JoAnn, the bulbs at that link are dangerously tempting!
Y'all aren't going to believe this, but, we're moving and I'm moving *most* of the bulbs - again! Everyone I've asked for an opinion about it has agreed, they'll probably go back to being lost in mowed lawn if left here. Here's a list of bulbs I've found over the past few years, and will now be moving...
Amaryllis - red, found the first year I lived here
Lycoris radiata (red spider lily)
Daffodil
Allium
Oxalis (pink)
Crinum (haven't bloomed yet..., just guessing this is what they are)
Gladiolus
Liriope (not technically a bulb I think, but found huge chunks of it in the lawn)
Before mowing the first time (for those who haven't yet,) now is also a good time to check for bulbs foliage among the grass.
