One major family, capsicum annuum, includes popular varieties such as cayenne, serrano, jalapeño, and poblano, and is widely grown across different climates. Chilli peppers are used in a variety of cuisines around the world, including Mexican, Indian, and Thai.

Sweet and Mild Chillies: Exploring Sweet Pepper Varieties

Not all chillies are fiery – some are sweet and mild, perfect for adding flavour without overwhelming heat. Sweet pepper, for example, is known for its mild, sweet flavour and complete lack of spiciness, making it a versatile ingredient in many dishes. Bell peppers, a popular sweet pepper, have a Scoville rating of zero, meaning they are not spicy at all. Certain mild peppers, such as shishito or bell peppers, are prized for their slightly sweet and tangy taste, with a sweet flavour that makes them appealing for raw consumption and a wide range of culinary uses. These are ideal for salads, roasting, and stir-fries. When selecting types of green chilli peppers, look for varieties that are tender, mild, and easy to grow. For types of red chilli peppers, choose those that develop rich colour and flavour when fully ripe.

Mild chillies are perfect for beginners or gardeners who want versatile, low-heat options for the kitchen.

Medium Heat Chillies

If you enjoy a gentle kick, medium-heat chillies offer warmth and flavour without being overpowering. Both types of green chilli peppers and types of red chilli peppers in this category are versatile for cooking and preserving.

Medium-heat varieties are excellent for sauces, salsas, and roasting, and they tend to produce reliable harvests that you can enjoy fresh or dried. Jalapeño peppers typically range from 2,500 to 8,000 SHU, making them a popular choice for those who want moderate heat. Serrano peppers, with a heat level of 10,000 to 23,000 SHU, have a citrusy flavour and are commonly used in salsas. Your spice tolerance plays a key role in choosing which medium-heat chilli to use, as some may prefer milder options while others enjoy a bit more heat.

Hot and Fiery Chillies: Understanding Scoville Heat Units

For gardeners who love real heat, there are plenty of different types of chilli peppers that will get your taste buds tingling. Hot peppers are prized for providing intense heat and bold flavour to dishes around the world. Choose types of green chilli peppers for fiery fresh dishes, or types of red chilli peppers for long-lasting, intense flavour when fully ripe.

Many hot peppers are known for their intense heat, with extremely hot varieties reaching high Scoville Heat Unit (SHU) ratings. Some are considered one of the hottest in the world, such as the Carolina Reaper, currently recognised as the hottest pepper with a heat level of 1.4 to 2.2 million SHU, and the Bhut Jolokia (Ghost Pepper), which measures over 1 million SHU. The red habanero is another extremely hot pepper, ranging from 100,000 to 350,000 SHU, and is valued for its fruity, sweet flavour. Habanero peppers in general have a heat level of 100,000 to 350,000 SHU and are both fruity and sweet.

The Scotch Bonnet pepper, native to the Caribbean, is known for its fruity flavour despite its heat and is a staple in Caribbean cuisine. Bird’s eye chili, including the Thai Bird’s Eye chilli, delivers sharp, pungent heat (50,000 to 100,000 SHU) and is highly valued in Southeast Asian cuisine. African bird’s eye chilli is a distinct variety used in African and Portuguese dishes, especially in piri-piri recipes. In fact, smaller chilies like bird’s eye often pack more intense heat than larger varieties.

Thai chilli is essential in Thai cuisine, adding both heat and flavour to many traditional dishes. The Naga Morich pepper is notable for its slightly smoky flavour profile, with aromatic tropical fruit and floral notes that enhance hot sauces and marinades. Cayenne peppers, another popular hot pepper, range from 30,000 to 50,000 SHU and are commonly used for their moderate but noticeable heat.

Hot chillies are fantastic for making sauces, chutneys, and marinades, and they bring real character to your garden beds. The flavour profiles of chilies can range from smoky to tropical, offering a diverse palette for culinary creativity.

Tips for Growing Chilli Peppers

Whether you’re growing sweet, medium, or hot varieties, a few key tips will help you get the most from your chilli plants:

• Start seeds indoors – Chillies thrive in warmth; a propagator or sunny windowsill works best.
• Feed generously – Use liquid fertilisers once plants have true leaves to encourage strong growth.
• Support taller plants – Some chilli types benefit from stakes to keep them upright.
• Harvest regularly – Picking encourages more fruiting, and lets you enjoy chillies fresh, dried, or pickled. Fresh chilli peppers contain more moisture and are often hotter, while dried chilli or dried pepper has had its moisture removed for storage, which can make dried chillies milder than fresh ones, though this varies by variety.
• Mix varieties – Growing a combination of types of green chilli peppers and types of red chilli peppers adds colour, flavour, and variety to your garden. This also lets you add spice to your cooking in different ways, depending on the heat and flavour profile you want.

Exploring the different types of chilli peppers is a fantastic way to make your garden colourful and your meals exciting. From mild green chillies to fiery red heat bombs, there’s a type for every gardener and every kitchen. Focus on the varieties you grow, experiment with heat levels, and enjoy the unbeatable flavour of homegrown chillies.

Happy growing and may your garden be deliciously spicy!
