I like unusual plants (why I like some succulents) I also like a plant that looks neat and well seated in the soil, but then I also like overgrown out of its pot and growing all over - so I think I like extremes. I love my haworthias right now because many of them have what's called cathedral tips, meaning that they are transparent so you can see through them!! Its an interesting aspect of that plant! Aloes I like because they almost seem to be dancing in slow motion - reaching from their pots and stretching, I don't notice other plants doing this like aloes.
Its fun reading what inspires others about plants... and yes, I am on a budget so I have to not go to crazy, and I have space limitations so that keeps me in line even better than the budget thing (Paypal just increased my credit amount- Great, now need more willpower again!)
