About Tropaeolum majus 'Jewel of Africa'

Tropaeolum majus 'Jewel of Africa' · also called Jewel of Africa Nasturtium, Variegated Nasturtium · flowering

'Jewel of Africa' is a climbing, variegated nasturtium with cream-marbled foliage and a mix of yellow, red, cream and peach trumpet flowers. Vigorous and easy, this fast-growing annual scrambles up supports or trails from containers. Both flowers and peppery leaves are edible. It thrives on neglect and poor soil, flowering best when not over-fed or overwatered.

Mature size: 1.5-2 m climbing or trailing length; foliage mounds 30-40 cm tall when unsupported.

Indoor size vs how big it gets in the wild

Tropaeolum majus 'Jewel of Africa' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 1.5-2 m climbing or trailing length. In the ground with no restriction it is a completely different plant — foliage mounds 30-40 cm tall when unsupported. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Tropaeolum majus 'Jewel of Africa' is a fast grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: do not feed routinely. nasturtiums flower best in lean soil; excess fertiliser, especially nitrogen, produces abundant foliage and few flowers. at most, an occasional very dilute high-potash feed in containers.

Want this turned into the right next pot at the right moment? The pot size calculator and the tropaeolum majus 'jewel of africa' repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast tropaeolum majus 'jewel of africa' grows.

How to keep tropaeolum majus 'jewel of africa' smaller

You are not stuck with the maximum size. For tropaeolum majus 'jewel of africa' specifically, these are the levers, in order of impact:

Choose a compact or dwarf variety of tropaeolum majus 'jewel of africa' from the start — that is the most reliable size control for an annual.
Grow it in a smaller container to naturally limit how large it gets.
For some crops, pinching or pruning the growing tips keeps the plant shorter and bushier.
Sow a little later or space plants closer if you specifically want smaller individual plants.

How to grow tropaeolum majus 'jewel of africa' bigger or faster

Feed appropriately for the crop and never let it check (stall) from drought or cold.

Light is almost always the ceiling. The tropaeolum majus 'jewel of africa' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.
