Iris or daffodil.....both poisonous! Especially dangerous where children might think everything in an area is to graze on, or where dense sprouts might come up for cutting.... Here in CA there are numerous wild bulbs of uncertain edibility and they sprout up right through sheetmulch and raised beds and whatever, into the cutting greens....I have to be vigilant to pick the long, grasslike leaves out from the handfuls of greens...
The people who originally built our place were bulb fanatics. Last year (first spring here) I gave away over 600 bulbs! They had tons of daffodils and iris (as well as every other type). The people after them and prior to us made a mess of it (graded bulbs everywhere, not knowing what was in the beds...scooped and dumped...gave up.) While a few can be useful as rings around a guild drip line, a lot (randomly) are bad for your land. I kept a few in specific rows until I can incorporate them into permanent guilds or around hugels. I do not find them difficult to distinguish from my onion and garlic chives; and, currently have an area where the grow side by side. I too, would not be inclined to allow them in a random interspersing of edibles. If only a few pop up, you can always just pot them as a patio plant, too.
Evildoers! Eat my justice! And this tiny ad's justice too!
