What I'd like to be able to keep alive indoors and what will actually cooperate are two different birds...er...plants. I'd love to have tropicals and ferns and orchids. Instead I have several pothos and a sickly palm and...a couple of other totally bland growies.
My indoor plants don't get enuff light nor heat- 60* caves to keep out 109* days just doesn't keep a plant healthy. The indoor plants I have are well dried and/or stored in jars with lids (herbs). My vote was no indoor plants.
I chose "other'. I love tall ficus trees, giant monsteras vines clinging to a support, and myriad philodendrons designs with leaves of ever conceivable shape and colors ranging from bright, spring green to bright red and on to a deep, dark red black. I love Chinese Evergreens, diffenbachias, and really pretty much every tropical plant nature has given us. I am also quite fascinated by cacti & succulents, love the bold, statuesque appearance of tall, multibranching columnar cacti like some cerius varieties. I also love many other members of the cacti & succulent group, love aloes, agaves, and echeverias, each statuesque in its on way. At the same time, I love the gracefully arching beauty of large, verdant ferns dripping down between the various trees and vines growing upward, together forming a sort of living window cover.
In addition to all of this I have a special weakness for African Violets and episcias, especially the ones with unique, multicolor, ruffled, & variegated leaves in shades like green, yellow green, yellow, pink, red, & tan.. While I only have a few large philodendrons at present - and keep them outside year round, pot and all - at one time I had amassed enough for a veritable 'green' wall of large plants growing up from the floor interspersed with ferns and vines draping down from the ceiling. At that same time, I had a large collection of African Violets perched on glass shelves suspended before full length windows in a small dinning room with sky lights and celling to floor windows on 3 of 4 sides, a perfect home for light loving violets. These days, for now at least, I've moved my plant operations out of doors where I grow the usual outdoor varieties like roses, hydrangeas, lilies, and so on. Bottom line, while I don't currently have that huge group of indoor plants anymore, I am still unable to choose between tropicals, cacti, and gesneriads. I need them all.
I voted tropical foliage because that is what I have most luck with. Ficus benjamina, several different Draecena, Sanseveria, Pilea, Orchids, Palms, and a Ming Aralia, just to name a few. Though I do also have a couple of African Violets that are doing better than I expected them to. LOVE having an indoor garden!
To me, nothing beats philodendron giganteum. Give it some light, some water and some fertilizer and it just grows. Gotta love it. OK, as its name implies, it gets BIG, but one shouldn't need a magnifying glass to see your plants.
I voted "other" as the best sellers are the low maintenance plants. ZZ Plant (Zamioculcas zamiifolia), Aglaonema, Corn Plant (Dracaena fragrans 'Massangeana'), Dracaena fragrans 'Warneckei', Golden Pothos (Epipremnum aureum), etc. People don't want to be bothered with high-maintenance plants.
I voted "Other" because I do have a few plants that stay in all the time (cuban oregano and a few succulents), most of my plants spend part of the year outside. In the Winter, I have palms (metallic, balloon and fishtail), a couple of philodendron, and citrus (key lime, mexican thornless, Clementine) in the Sun room. I do have a greenhouse, so they could go in there, but I like the green in the bleak days of Winter.
