The canary bellflower is an iconic and endemic species to the canary islands where it grows in the high and moist laurel forest down to the more moist areas of the Thermophile zone. The plant makes scrambling and climbing annual stems from a perennial tuber.
The flowers are very large for the Campanulaceae family and most often bright orange to red which attracts the local birds such as the Canary Islands chiffchaff (Phylloscopus canariensis) that pollinate the flower.
