Last year I grew 2 varieties of ornamental pepper.
One had green leaves with splashes of white, white flowers, and white fruit that turned orange then red. The other had purplish green leaves, purple flowers, and purple fruit that turned red.
I carefully (because the flowers were so tiny and delicate) removed the anthers from the white flower (seed parent), and used pollen from the purple flower (pollen parent). The pollination took and I had my seeds saved, no knowing what will happen.
This year I planted the seed and they grew, and here is the shocking result!
