What are the right conditions? I had a Eucharis grandiflora for years, and could never get it to flower. I’d love to try it again. What sort of light do you keep it in? What kind of fertilizer, and how often? Any other tips?
To be honest, I don’t really know. Mine sits under a NW facing window. It doesn’t get much direct sunlight but gets a fair bit of indirect light this time of year. Through fall and winter it doesn’t get much indirect light either. Maybe the shorter day lengths promote the flowering, as I am far enough north for there to be big differences in day length through out the year.
Temperature is another thing that can induce flowering in plants and could play a role with Eucharis. During the heating season the night temperature in our house is set to 60 degrees. It may be that the cooler temperatures in our house in the fall induce the flowers, which would explain why mine usually bloom in November, as our heating season generally starts in October.
I suppose I get around to fertilizing it about every 6-8 weeks. I use higher N this time of year and something with higher P in the fall. I don’t like to overdo it with the nitrogen because I do want to get flowers. I try to keep the soil moist, although it does dry out occasionally when I don’t get to water things as often as I should.
As a hijack, I have pretty good luck getting houseplants to bloom. Right now I have some Agapanthus blooming along with the Clivia I mentioned earlier and my Cereus had 3 flowers open last Friday (they are only open for one night, but are spectacular flowers). Not bad for living in Wisconsin.
You have an Agapanthus blooming indoors, in Wisconsin? Wow. Good for you.
Thanks so much for answering. 
Since the lighting and fertilizing is not much different from what I did, maybe the cool nights are what does the trick. Back when I had mine, I lived in an apartment where I had minimal control over the winter heating levels. I’ve got a spare room in my house now where I put things that like it cool in the winter, so maybe that will work.
I’m not the least bit surprised at what you can grow and bloom in Wisconsin. I’m in Illinois, maybe a couple of hours southeast of Madison, and I’ve done better with my houseplants over the four years I’ve lived here than I ever have.
I had one get cold-killed, I thought (our only cold snap this winter and I forgot to bring it in off the patio), but I trimmed all the dead off the poor thing and it came right back!
You’re welcome. If I were you I’d give Eucharis another shot. I don’t know if something with the common name Amazon Lily would respond to light and temperature cues but you never know. Something induces mine to flower at the same time of the year. The flowers are nice but I think it looks good without them too, which is why I brought it up in this thread.
I’ve moved around a bit (Illinois, Tennessee, Missouri) and I guess I have had as good luck getting things to flower here as I have anywhere else I have lived. My jade plant doesn’t flower any more but that is because it is too big to put outside now (probably 4 feet wide so it won’t fit through any doors, and is very heavy).
Thanks for all your input and comments, folks.
Here’s what I ended up with:
Top 5 absolute easiest:
Aloe
Dracena
Pothos
Sansevieria
Spider plant
Ten others that are incredibly tolerant:
Aspidistra
Chinese evergreen (Algaonema modestum)
Christmas cactus
Dieffenbachia
Jade plant
Peace lily
Philodendron
Pony-tail palm
Purple velvet
ZZ plant (Zamioculcas zamiifolia)
Dieffenbachia is tricky. Very easy to grow if it’s healthy, but dieffenbachias are susceptible to rot, and if they get it, it’s hard to cure. I’ve lived places where they grow like crazy, and I’ve lived places where no matter what I do, I can’t keep them from rotting.
I’d urge people to get dieffenbachias only from very reliable sources, because once you get whatever bacteria or virus that causes rot, it’s liable to kill every dieffenbachia you bring in your house.
Seconded. Swedish ivy* is unkillable. In fact, it’s so unkillable that if a bit of it escapes whlie giving it a haircut and falls into your dieffenbacchia plant it will take root. If you give Swedish ivy a haircut and layer the bits on top of well-watered dirt, it will root - you don’t even have to stick it into the dirt, just set it on top. If your Swedish ivy is brown - not just wilty, but actually brown - it will come back to life if you give it a haircut and water it. If you overwater it, it grows FASTER. If you neglect it enough, it might actually produce flowers.
I strongly recommend Swedish ivy for every brown thumb. It’s like the zucchini of the houseplant world.
*Neither Swedish nor ivy. Discuss.
African violets can be easy or not, depending on conditions. So in my book that makes them “not totally easy”
They hate to be overwatered, for example. And they get root rot easily.
My favorite houseplant, by the way. I have about 30 of them.
OOps - forgot I was in an old thread. Sorry guys.
Draecena and Dieffenbachia are the only two plants I can keep alive. Even my corn plant perished due to unknown causes.
I’ve just been given a peace lily and I’m taking bets as to how long it will last.
Rosemary seems to be next to impossible to kill. I’ve got one growing in the office. It gets nothing but fluorescent light, minimal water, extreme heat conditions (both winter AND summer), and people taking sprigs of it all the time. The damn thing has grown taller than my 20" monitor and full enough to warrant its own shelf.
Spider Plants are very easy, and they’re ridiculously easy to propagate.
I’ve killed a Jade plant. They’re not hard, but they’re not automatic, either.
Cactuses/madagascar palms are pretty easy.
Hm.
I received a rosemary plant last year as a gift. It began its decline pretty much as soon as we got it 
And we did take decent care of it. Maybe the one I got was traumatized by being shipped to me.
Spider plant, spider plant,
does whatever a spider plant does.
Can it grow, into a vine?
No it can’t, it’s not a member of genus Vitis or any similar climbing or trailing plant!
Look out, here comes the spider plant!
Just for the record, the coleus mentioned in the OP is still alive (4 months later).
Thanks twicks.
Yay! (you’re welcome!)
Despite their exotic appearance, Begonias (fibrous rootes, not the landscaping tuberous rooted types) are extraordinary houseplants. Although not inthe constant neglect category, a good angel wing will be quite forgiving and reward the caretaker with both beautiful foliage and flowers. The easy rooting is a great way to build a collection by liberating material from plants you desire.
