I like cacti, they are easy to take care and you can water them every 1 or 2 weeks. They are beautiful in their own way and unique too. And you can combine in one big vase, cacti and succulents, they will turn great and fassinating 😊
Oh I like snake plant too, it’s good for the air in the room, take them in the corner in the room, and it can be a decoration too 😊
I love a lot of plants so I'll stick to my favorite which is the giant sequoia. We have several groves of the spread around the Sierra Nevada area of California with the most famous ones being in Sequoia National Park. Walking among them is amazing.
My favourite ones are Quercus robur aka oaks (I love them), Castanea sativa (chestnut tree) and ferns, specially Driopterys filix-mas and Athyrium filix-femina. There're a lot of them where I live and they makes me feel like in an ancient forest!
