Q.Money plant
I have three plants, one with green leaves and two with green leaves with red tips. Is this male and female and, secondly, one of the red tip plants flowered this year. Is this normal? If so, do I cut the flower stems off to enable further growth? The plants are five years old and are cuttings from an original plant.

A Jade Plant may bloom in spring with a white to pink flower cluster.
You can dead head the flower stem when it is done blooming.
The red tips on the stems is a natural color pattern on the Jade Plant.
There are color and leave variations to this plant.
Here is a link with care information.
