My grandparents who live in India had a tree growing in their backyard as long as I can remember. It flowered all year round and at any given time there were tons of orange-yellow blossoms on the plant. I know my grandfather planted his tree from seed too but he planted his much before I was born so I dont know how much time it took for the first blossom etc. That tree is now about forty years old! The average daytime temperature where my grandparents live is usually 88 to 90 and average nighttime temperature from 74 to 79. Winter is a little cooler but there isnt much difference between summer and winter temperatures. I dont think the plant requires much care under those temperature conditions.

It has a very beautiful fragrance and I always thought it is one of the most fragrant flowers . You can smell it from quite far away. Its a sacred flower for Hindus in India and grown in temples a lot. Hope this helps!
