New Guinea impatiens are annual flowers that come in various colors. These flowers belong to the impatiens genus, which is known for producing flowers in all shades except blue and yellow. New Guinea impatiens were discovered during a plant hunting trip in Southeast Asia. Impatiens are low-maintenance plants, making them ideal for gardening. Many impatiens varieties were accidentally introduced to Central and South America through trading ships from Africa.

New Guinea impatiens grow into compact, succulent subshrubs that can reach 1 to 2 feet tall by the end of summer. They have long and narrow leaves that come in green, bronze, or purple. Their flowers are up to 2 inches in diameter and come in white, pink, lavender, purple, orange, and red.

New Guinea impatiens prefer fertile and moist soil that is high in organic matter. They are more tolerant of sunlight than other impatiens, as long as their roots remain moist. It is recommended to add slow-release fertilizer to the soil before planting and to plant them after the danger of frost has passed and the ground has warmed. They should be spaced 9 to 15 inches apart.

New Guinea impatiens can be propagated through seeds or cuttings. Currently, only two varieties of New Guinea impatiens are available through seeds, which should be sown 10 to 12 weeks before planting outside. The seeds should not be covered, as they require light to germinate. Cuttings can easily root in 2 to 3 weeks.

Impatiens are best used in masses of color in garden beds and borders. They can also be clustered in groups beside garden features or planted in containers and hanging baskets. Other related varieties of New Guinea impatiens include Tango, which has fluorescent-orange flowers, and Sunshine hybrids, which come in various colors and have variegated foliage.

The scientific name of New Guinea impatiens is Impatiens species.
