We are trying to find out whether we can have ornamental plants and at the same time use them for their products or can we utilize small areas for multipurpose (for their beauty and their fresh products).
1. Ornamental pepper is one of them (see attached picture):
"Striking when in full fruit, ornamental pepper (Capsicum annuum) is a shrubby little plant with a tropical appeal. Most varieties that are bred for ornamental use hold their peppers in a upright position above the foliage. These are considered outstanding ornamental plants but somewhat expensive because usually they are sold in large pots. Peppers bred for eating also make attractive and colorful ornamental plants and are less expensive, but their peppers are usually borne lower on the plants, hanging in a downward position. Although ornamental peppers are edible, most people find them too hot to enjoy." [ http://homeguides.sfgate.com/care-ornamental-pepper-plant-43841.html ]
