Hi there, does anyone know any good interior housplant packs, or like a like from where i can download them (for free)? would love to hear from you! 
@Ritterbecks Quixel Megascans has a good collection of house plants and house plant pots you can drag directly into your editor via Quixel Bridge.
Alternatively, check and keep an eye on the permanently free collections and monthly free collections in the Unreal Engine Marketplace as free house plant packs come and go occasionally.
