Sweet Pepper 'Marconi Red' is an Italian type variety that has a mild sweet flavour with a medium thick flesh. The pepper is long & slender and measures about 6cm x 17cm long. It matures from green to red and is great in salads or for stuffing and roasting.
To ensure a good crop, it is best to sow with heat early and grow in a greenhouse/polytunnel. It can be grown outside but the crop needs quite a bit of warmth so crops may be smaller in size & quantity and not as many will ripen fully. 'Marconi Red' is one of the better varieties of sweet peppers for growing outdoors though.
It does do well in containers provided it is watered and has enough warmth and sun. They do sound fiddly but treat like a greenhouse tomato and you should be rewarded with lovely juicy peppers.
