Some like it hot - by Senior Lecturer Simon Hart

Simon Hart, Senior Lecturer in the School of Sustainable Environments, discusses the ornamental value of the Chilli pepper.

-----------------------------------------------------------------------------------------------------------------

Fresh chilli peppers (or chile if you prefer) are far more available than they have ever been as they are now being grown on a commercial scale in the UK.

Chilli peppers belong to the genus Capsicum, most falling into the species C. annuum, though some of the hotter types (eg. the scotch bonnets) are a different species,  C.chinensis.  Greenhouse trials carried out at Writtle College on behalf of Tozer seeds during summer 2013 featured over sixty different varieties, and this is by no means an exhaustive collection.

Growers have found that chillis do very well as a summer crop in greenhouses or polythene tunnels, they  give a reliable yield (the flowers are self pollinating) and providing  aphids are kept under control aren’t too troublesome in the way of maintenance.

Although famous for their variability in heat content, which goes from mildly warming to lethally hot, chill peppers also vary widely in size, shape and colour. As UK production becomes more widespread and availability increases more of the interesting colours and shapes are finding their way onto the market as fresh produce.

The ornamental value of fresh chilli peppers has been explored recently by BA Floristry students at Writtle College, who have been designing a range of chilli pepper based arrangements such as the example below.

The peppers themselves have been proving surprisingly versatile due to the wide variety of shapes, sizes and colours available.

Fruits are generally glossy, work well with similarly glossy foliage as background, but also bring an exciting variety of colour, shape and form to the design.

Below are a few of the different types the students have found work well in arrangements:

Scotch Bonnet type peppers are usually available in red, yellow and orange shades when ripe, though more unusually a deep glossy chocolate brown. Chefs use gloves when preparing these peppers as they are lethally hot, so take care when handling

Yellow fruited Cayenne type (right)

The red Cayenne peppers are fairly common, but the yellow fruited less so, this variety is small enough to grow as a pot plant and produces the peppers in clusters

Another Habanero type– the variety Hot Paper Lantern (left)

Hot like the scotch bonnets, but a more elongated fruit shape.  This variety looks quite dramatic if used as a length of stem with attached fruit.

Known for its high yield, the fruits are closer spaced along the stem than many other types. 

The unusual Cambuli (right) – highly decorative colour and shape, also note the particularly long stem on each fruit.
