substitute for dracaena spike plants
I typically plant a lot of flower containers and many of them have the ubiquitous dracaena spike plant. I'm looking to mix it up a little bit with some other plants that have a similar growth pattern (same height, upright, preferably "grassy") I have containers in both sun and shade. A bonus would be any plant that I can easily divide or quickly propogate to get additional plants. For instance, I usually separate a 4" creeping jenny into 4 separate plants which saves a fair bit of money. Anything that meets most/all of those descriptions? Thanks in advance for your help!
