Thunderbolt

Thunderbolt is a modern American sweet pepper hybrid sold through Burpee as a large Marconi-type roasting pepper. It was already being promoted in 2016, when it appeared both in Burpee-linked new variety material and in a January 2016 newspaper gardening piece as Sweet Thunderbolt, placing it in commercial circulation by that year.

The plant is described as bold, high-yielding, and suitable for both garden beds and large containers, with a mounded habit and a mature size of about 102 to 114 cm tall and roughly 61 to 76 cm wide. Fruit are long, tapered, and distinctly Marconi-shaped, commonly reaching about 33 cm in length. The walls are repeatedly described as thick, crisp, and sweet, and the pods ripen from green to red. Burpee-linked material also highlights resistance to Tobacco Mosaic Virus and Tomato Spotted Wilt, which is a recurring part of this pepper’s marketed identity.

In use, Thunderbolt is positioned as a flesh-heavy kitchen pepper rather than a decorative or hot type. Live descriptions consistently place it in fresh eating, frying, roasting, and stuffing, with flavour and texture treated as its defining strengths. Its reputation in current circulation is built around the combination of very large fruit size, sweet taste, thick walls, and strong production, which is why it is commonly presented as one of Burpee’s standout long sweet peppers.

Major factual conflict: online results for Thunderbolt also frequently return Thor’s Thunderbolt, which is a separate hot Capsicum chinense hybrid and not the same pepper as this sweet Marconi-type Capsicum annuum.
