Clavo Red Chilli Plug Plant

Sharp Heat, Serious Flavour.Heat Level: ★ ★ ★ ★ ☆


Clavo Red is an unusual Capsicum chinense producing large numbers of small, angular pods that ripen to a bright red. The name comes from the Spanish word clavo, meaning nail, a reference to the distinctive shape of the fruit.

Although generally described as a moderately hot chinense, with a heat rating of around 100,000 SHU, my experience suggests it can be considerably fiercer.

I grew Clavo Red for the first time this season and initially found it rather difficult. By midsummer the plant was still small, growth had almost stopped and the leaves had developed a mottled appearance. I was close to giving up on it when I decided to try a generous feed with a high-nitrogen fertiliser.

The response was remarkable. It took off like a rocket and eventually became one of the largest plants in my greenhouse. It certainly seems to be a fairly heavy feeder, although the pods were a little later to develop than on some of my other varieties.

By late season the plant was carrying an enormous number of small fruits with a rather unusual flavour. I had expected the heat to be relatively modest, but mine were surprisingly fierce.

Unlike the slow, building burn of many chinense varieties, Clavo Red delivers a fast, sharp heat, rather like being slapped on the tongue with an elastic band. There's a fruity flavour underneath, although less floral than a Habanero or Scotch Bonnet, with a slightly savoury character.

I've found Clavo Red particularly good for making relish. I cooked the pods with tomatoes, a little sugar and a dash of vinegar, and the combination worked remarkably well. The sweetness of the tomato balances the sharp chilli heat, making it particularly good with sausages, grilled meats and even cheese.

Anything, really, where you need something to cut through the richness. Considering how close I came to giving up on the plant, Clavo Red turned out to be one of the more pleasant surprises of the season.

Additional Information

▶ Species: Capsicum chinense

▶ Heat Level: Hot to very hot. Approximately 100,000 Scoville Heat Units (SHU), although individual plants may produce considerably hotter pods. The heat is fast, sharp and surprisingly explosive.

▶ Fruit Appearance: Small, angular, tapered pods that ripen from green to bright red. Produced in large numbers, particularly towards the end of the growing season.

▶ Flavour Profile: Fruity with a slightly savoury character, less floral than a Habanero or Scotch Bonnet. A distinctive flavour accompanied by an immediate, sharp heat.

▶ Vigorous Growth: Can develop into a large, highly productive plant. Mine was slow to establish but responded extremely well to a high-nitrogen feed, suggesting it appreciates generous feeding during active growth.

▶ Uses: Particularly good for relishes, chutneys and hot sauces. Combines beautifully with tomatoes, sugar and vinegar. Excellent alongside sausages, grilled meats and cheese, where its sharp heat cuts through richer flavours.

▶ Growing Conditions: Prefers a warm, sunny position and free-draining compost. Best grown in a greenhouse in the UK, with regular watering and feeding. Allow plenty of space for the plant to develop and expect the pods to mature relatively late in the season.

▶ 1. Easy to Grow: Some chillies are just a joy to grow — compact, reliable, and happy in a pot (5). Others shoot off in all directions or sulk at the first sign of wind (1). I’ve given higher scores to the ones that do well here in the UK.

▶ 2. Ornamental Quality: A few of these are real show-offs, with pods that look like jewels or dramatic foliage that turns heads. Others are more practical than pretty. This score is just about how good they look on the patio or in the greenhouse.

▶ 3. Heat Level: This isn’t a technical SHU score — it’s just a kitchen-friendly 1 to 5. A 1 means very mild (like a jalapeño), a 5 is properly hot (think Bhut Jolokia). It should help you judge what you’re in for!

▶ 4. Hardiness: How well do they cope with our unpredictable summers? I’ve given higher scores to the tough ones that keep going through cool nights, wind, or patchy weather without much fuss.

▶ 5. Culinary Use: This one’s about how often I actually use them. Some are perfect for pickling, stuffing or powders — others look good but don’t end up in many meals. If it’s flavourful and versatile, it scores high.
