Choosing the right chilli variety

Before you venture into chilli growing there are a few questions you should ask yourself:

• Do you want a spice-type or vegetable-type chilli?

Chillies can be divided into two types – spice and vegetable – depending on how they are used in the kitchen.

Vegetable-type chillies

Vegetable-type chillies are relatively large-fruited and thick-fleshed, and tend to be milder than the spice-type varieties. Because of their bulk, these chillies are used mostly as a vegetable, playing virtually the same culinary role as sweet peppers – they are ideal stuffed with meat, rice or cheese; chopped into salads or salsas; and cooked in stews, stir fries and omelettes.

Spice-type chillies:

The spice chillies – including the habaneros and superhots – are generally small-fruited and thin-fleshed, and are usually hotter than the vegetable chillies. They are used to add heat and flavour to a dish, but contribute very little bulk. In addition, they are ideal for drying and milling into a powder. Some varieties are also very attractive and can be used as 'edible ornamentals', and do well as houseplants.


• How hot do you want your chillies?

The heat level in chillies is measured in Scoville Heat Units (SHU). Generally we at Sea Spring Seeds categorise  heat levels according to the following formula:

  • Sweet: 0 SHU
  • Mild: up to 5,000 SHU
  • Low medium: 5,000 – 20,000 SHU
  • High medium: 20,000 – 35,000 SHU
  • Hot: 35,000 – 100,000 SHU
  • Very hot: 100,000 – 500,000 SHU
  • Superhot: 500,000 SHU +

Please note: the scale is highly subjective and depends on an individual's tolerance to heat.


• How large do you want your plant?

Some chilli varieties will grow into large plants, e.g., Mulato Isleno and Pimiento de Padron. These need to be grown in the ground or very large pots. Other varieties will always be small statured, e.g., Stumpy and Prairie Fire. These are good in small pots, and can be kept as edible house plants on a windowsill.

The varieties we sell vary considerably in size, and we give an indication of growth habit in each variety description.



• How experienced a grower are you?

There are five species of domesticated chillies (see 'Chilli factoids' for more information), and some of these species are easier to grow than others. Most of the chilli varieties we sell are Capsicum annuum or Capsicum chinense.

If you have never grown chillies before we recommend starting with a Capsicum annuum variety. They are generally quicker to germinate and faster to mature.

Capsicum chinense chillies tend to be slower to germinate, and the plants generally require more care than the C. annuums. Habanero is the generic name given to chillies belonging to this species, including the superhots. For more information on habaneros click here.
