Gardeners' Notes:

Highly invasive in the Hawaiian Islands. Forms dense cover in the understory of mesic to wet forests, crowding out and suppressing the regeneration of native vegetation.

Beautiful grasses when blooming or not blooming. Had it growing in part shade. It took a hard hit last winter and i totally lost one plant, but the other has come back some. Moved some seedlings to full sun but so far they are not doing that well. Hope the mother plant comes back to its former glory. Will try some in a shadier area and see how they might fill in under some old holly.

Makes a very dramatic, arching clump for landscapes, but it reseeds very freely and can be invasive. I try to cut the flower heads off in late summer when it blooms, but I still get seedlings popping up within about 25 ft of any clump of Setaria palmifolia.

I bought four small plants from Revlar Farms in Aug 08. They thrived and have tripled in size. I do not water them too much, I do not want them to take over the flower bed. I am beginning to think I will need to move a couple of them with their babies later this fall. Beautiful when in bloom.

Grows beatifully in shade to part sun here in Pasadena (rather dry Zone 9b), with average to little water. Can get a little rangy in full shade, but will fill out when cut back. Beautiful understory plant - surprised it is not even in the Sunset Western Garden Book. Seems an ideal shade plant for the West.

Update: 2011

I find that it is not a choice plant for the West because it is not as suited to our dry summers. It gets big and sparse, unless you cut it back twice a year, then you have to deal with the blank spot in the garden. I underplanted it (yes, underplanted - it is that big) with Chlorphytum comosum (spider plant) to alleviate this problem. It is a beautiful plant. It is just better suited to the warm, humid East. That said, I still like it... read more
