Plants need light. They need light. Light is needed by plants. Plants need light. Say it with me: Plants. Need. Light.
Each window is going to be a little different in terms of how "good" a plant window it is based on:
1) Direction.
2) How big a view of the sky/access to light the plant has.
3) Things blocking the light.
Some plants are going to be more forgiving and flexible than others regarding their light access.
North Facing Windows:
Consider these LOWER LIGHT windows
Light will be lower intensity
Light will be less direct
Some contenders:
Pothos
Philodendron
ZZ Plant
Snake Plant
Good reminder here is that typically, the less light a plant receives, the less frequently it will need to be watered.
East Facing Windows:
Consider these LOWER/MEDIUM LIGHT windows
Light will be lower intensity
Depending on openness to the sun, these windows should get good morning light.
Some contenders:
Spider Plant
Peperomia
Prayer Plant
Scindapsus
Any of the Northern Window plants
Southern Facing Windows:
Consider these BRIGHT LIGHT windows.
Light will be high intensity.
This is typically where plants would receive the most light
*See my demo for an example of when this isn't the case
Some contenders:
Succulents
Cacti
Aloe
Some palms
Northern/Eastern plant suggestions (but maybe not sitting directly in the window)
West Facing Windows:
Consider these MEDIUM BRIGHT LIGHT windows.
Light will be higher intensity mostly in the afternoon -> "Afternoon Sun"
Second most amount of light after southern windows
Some contenders:
Crotons
Hoya
Fiddle Leaf Fig
Rubber Plant
Dracaena
Northern/Eastern plant suggestions (but maybe not sitting directly in the window)
Window Evaluation Checklist:
What direction is this window facing?
Are there major blockages outside this window (like trees, other buildings, awnings) or is it pretty open?
How much of the sky/sun do I see/feel when I put myself in the spot (as best as possible) where my plant would sit?
Use the suggestions in this guide to help you decide what window would work best for your plants!
