Probably. Bulbine glauca sometimes grows in grassy areas, though usually in rocky areas. I need to see a good in focus cliseup of the anthers in the muddle if a flower to make sure it is one or the other. The colour of the leaves and stem could be either.
Thank you Betty/Don. I will return to the site some time this week and try to get the image that you have described. The site is a rocky ridge, though the plants are widespread, not just associated with rocks.
