And let's not forget Scilla. Yesterday was the first time my 10-year-old son expressed disgust at my garden when he passed a large sweep of bent over Scilla leaves. And today I yanked out a couple hundred deeply-embedded bulbs of a fall-flowering Scilla species. Anyway, what do you think? There's a poll on the right side of this page. So far two people have contributed (one being me). If I don't get a couple more participants soon, I will remove the poll to avoid further embarrassment. (Poll was pulled, or pull was poled, whatever: four responses does not make a proper population statistics-wise).
Speaking of plants that spread, this weekend is your last opportunity to go after garlic mustard. It is bolting, fast! If you pull it up any later you'll have to bag it since it will continue to bolt and set seed even though you've ripped it from the earth. Ditto if you opt to spray it with Round-up.
