

Nasturtiums grow and bloom best in full sun, receiving six to eight hours of direct sunlight per day. Although it can survive in partial shade, this plant might not produce as many flowers. However, given that hot temperatures can induce leaf browning, some shade is really preferable in warm climates.

Soil requirements

Surprisingly, nasturtium flowers thrive in relatively infertile soil with adequate drainage. Overly rich soil produces a lot of greenery but few flowers. This plant grows best in soil with a neutral pH (6 to 8) and can tolerate dry conditions, though it prefers moderate moisture.

Water requirements

Nasturtiums prefer weekly watering, but can be watered more frequently if grown in a greenhouse or a sunny vegetable plot. Nasturtiums can withstand moderate droughts, but their blooms will likely fade, and their foliage will become spindly.
