The plant looks like a type of Asiatic Lily. Although you can grow Asiatic lilies indoors, they do better when planted outside. Lily bulbs, like all other plant bulbs, need to rest is a cool area for several months if you want them to bloom again. So after the plant flowers and the leaves die back, you need to dig up the bulbs, shake off the dirt, and put them in a cool area or in an unheated garage for 6-8wks. You can also plant the bulbs outside, in the ground, where they will cool in the winter, and bloom again the following spring.

Here are some care tips to grow an Asiatic Lily indoors.

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..

Water when the first inch or two of soil is dry. Be careful not to over water or to allow the the plant to sit in water. Many plants come in a decorative wrap. Remove this wrap when watering so excess water can drain freely from the Lily plant and allow the plant to air out before replacing the wrap. When buying an Asiatic Lily, avoid plants that have soggy soil, since that may indicate root rot.

It’s not necessary to fertilize while a lily plant is in bloom. However, once all of the blooms are gone, and you’ve placed the plant in a sunny spot indoors or planted it outdoors, fertilize about every six weeks with a slow release plant food.
