The marmalade bush (Streptosolen jamesonii Benth., Miers) is an evergreenshrub of the Solanaceae family that produces loose clusters of flowers gradually changing from yellow to red as they develop, resulting in an overall appearance resembling orange marmalade (thus the name). The sole member of its genus, it is found in open woodlands of Colombia, Ecuador, and Peru.
The stems tend to be tall and slender, with an overall height of 1-2 meters (3-6 ft). The leaves are ovate to elliptic, green to dark green, with a pattern of fine wrinkles. The flowers appear in late spring and last through late summer; they have a slender tube 3-4 cm long, with spreading petal lobes.
Hibernation: Your Streptosolen is still inside, but temperatures are already rising in March, so you should slowly start giving the plant a little more water.
But it is advisable that you take the Streptosolen inside at night if there is night frost.
Hibernation: If you live in an area where night frost may occur in early autumn, you need not be afraid that the Streptosolen will immediately die, because they are very good at surviving night frosts of minus 1 to minus 2 degrees Celsius.
