One of the more uniquely beautiful plants out there are the members of the calathea family. Varieties like Pin Stripe, Peacock, Medallion, and Rattlesnake are as visually stunning as their names suggest, and they make lovely additions to any plant collection.  And yes, they're pet friendly!

Calathea can tolerate a variety of light conditions, but do not like direct sunlight--it can scorch their leaves. Some of the more colorful varieties do require higher light levels to keep their colors and variegations vivid.

What makes calathea a little tricky is their preference for humidity.  When they are not in an environment with enough humidity, and if they do not get consistent watering, their leaves will curl up.  To keep this from happening, make sure your calathea is on a consistent watering schedule. When you do water it, hold it under a faucet or sprayer and give the leaves a good wash--and let the leaves stay wet.  If you have a spray bottle or mister, you can spray your calathea once a week or so.  Managing humidity is especially important if you live in a colder climate where winter temps mean drier air.  

As outer and older leaves age out, you can cut them off with a sharp pair of clean scissors or pruners. New growth will come up out of the center of the plant. You may notice that new leaves look different than the old leaves, with lighter or darker markings. Consider it an interesting aspect of the genetics of the plant, and see what happens.  

Always remember that plants are living, growing things and they will respond to their environment. Embrace the adventure of plant parenthood!
