I do not have a green thumb, and on top of that I've never been into having house plants. However, our house is big and I would like to fill in some empty spaces with a beautiful large plant. What do you recommend that can survive in a big space with lots of light? I'm open to all suggestions, just fyi, bi weekly care is best! ;)
My Monstera plant that I originally purchased at IKEA 6 or 7 years ago is thriving by my north-facing window. It's really fills a space well, as these plants naturally like to grow outward instead of up (I use a trellis to help it grow vertically). They don't need much care at all! Just one watering can full every week or two will keep it happy and growing.
If you're open to a hanging plant, my favorite one is my spiderwort plant. Really vibrant purple color and very easy to care for. I've also neglected a ponytail palm tree for years and it still enjoys being alive! They do best in bright light and not a lot of watering.
I'm a black thumb too. I try to stick to cacti and succulents. I had a fiddle leaf fig, but everyone always considered it a miracle that I kept it alive because they're (apparently to the greener thumbs) notoriously finicky. So I'm hesitant to recommend it because it might have been a fluke!
Azzizi or Z plants are notorious for lasting thru the black thumb conditions 😁. Water it once a month. It don’t care. They can get big and also be broken into smaller pieces.
Dracaenas or cane plants are also great with low care.
Pythos will grow down nicely or trail them across your wall/ ceiling.
Lastly, cut bamboo is very hardy and requires no dirt, just water and maybe some pebbles or glass bits to weight the vase down. I have a wholesaler I can acquire from in larger bunches if you want a vase or a more full!
Snake plants are really easy to care for, clean the air and are cool looking. Blue Poppy in Wedgwood is a locally owned plant store that has loads of gorgeous larger plants and the owner and her daughter are super helpful and knowledgable in the care of the plants they carry.
All the suggestions above are great, easy to care for plants! The key to keeping most of these alive is to water only when completely dry. Use your finger to test - stick your finger into the soil down to your first knuckle. If it feels even a little moist (or if soil is stuck to your finger), wait a couple more days and test it again. Don't follow a watering schedule as it will depend on your home environment. Also, "low light" plants will still need some type of light! They just die a much slower death.
If you are going to get live houseplants, consider also providing them with supplemental artificial light. There are some attractive lights designed for indoor plants. I'm reading the book "Gardening Under Lights", and it has some great examples. Also, if one of your motivations is for the plants to provide clean air, NASA developed a list of the top plants for this, and there are a number of plants on the list that do OK with low light. Snake plant is one of them, and mine is still alive after 5 years, which is impressive based on my houseplant track record...
I am a big fan of Snake Plants, Aloe Vera and ZZ Plants. I've had good luck with succulents that have been potted into old, antique ceramic dishware, too! Also, thanks for recommending Blue Poppy Shannon Garbaccio, I am hoping to do a floral cart this summer for my shop, so I'll look into them as a possible vendor.
Mandi Pacer Diep is the owner at Blue Poppy and she and her daughter run it together. They are very community oriented and are always looking for ways to be involved. I have no affiliation with the shop aside from being a big fan of it!!
