A little investigation quickly identified it as "nutsedge."
From Texas Cooperative Extension:
Nutsedge, often called nutgrass, is really not a true grass, but instead a member of the sedge family. Its proper name is nutsedge or for you Latin lovers, Cyperus esculentus. It is closer 'kin to Papyrus (used to make the ancient writing paper of Egypt) or the ornamental Umbrella sedges, than to St. Augustine or bermudagrass. This African native plant has thrived and spread throughout the New World. Because of its ability to thrive and persist, most gardeners and farmers would agree that to know it is to hate it.
When a nutsedge shoot reaches the surface it forms a basal bulb, from which grow roots and thin, wiry underground stems with new tubers at their ends. In one year, the outward growth from one tuber has the potential to produce 1,900 new plants and 7,000 new tubers. Now you can see why it's so tough to control! If there is any good news it's that individual tubers do not last longer than 3 years (thanks a lot, right?).
For read the entire article visit:
It appears that the only way to control nutsedge is to use chemical pesticides such as Round Up and since I have pledged to keep my garden chemical-free, it appears that I am doomed to pull these bloody annoying little things out of the ground by hand or hoe forever.
I'd be interested to hear from other gardeners who have problems with nutsedge (you know how the saying goes: Misery loves company!) Or perhaps there's another weed that is the bane of your existence?
Let me know in the comments.
And now, lest you think my garden has completely gone to ruin, here's a shot of the self-seeded zinnia "Profusion" living up to its name in the island bed.
