The Costa Rica Orange chilli plant thrives on strong contrasts. Under good sunlight, the foliage and unripe fruit can look very dark violet to almost black. As it ripens further, the fruit colour eventually shifts to a bright orange. As a result, the plant keeps looking different throughout the season.
How hot is Costa Rica Orange?
Published heat figures differ considerably. A range of roughly 30,000–150,000 Scoville Heat Units is often cited. We rate Costa Rica Orange at heat 6 out of 10 on our own scale. Since rare lines and growing conditions can cause differences, we think this transparent rating is more useful than a single, seemingly exact figure.
Why does the foliage get so dark?
The dark colouring is linked to anthocyanins and is encouraged by intense sunlight. This later creates a particularly strong contrast with the orange ripe fruit. We see this effect even more pronounced with Black Kathumby, whose foliage can turn almost black under plenty of sun with us.
A compact chilli for pot and patio
At around 50–80 cm, Costa Rica Orange stays comparatively compact. That makes it interesting for pot, balcony and patio. We recommend at least 8 litres, ideally 10 litres of soil volume; with 15–20 litres, the plant gets extra room. A sunny, warm and wind-sheltered spot supports both the colouring and the ripening.
