Reviving this threa, what a great discussion! 1) Easy plant that you found really difficult - bird of paradise. my absolute favorite flower, gorgeous plant, but I can't seem to grow it in my area. rotted the roots of my largest, and I have 4 seedlings hanging in suspended animation... don't know, I just can't get them right. 2) Difficult plant that you found really easy - Persian carpet flower, Edithcolea grandis. I've heard they rot very, very easily (almost overnight) even at room temperature... I've had mine for a few months now and it's doing just fine. Hopefully I'm not speaking too soon, as it has not flowered yet. 3) A difficult plant that was such a disaster you will never try it again - Desert Roses. I was gifted a dozen seeds, and bought 3 six month old seedlings. Every seed germinated, but they all shriveled out of nowhere and dropped their leaves. The larger plants leaves yellowed and now they're a little shriveled and kind of doing nothing... very disappointing, won't be buying any more :( 4) An easy plant that you find so rewarding that you collect them/push them/get too excited about them - cacti, specifically Gymnocalyciums. Love love love their flowers, and most are just interesting to look at. Easy to care for f given the right conditions and very rewarding in the springtime!

Thanks, everyone! Hoovb, I think that's the one! The bigger leaves are a little bigger than quarters, and fat like jade plants. As they go down to the tip of the stem, they pretty thin and limp, I think it must have been lying on the floor there for some time. Hopefully I can revive it. Good to know its not cold hardy, as most of my plants live outside. I guess that one will have to move inside when winter comes.

Robin, Im not sure how man red edge varieties there are but I have this one with the variegated leaves (I just realized it's sandwiched between two other variegated plants in the picture, I guess I'm a little bias). And for the years I've had peperomia the thing I've learned is that they'll tolerate lower levels of light but are usually stagnant and can lose some color. Mine enjoy the sunniest window in my home which is south facing but in the city with lots of buildings so direct sun on and off throughout the day. **edit** I realized this is the Peperomia clusiifolia 'Jelly/Jely/Jellie'. As you can see, mine is not like most pictures you see with bright red edges, I think they vary among individual plants. I also rarely fertilize (truly neglected to be honest). Every once in a while I will mix some Miracle Gro liquid plant food in my watering can. I do use distilled water, although this is mostly for my calathea and prayer plants sake, I don't know if the peperomias care one way or another.

Brown spots on Peperomia leaves can be due to environmental stress, insect infestation, diseases, or nutrient deficiencies. Methods to restore Peperomia include changing the growing conditions, combating pests, and diseases. Adjusting watering frequency is also important.
