I think this may be a sage, from pictures I saw here it looks like a pineapple sage, but it never bloomed since last May. It was quite tall and I didn't cut it last year, not until a bit ago...the foliage and stems looks sick/dead and I saw all this new growth inside. It had grown to about 4 ft...just a green thing that suffocated other plants around it. Now that I cut it, it looks healthier, but I still don't know what it is.
