Cycas Revoluta or the Sago Palm is a beautiful easy care houseplant with a mischievous twist that easily fools people in three ways. Firstly, despite its common name of "Sago Palm", it's not actually a palm because it's a Cycad (although the care requirements are similar).
Secondly the Sago Palm has a reputation of being a modern indoor houseplant (which it most definitely is). However in truth, as an outdoor plant, its been around for million of years and so it's actually one of the oldest plants you can grow as a houseplant.
The gold standard for most houseplants is bright light but no direct sun and that's true for the Sago Palms. Too much light will cause damage to the leaves. If you provide too little light it will not show negative consequences for quite some time, but for the plants long term health, poor light levels also need to be avoided. So bright light with no direct sun should be your aim.
The trunk and fleshy leaves will store some water so Sago Palms do well with fairly long spells of no watering. However they're not a true succulent so will perish if they're never watered.
The real danger for these houseplants is overwatering, too much will encourage rot and that's what you need to be careful of. So water well and then don't do it again until the soil is almost completely dry. In Winter, when there is less light and temperatures are cooler you'll find you only need to water occasionally.
