I recently purchased a blue thunbergia and this is a new plant to me ... but oh my god beautiful!!! I have no clue what it likes and does not like. Also II noticed that the buds develope a sticky substance...almost like honeydew from aphids .. but it is only on the buds. Have inspected the entire plant and have not found any time of bug life =) Can someone please tell me what this is? Does the plant require ants or other pests to bloom thus creating the sticky substance?
Thanks so much
