My new favorite sweet pepper to grow at home is the hybrid Italian variety, 'Giant Marconi' (Capsicum annuum 'Giant Marconi'). It's one of the largest of the Italian sweet peppers and has an oblong profile with a slightly lobed stem end. The fruits reach 6-8 inches or more in length.

This has become my new favorite sweet pepper. It grows well here and produces very large peppers with a mild, succulent flavor. I have had no problems with this plant. It loves the heat, tolerates dry spells, and goes from a lovely dark green to a brilliant red as it ripens.

Our favorite pepper for grilling. I have grown these for a few years now and they have a good track record. I do have to stake the plants because the peppers are so large and produce so well that they pull the plant over by the end of the season.

These are very prolific peppers! I have to stake these, as the plants have so many fruits, they get weighed down, and the fruits are in danger of sitting on the soil. Great flavor, and a little larger peppers than Marconi Red. I always have at least one variety of Marconis in my garden! I especially love to grill these and put them on grilled pizza.

Large and prolific. More comparable to a cubanelle than to a frying pepper. It does well here and is large enough to substitute for a bell pepper.
