Products > Impatiens sodenii 'Madonna'   Impatiens sodenii 'Madonna' - White Poor Man's Rhododendron     [2nd Image] Habit and Cultural Information Category: Perennial Family: Balsaminaceae (Touch-me-nots) Origin: Africa, East (Africa) Evergreen: Yes Flower Color: White Bloomtime: Year-round Synonyms: [I. oliveri 'Alba' ] Height: 4-8 feet Width: 8-10 feet Exposure: Light Shade/Part Sun Seaside: Yes Irrigation (H2O Info): Medium Water Needs Winter Hardiness: 30-32° F Impatiens sodenii 'Madonna' (White Poor Man's Rhododendron) - A frost tender shrub (often treated as a perennial) that can grow as large as 8 feet tall and 10 feet wide but is usually about half this size. It has a woody base and semi-succulent stems bearing 8 inch long dark green leaves in whorls. At the tips of the stems are the showy 2 1/2 wide white flowers (sometimes tinged pink in early spring) with slender spurs that appear nearly year round in frost free gardens. This large Impatiens does best in a well-drained soil in light shade or morning sun, but at the coast it will grow in full sun. Grows rapidly when watered regularly in warmer gardens to occasionally along the coast, where with a little protection it is tolerant of seaside conditions. Although it is hardy to only about 30 degrees F, limiting it to the nearly frost free areas (USDA 10-11), plants damaged by a frost will often resprout at the base and seed can perpetuate the plant as an annual in even colder climates. Prune annually after frost danger is past to shape and remove cold damaged stems then only tip prune the rest of the year; avoid cutting back hard as this discourages flowering. Native to the tropical East African highlands between 3,000 and 8,000 ft. elevation in Kenya and Tanzania.
