I recently bought a small tropical houseplant, but I don't know what it is. It has almond-shaped, slightly waxy, dark green leaves that have veins ranging from red to pink and yellow. The plant is about 8 inches wide and tall, and leaves are about 4-6 inches long. Does anyone have any idea what this plant might be? Care tips are also welcome! Thanks (I have included two photos, but I am afraid the quality is not very good.)

Looks like a Croton. I'm not sure what variety.
Maybe this one. Croton (Codiaeum variegatum)

@mes Try not to over water it if you keep it inside over winter. And Welcome to ATP!

Thank you! I have read that in general, crotons need to be watered only when the top of the soil in the pot is dry... Is this true of all varieties?

Well, "scientifically," you should stick your finger into the pot to check for dampness. Indoors, the top of the soil may dry out a bit, but be really wet under an inch or so. It's easy to overwater in winter. Also, don't be too concerned if your croton drops a few leaves while indoors. Cut back on water if the leaf drop is severe. Don't know what part of the country you're in, but you may want to set the pot outside during the warmer months. It will be happier on the patio.

Great, thanks for your help! I may put it outside in July and August, but it will be mostly an indoor plant, as I live in Ontario :).
