Kaner in India
Kaner is a familiar hedge and temple-garden shrub with showy flowers — Kaner कनेर (Hindi), அலரி Alari (Tamil), గన్నేరు (Telugu), ಗಣಗಲೆ ಹೂ (Kannada), അരളി (Malayalam), कण्हेर Kanher (Marathi). Nerium oleander is planted across Tamil Nadu, Maharashtra, Telangana, Andhra Pradesh, Gujarat, Karnataka on road medians and in gardens because it flowers freely and survives heat and drought.
Uses
The flowers are used as temple offerings in parts of India. Beyond that its uses are limited by a crucial fact: every part is highly poisonous. It is valued as an ornamental and a tough hedge, but should never be eaten and is best kept away from small children and livestock.
How to Identify Kaner
An evergreen shrub with long, narrow, leathery leaves arranged in threes, and clusters of five-petalled flowers in pink, white or red, sometimes double and lightly scented. Broken stems exude a clear-to-milky sap; slender paired pods release tufted seeds.
Frequently Asked Questions
- What is Oleander Tree called in different Indian languages?

- Is oleander (kaner) poisonous?
- Yes — Nerium oleander is highly toxic in all its parts if ingested, so although it is widely grown for its flowers, it must be handled with care and never eaten.
- Why is oleander planted on road dividers?
- It is extremely tough — tolerating heat, drought, dust and pollution — and flowers for much of the year, which makes it a popular low-maintenance median and hedge plant.
