Cap Mushroom (Red) Seeds

Some chillies earn their place on looks alone, and the Red Cap Mushroom is one of them. Named for its squat, wrinkled, mushroom-cap shape, it's a striking, ornamental pepper that dangles beautifully from the plant, and it packs a genuine punch to go with the good looks.

This one hails from Jamaica, and interestingly it's a Capsicum annuum, the same species as the humble bell, despite a shape and heat that suggest something more exotic. In fact, these old mushroom-type peppers are thought to be among the ancestors of the modern bell pepper, so there's a bit of history in the pot. The fruits grow up to 5cm long and wide, wrinkling as they ripen from green to a vivid red, with more than a passing resemblance to a Scotch Bonnet.

The flavour is fruity and intense, and the heat is real: firmly in hot territory, enough to earn respect but a long way short of the superhots. It's a proper cooking chilli that also happens to look fantastic growing.

This one suits the grower who wants both substance and style. It's productive, eye-catching, and hot enough to satisfy, without tipping into the extreme. If you like a chilli that pulls its weight in the kitchen and turns heads in the garden, the Red Cap Mushroom is a great pick.

As an annuum, the Red Cap Mushroom is fairly straightforward to grow, though it does want a decent warm season to ripen its wrinkled pods, so give it a good start in NZ.

Sow seeds indoors from late August to September. You can start in July with steady warmth, but there's less urgency than with the slow superhots, so spring sowing suits it well.

If you like, soak seeds for 12 to 24 hours before sowing to soften the coat, then pat them dry. Sow two seeds per cell, about 5mm deep, in good seed-raising mix. Keep them consistently warm at 20 to 30°C. Annuum seeds are generally obliging and usually germinate within a week or two.

Keep the mix moist but never soggy. Once seedlings are up with a couple of true leaves, pot them on and keep them warm and bright.

When they reach 100 to 150mm tall and the weather has warmed properly, move them to their final home, in the ground or a pot of 20 litres or so. Full sun and a bit of shelter, and they'll get on with it.

The plant grows to around a metre and crops nicely, so a stake is worth having once it's carrying a load of those chunky mushroom pods.

The Red Cap Mushroom makes a productive plant of around a metre, and it yields well, so a stake keeps it upright once the fruit sets.

Pinch out the main growing tip early to encourage branching. More branches means more of those distinctive mushroom pods and a bushier plant to carry them.

Water consistently, keeping the soil moist but never waterlogged. Pots dry fast in a NZ summer, so check them regularly, and steady watering also heads off blossom end rot on the pods.

Feed with a tomato fertiliser once flowering starts. Chillies and tomatoes want much the same things, so keep it simple.
It's a nicely productive variety, and those ornamental pods hanging from the plant are half the fun of growing it. Keep picking to keep the plant cropping through the season.

Like many chillies, it can be overwintered as a perennial. Bring it somewhere frost-free, cut it back in autumn, and it'll return in spring with a head start on anything grown from seed.

Expect your first ripe pods around 90 to 120 days from transplant. It takes a decent season to colour up those chunky pods, so patience helps, but the plant crops steadily once it gets going.

The pods start green and ripen to a vivid red, wrinkling into that characteristic mushroom-cap shape. Pick them fully coloured for the best flavour and heat, when they come away with a gentle tug. Snip rather than pull to protect the branches.

Given the heat, gloves are a sensible idea once you start cutting into them. At 30,000 to 50,000 SHU there's enough capsaicin here to leave a sting on the skin and to make eye-rubbing a genuine mistake, so glove up for prep and wash your hands well afterwards.

Keep picking regularly to keep the plant flowering and fruiting. Those wrinkled red pods look wonderful on the plant, but the more you harvest, the more it produces.

For storage, you've got options. The thinnish-walled pods dry reasonably well for flakes and powder, keeping for months in an airtight jar away from light. Fresh pods hold a week or so in the fridge, and they freeze fine too. With their fruity heat, they're excellent worked into sauces and preserves as well.

Make no mistake, this is a properly hot chilli, sitting at around 30,000 to 50,000 SHU. That's firmly in hot territory, roughly cayenne-level, and comfortably hotter than a jalapeño, several times over. It's the kind of heat that commands respect without tipping into superhot extremes.

What makes it worth cooking with is that the heat comes with fruity flavour rather than arriving bare, so it brings character to a dish as well as warmth. Closely related in style to the habanero and Scotch Bonnet in its fruitiness, though not in the same heat league, it's a genuinely useful cooking chilli.

As always, individual pods vary. Heat shifts with the season, the sun and how the plant was grown, and a long hot summer generally produces fiercer pods than a cool damp one. Some pods will run hotter than others, so treat each one with a little caution until you know it.

Handle it with sensible respect: gloves for prep, and keep the pods away from eyes, kids and pets. Used with a light hand, it adds a fruity, warming kick to all sorts of dishes without overwhelming them.

An easygoing plant with the usual watch-list.

Aphids will go for the soft new growth in spring. A blast from the hose or a squash between the fingers handles small numbers, and ladybirds and lacewings do the rest if you let them. Whitefly can build up in a warm greenhouse, so yellow sticky traps and decent airflow keep them honest.

At the seedling stage, damping off is the main risk. Use fresh seed-raising mix, avoid overwatering, and give trays a bit of air movement. Slugs and snails will happily mow down young transplants overnight, so protect new plantings until they've toughened up.

On the disease front, most trouble is water-related. Overwatering invites root rot, and erratic watering can bring on blossom end rot, those dark sunken patches on the pod tips. Consistent moisture and free-draining mix prevent most of it.

Nothing here is dramatic. A well-watered, well-drained plant in a sunny spot, with a stake to keep it upright, will crop happily all season.

The Red Cap Mushroom is a proper cooking chilli, and its fruity heat makes it a natural for bold, warming dishes.

Tex-Mex is its happy place. It's superb in chilli con carne, spooned through nachos, packed into tacos or fajitas, anywhere you want a fruity, cayenne-level kick. The heat is real, so use it with a measured hand, but the fruity depth it brings is exactly what lifts these dishes from ordinary to memorable.

Hot sauce is another strong option. That fruity heat makes a lively, characterful sauce, on its own or blended with tomato, fruit or other chillies. And because the pods have a Scotch Bonnet-like fruitiness, they bring warmth and flavour together in a way that plain heat can't.

Dried and ground, it makes a fruity, fiery flake or powder that's a great all-purpose seasoning for anyone who likes a bit of bite, ideal sprinkled over pizza, stirred into soups, or rubbed onto meat before grilling.

Because the pods run genuinely hot, this is a season-to-taste chilli rather than one to use by the handful. But used with judgement, it brings a fruity, warming intensity that makes it a genuinely useful pepper to have on hand, and a good-looking one to grow.
