Impatiens auricoma 'Jungle Gold' is a perennial species of Impatiens with the original species coming from Tropical Africa. The dark glossy green leaves can reach up to 8 inches (20 cm) long. Plants can reach from 15-18 inches (38-45 cm) tall. They are an outstanding plant for shady areas and can be grown in containers or the landscape. We grew this species for first time this year and we are very happy with the results. Not only do they handle our very hot summers well here in Oklahoma, but they have continuously bloomed in 10 weeks from seed. If you are a fan of Impatiens in general, I recommend this species.
Blooming: In the greenhouse, the plants have bloomed continuously since they were 10 weeks old. The yellow-orange flowers are held above the foliage and at a glance resemble orchids. Individual flowers are approximately 1.5 inches (3.8 cm) long by 1 inch (2.5 cm) wide. Very showy!
Culture: Impatiens auricoma 'Jungle Gold' need partial shade to full shade, with a rich moist soil mix. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 1 part loam to 1 part sand or perlite. For each 0.01 cu yards of soil mix we add 1 cup of hydrated lime to adjust the pH, and 1 cup of 14-14-14 Osmocote slow release fertilizer. The pH should run about 6-6.5. The plants cannot tolerate drought, and therefore should be kept moist at all times. We fertilize weekly with a balanced fertilizer diluted to one-half the strength recommended on the label. During the winter months, plants grow and bloom just as they do in the spring and summer. Water is somewhat restricted, but the plants are never allowed to dry out thoroughly.
Propagation: Impatiens auricoma 'Jungle Gold' are propagated by cutting and from seed. Seed obtained from Park Seed (our source) germinated in 7-14 days from sowing.
Impatiens auricoma 'Jungle Gold' was featured as Plant of the Week November 9-15, 2007.
