Description of Sunset bell / Chrysothemis pulchella:

Sunset bell tender tropical perennial belongs to the Gesneriaceae family. this plant’s also known as black flamingo and copper leaf pulchella. And the scientific name of the Chrysothemis pulchella. This plant is native to Brazil, coastal areas of the southern Caribbean, and large areas of Central and South America.


The green thick and succulent stems are usually up to 1.5 foot tall. One of the characteristics of the sunset bell plant is that it has only one main stem. The stem does not branch. The stem of the plant is flexible and grows by massing the soil and the tip of the stem is upward. Nodes are formed along with growth and new leaves emerge from these nodes. And the stem of the flower emerges from the base of this leaf. And as this stem grows, it divides into multiple parts to form a flower cluster.


The upper surface of the leaves is bright copper grey, uneven, and covered with very fine hairs (which are not easily noticed). The underside of the leaf is purple in colour and the veins are prominent. And the edges of the lanceolate broad leaves are Saw-Toothed and very slightly wavy.


The yellow flowers begin to appear in early spring and bloom until the dawn of winter. One of the big reasons gardeners are attracted to the sunset bell plant is its brightly coloured flowers. Yellow flowers bloom within dark orange sepals. And the two small red vertical lines on the yellow petals multiply its beauty. But the yellow petals do not last more than one to two days. However, it does not detract from the beauty of the plant. The beautiful bright orange-coloured sepals are long-lasting and bring a different level of beauty to the plant.
