Bitter melon, a member of the Curcurbitaceae or gourd family, has long been used for both culinary and medicinal purposes. Also known as Chinese bitter melon, pare, arsorossie, karela and mara, the bitter melon is a herbaceous tropical vine. Grown as a tender perennial, the fruit is harvested when green and cooked. The fruit is bumpy with a light greenish-white, waxy skin. The melon contains numerous seeds. Propagated from seed, bitter melon grows best in full sun. Provide organic compost and plenty of water. Protect the tender vines from frost. The majority of tropical vegetable seeds, including bitter melon, should be soaked in warm water overnight prior to planting. Soaking allows moisture to reach the embryo of the seed, starting the germination process.
Sweet and savory, the alligator pepper (Aframomum melegueta), also known as guinea grains, grains of paradise, atar and grani de paradiso, is part of the ginger family (Zingerberaceae). Easy to grow, alligator peppers like lots of sunshine, plenty of water and fertile, well-drained soil. A tropical perennial native to West Africa, alligator pepper reaches 5 feet at maturity and presents purple, trumpet-shaped flowers. The flowers develop into 3- to 5-inch long seedpods that are dark gray in color. Each seed pod contains numerous dark red seeds, prized for their unusual spicy, citrus aroma and pungent pepper flavor. When planting vegetable seeds, keep the seeds moist but not saturated. Seeds that are over watered rot and fail to germinate.
