By our calculations, you should look at sowing Hybrid Red Popper about 60 days before your last frost date.
Hybrid variety created by crossing several other varieties. See comments under Folklore box for speculative info about its breeding.
Speculation about ancestry of this hybrid:
Probably has ‘Klari Baby Cheese’, and ‘Miniature Yellow Bell’ in its lineage. The child of those two was then crossed with who knows which hybrid(s)…Likely with ‘Baby Belle Sweet,’ which has good disease resistance.
