Help With Identifying My Plant

I have this plant that belonged to my grandmother, who recently passed and I know nothing about it. I do not know what type of plant or how to care for it. I reported it into a larger pot but the leaves are turning yellow from a dark green.

Hi Angela,

Your plant looks like a Clivia plant. Here is one in full bloom.

Clivia Plants bloom for about 4 weeks during the late spring and early summer when the weather is warm and the days are long. Clivias are large plants that can grow 2-3 feet tall and almost as wide. Planting a Clivia Plant in a heavy clay or ceramic pot, prevents it from tipping over. The older a Clivia Plant gets the more beautiful it becomes. Your can read all my care tips in the Popular Houseplant section of the website.

The plant is turning yellow because it is to wet. You should have left the plant in a small pot so the soil could dry out quickly. You are over watering, the soil is staying wet too long and damaging the roots. Water a Clivia plant well and then allow the top 50% of the soil to dry out before watering again. Clivia Plants prefer to be on the dry side. 

These plants are considered poisonous and should be kept away from pets and children. Read more about common houseplants that are poisonous in Don’t Feed Me To Your Cat! A Guide to Poisonous Houseplants.
