What is this HousePlant that Suddenly Bloomed??

I’ve had this houseplant for years and it suddenly started to get these gorgeous flowers. Can you tell me the name of the plant?
Thanks so much for your help. Love the site.

Hi Tracey,

Orchid Cactus Flower

Your plant is called an Orchid Cactus. This is a great easy care plant and will continue to bloom if you follow a few simple care instructions. Keep an Orchid Cactus a little root bound and it will flower more. Orchid Cactus need to rest for a few months in the winter, so don’t feed the plant and keep the soil dry during this time. Orchid Cactus need to be fed with a plant food high in potassium starting in late March through September. Orchid Cactus like bright indirect lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light. but no direct sun. Once the buds appear, try to keep light, water, and temperature consistent. If you move the plant or if it gets cold, an Orchid Cactus will drop all of its new buds.
