Xanthorrhoea
All are perennials and have a secondary thickening meristem in the stem. Many, but not all, species develop an above ground stem. This is rough-surfaced, built from accumulated leaf-bases around the secondarily thickened trunk. The trunk is sometimes unbranched, some species will branch if the growing point is damaged and others naturally grow numerous branches. Flowers are borne on a long spike above a bare section called a scape, the total length can be up to four metres long in some species. Flowering occurs in a distinct flowering period, which varies for each species. Flowering can be stimulated by bushfire, in which case it occurs in the next flowering period after the fire.

Thanks. I've seen them with long spikes before but I don't think I've ever seen the flowering part so tall. The bees were loving it!
That's a really nice series of photos, Dee.
I've never seen one flower before. I didn't realize the stalk was that tall.
