my default.. for all vines.. houseplants.. is that they grow up rainforest trees ... [i didnt say it was right.. lol.. this is how i 'think about it' for 'culture' purposes .. 'culture' being how you grow a plant ...] ... they have roots in the ground.. that stay very humid.. but with the vast canopy .. may never get a much rain ... [except for a brief rainy season] they climb up the tree.. capturing ambient moisture with large leaves.. and putting roots into the bark.. again.. little water for those roots.. etc... so when we think of a potted .. tropical.. or semi- tropical houseplant .... we would want media .. and watering ... consistent with such thoughts... and that.. for me.. would translate to a drink .. and then full drainage ... a second reason such work well as houseplants.. is because of how little actual sunshine gets down thru the canopy ... which is similar to house-level light ... as i said.. this is NOT science.. this is how i 'think about it' .. when i analyze.. what i might have to do with a houseplant.. now.. with the WWW .. you can do a few minutes of research as to its native habitat ... and you should be able to intuit what direction you should go ... [can you believe in the good old days.. i had to actually buy a book to learn this stuff] and a glass vase that holds water.. will not be the answer anywhere.. that is all i wanted to point out.. i did not address whether it looked good or bad.. or anything else ... just those stains on the glass ... until OP comes back and explains such .. there is no further concern ... and its winter.. no plant holds its old leaves forever.. and the extra low lighting of winter .. in the house .. makes some of the older weaker leaves fall off .. its natures way [and a forced air furnace sucking all the humidity out of the house doesnt help either] ... good luck ken

If you had small children who habitually ate plants in the yard, toxicity might be an issue... but then many plants are poisonous, probably including the lily you originally planted (at least many things in the lily family are poisonous). Tomatoes and rhubarb leaves are poisonous too, but most people don't worry about them. I'd say enjoy your plant. (As to how it got there, it probably came as a seed or weed in the pot you planted--I've had many pleasant surprises like that.)

"Weedy stuff." If it's in the lawn, try Weed B Gon Max. Then post a photo of whatever that didn't take out and we'll start identifying species and what to use to kill that.

Emily You are right about the names...I wish there was really reliable site with correct names and no synonyms! - but that is probably impossible. On top of that, many 'made-up' names just to attract ppl to purchase different-looking plants - and they are often just grown n different conditions. Tricolor has mostly green and yellow leaves, with occasional white/almost white: Mine get purplish color on leaves when outside, in lots of sun: Lemon & Lime have been also more greenish, but much more colorful in sun - below are pics of same plant (1st pic is when purchased): Blooms are of no help - they were white, just as 'regular' green jade or Hummel's Sunset. They all get pinkish as they age: Hummel's - Lemon & Lime - green C.0.
