5" Philodendron Imperial Green
What I need to be happy in your home:
Light: Philodendrons typically grow best in partial sunlight. They naturally would get dappled light under a tropical canopy, not direct sun. Indoors, set them up by a window that gets bright, indirect light. Too little light can result in leggy growth with lots of space in between the leaves. But too much light can cause many of the leaves to turn yellow at the same time. (Only a few leaves yellowing is typically just normal aging.)
Water: These plants generally like a moderate amount of soil moisture. Water whenever the top inch of soil has dried out. Both overwatering and underwatering can cause the leaves to droop, so gauge when it’s time to water by the soil dryness and not necessarily the leaves. Philodendrons don’t do well sitting in soggy soil, as this can lead to root rot. The non-climbing varieties tend to have a little more drought tolerance than the vining species.
