Patchouli plants-that kind of grabbed my interest because, strangely enough for someone who has lived in SF most of her adult life, I never really thought about where that patchouli oil comes from. Do the plants give off the odor?
Well, I did exactly zero research on these plants-and I am far from being a master gardener, but were I in your position I would try to find out as much as possible about the plants-starting with the genus and species, because often there are several species of a particular genus-take the genus Viola. Some of the species are not even violets, but pansies, so it's kind of important to find out as exactly as possible what kind of plant you are dealing with.
To my eye it looks like a vine that has been tacked up on the wall, rather than a tall plant in the sense of a hemp plant (male) a friend had that grew over 7" tall (providing no intoxicants, but being pretty anyway). Also, unless it's a trick of the camera angle that container looks really small-I am not surprized the plants are tipping them over. Before cutting them back, find out A) If this is a vine, in which case a hanging pot may be a better choice or you can train it around stakes and B) If you can't tell from the soil it's in now, then find out it's preference so you can re pot them properly. Obviously they are happy with the current soil, try to copy it when you get a bigger pot. If you are not going to hang them, a nice, clay pot would be nice.
I wonder of they are meant to flower?
Sounds like fun....
I gathered some seed pods the other day and I have no clue what they are. I am going to plant them and see what comes up...maybe it'll be something good, maybe not. It's all one big biology experiment to me!
