Very easy plant to take care. Only thing to be careful is when watering try and not to get the leaves wet.

When I said pest magnifier, I grow all of my plants outside. Instead of eating the plant, I get anything from moths to butterflies to spiders to even flies around the flower where they hide out. Beautiful plant, grows tall so prepare something for it to grow up along.

It was a class plant that I got to take home, we left it over a long, hot weekend with little to no shade when it was being watered once a day. A classmate gave it some watered down 5 hour energy and it seemed to be good. I do not recommend this though because for any other plant it would have died, this plant is friendly, but energy drinks are not:)

Can grow surprising large, so perhaps be prepared to train the stem along a pole or prop
