Gardeners' Notes:

Neutral xyris On Jun 16, 2004, xyris from Sebring, FL (Zone 9b) wrote:

I was quite surprised to find this very small pipewort added to the database this week. The plant is only about 10 cm or less tall in flower, and each flower head is only 3 to 4 mm across. The leaves are so small as to look like a dark bluish-green clump of moss. I described this new species in 1993, based on seeing it at about 10 sites in the central Florida panhandle, where it is hundreds of miles south of its nearest relative (Eriocaulon aquaticum - sometimes referred to as E. pellucidum or E. septangulare). To my knowledge it has never been cultivated by anyone.
