The plants flower in three distinct colors: white, yellow and red. The flowers first appear in early May through the early summer in the Northern Hemisphere, and the fruit ripen from August through October. The fruit are typically eaten, minus the thick outer skin, after chilling in a refrigerator for a few hours. They have a taste similar to a juicy, extra sweet watermelon. The bright red/purple or white/yellowish flesh contains many tiny hard seeds that are usually swallowed, but should be avoided by those who have problems digesting seeds.
