Worthwhile experiment · Grocery-store growing
Collect mature pepper seeds, dry them properly and start them for a Florida garden without promising an exact copy of the original pepper.
The direct answer
Seeds from a fully mature grocery pepper often germinate, but hybrid fruit may not grow true to type. Red, orange or yellow peppers usually contain more mature seed than green peppers, which are often harvested before full ripeness.
Florida timing
Peppers need warm soil but can struggle to set fruit in extreme heat. Central Florida gardeners commonly start seed well before the spring planting window or begin again for fall.
Gather before starting
Step by step
Choose a sound, fully colored pepper and label whether it was sweet or hot.
Wear gloves for hot fruit, cut it open and scrape mature cream-colored seeds onto a dry plate.
Discard dark, flat or damaged seeds and dry the rest in a single layer for about a week.
Sow seeds one-quarter inch deep in moist mix, two per cell, and keep the mix warm rather than soggy.
Move sprouts under strong light immediately and provide gentle airflow.
Thin to one seedling per cell and pot up before roots circle tightly.
Harden plants gradually, then transplant after cold risk when nights are reliably warm.
Keep hot and sweet peppers separated if saving seed from the next generation matters.
A green bell pepper is usually an immature fruit, even though it is perfectly edible. Seeds from a fully colored pepper have had more time to develop.
Dry seed away from direct sun and store only seed that is completely dry.
Pepper seed can be slower than tomato seed. Warm mix helps germination, but once seedlings emerge they need strong light close enough to prevent weak, stretched stems.
Do not compensate for poor light with extra water. That usually creates softer growth, not stronger plants.
Commercial peppers are frequently hybrids. A seedling may make excellent fruit without duplicating the size, shape or heat of its parent.
If predictable results matter, compare the experiment with one packet of a named cultivar suited to Florida.
