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

There's no rule saying you can't mix vegetables and ornamentals in the same garden. Furthermore, some gardeners line out ornamentals in the vegetable garden while they bulk up or until space becomes available elsewhere. Providing each has sufficient space and ornamentals do not interfere with cultivation and harvesting there is no problem.

The leafy one looks like a Senecio. If it has a yello daisy like flower, it is. The spikes one is a Deuterochonia, previously called Abrometiella. Mir is Avery spikey bromeliad, and grows like a succulent rather than like the soft leaved bromeliads.
