The plant likes a lot of sun and is fine with some shade and has a mild fragrance that all butterflies seem to love. While taking this photo a swarm of monarchs, some whites and blue butterflies were circling around these plants. Fascinating to watch but difficult to capture on camera!

A great plant for your butterfly or moonlight garden. It is known as 'din ka raja' in India--King of the Day, and complements the Queen of the Night (Cestrum Nocturnum--'raat ki rani'). Planted near each other, the energies of these two plants help each other to grow and bloom wonderfully well. New Delhi's climate seems to have changed over the past three years coming closer to zone 10b rather than 10a. All flowering plants including trees are flowering about 3 weeks to one month earlier tha... read more

I bought this plant from Top Tropicals, their website doesn't say it's poisonous, I should've looked here first! I have little kids so really didn't want this plant around after I received it and read that infact it was poisonous, but I said I'd put it out of reach and keep and eye on it, if it was outstanding when it flowered and really did smell like chocolate I'd keep it. It flowered the other day and I must say, if I had no knowledge of it smelling like chocolate, I would not have guessed it, I guess it does very faintly if you close your eyes and really imagine it. I personally am a little disappointed and was hoping for more of a richer smell. It is very fussy with wanting water, I pretty much have to water it every day here in Florida 9b, it is in a small pot so maybe that contribut... read more

After three years in a one gallon pot 18" tall mine bloomed. The scent is like fine chocolate cocoa, delicate but distinct. It has dozens of tiny white tube flowers and the smell has become one of my new favorites. It for sure, will not escape here in Long Island. It is too bad it is invasive, but for pot culture in a colder climate I would recommend this one. Most of all anyone looking for a chocolate smell try this plant! Mine has hated to be to dry, the leaves will droop and dry up pretty fast then drop. It has always recovered and looked better than before. Tough, maintainable, chocolate smelling numerous white flowers, what a plant!

I have not grown this plant so I am unable to rate it other than give it a neutral rating. Other common names for this plant include willow jasmine, wild jasmine, hierba santa, white day-blooming cestrum and white chocolate jasmine. It is an evergreen shrub or small tree that has, having escaped cultivation, become widely distributed and naturalized in Florida, Texas and California and grows in Hawaii after being introduced from the West Indies. In Texas, its natural habitat is in the Edwards Plateau region. It is considered a serious threat to natural areas in south Florida and can form dense thickets. It is most commonly found in dry soils, but benefits from even moisture. Although it will take full sun, it grows best in part shade. It is supposed to be hardy to Zone 8.
