Loving Marconi Peppers – Red and Green!

We Love Our Marconi Peppers!

We’ve grown the Marconi Peppers (red variety), Capsicum annum, for three straight growing seasons. These Marconi sweet peppers come on a bit late with beautiful long green fruits that gradually redden as the season progresses.

We procured the seed from Baker Creek/,  and though slow to germinate and grow in flats, this pepper loves it in the garden. The catalogue write-up indicates 80 days to maturity, so getting them out ASAP after the last frost will help.

Marconi Pepper

  • Slow to germinate
  • Grows well in flats
  • Easy to grow
  • 80 Days to maturity
  • Grows up to 6
  • Plant ASAP after last frost
  • Plants do best with support*

*One pointer for growing the Marconi Pepper is to provide support as it grows. Ours are nearly six feet tall now and have done well with the “Florida Weave” method lacing jute twine about every two feet up the stem.

Growing Marconi Peppers

  • Press seeds into starter medium
  • Place seed tray on heat mat
  • Keep moist

The bottom heat pad helped all our peppers to germinate. We have the Vivo Sun brand of plant heating pads, and germinated them in our indoor greenhouse.

Green Marconi Peppers

The green Marconi Pepper is just as sweet—or sweeter tasting—as green bell peppers. Marconi’s are often used for stuffing, like the popular poblanos from Mexico, they’re great for stuffing and for chile relleno casseroles (see our recipes below).

Red Marconi Peppers

The ripened Red Marconi Peppers do much better for us than the so called red” bell peppers. The taste is quite sweet and suitable as a raw ingredient for salads and garnishing as well as cooked in any number of ways in stir fry, casseroles, and omelets.

Marconi Sweet Pepper Recipe

We made a delicious chile relleno recipe using green marconi peppers instead of the usual poblanos. We used this recipe from the We made two tweaks to this recipe:

  1. Did not pan fry first; placed directly into oiled baking dish instead
  2. We used mozzarella cheese sticks instead of shredded cheese
  3. We used gluten free bread crumbs, instead of flour, for the Chillie Relleons “crust”

Marconi Pepper Conclusion

Given all these attributes, three years of “field testing”, and the many positive ratings (e.g. Baker Creek’s on-line reviews), we recommend trying Marconi Peppers in your garden. If you have a small patch like ours, then it’s even more important to invest in a variety like Marconi.

Marconi peppers grow well, produce abundantly and have so many uses, both as a green and red vegetable.
