Im usually in the aquatic plants forum but I need some help on some grasses. I am wanting to use either the elijah blue or the boulder blue in containers in my cacti garden which is on the side of my pond. Reason for the containers is I want them higher than ground level which is where I have succelents and cacti. I don't want grasses that get too tall and are messy. From what I have read the two I have mentioned stay small. I just have never used grasses before in my landscaping and would like your opinions on how one of these two might look for what I am going for - which is a backdrop of sorts for the succulents - the pond is half above ground and has stone as the wall which everything will be in front of. Thanks for any imput or other ideas on grasses.
