An ornamental pepper that works well in containers, 'NuMex Twilight' fruits begin purple, transition to yellow, then orange and finally to red. This pepper measures up to 100,000 on the Scoville scale.
Growing peppers. Peppers hate nitrogen/commercial fertilizer. Wait until plants flower before fertilizing. Then spray leaves with 1 tsp of Epsom salt to 1qt of water (peppers need Magnesium to set fruit). Peppers also enjoy small amounts of potassium (wood ashes).
Can't hurt to try: Spray the plant with Epsom salts (1 teaspoon dissolved in a spray bottle of warm water (about 4 cups). That gives the pepper plant a boost of magnesium that is required at flowering time to produce fruit. Spray them again 10 days later and in a few weeks, you will have more peppers than you can eat.
