Mexican Oleander

The mexican oleander that we have in our garden is a really old tree, as you can tell from the bark. The ones i see in other gardens have oleander like barks. The leaves are similar, though much narrower.

Yellow is the most common color observed, but i have seen trees with flowers that are white or a white-yellow mix in the gardens of friends. According to my internet research, orange also exists. Mexican oleander is native to tropical America and is now commonly found in Chennai. The fruit is in small pods and can cause pain in the mouth, vomiting, cramping, abdominal pain, nausea and a host of other symptoms. (What else do you expect, it IS related to the oleander)
