Botany

[edit]

The plants possess leathery leaves, ranging from 3 to 6 inches in length, and produce large clusters of tinyflowersin the summer. Members ofIxoraprefer acidic soil, and are suitable choices forbonsai.It is also a popular choice for hedges in parts ofSouth East Asia.In tropical climates, they flower year round and are commonly used inHinduworship, as well as inayurvedaand Indianfolk medicine.

InBrazil,fungal speciesPseudocercospora ixoricolawas found to be causing leaf spots onIxora coccinea.[8]Then in 2018, inTaiwan,during a fungal study, it was found thatplant pathogensofPseudopestalotiopsis ixoraeandPseudopestalotiopsis taiwanensiscaused leaf spots on species ofIxora,which is a popular garden plant in Taiwan.[9]
