Cardamine bulbosa, or similar. But that's just a guess. It really needs a shot of the leaves to lock down the ID.

I haven't looked up hippeastrum. I thought of amaryllis but highly doubt it bc the blooms on this bulb didn't match any amaryllis I've ever seen or looked up online. It had a more lavender pink to it and flowers didn't quite match. Honestly I looked up Crinum lilly and that's what I was thinking of to begin with ( but couldn't remember name) they're really common here in Florida and I saw a crinum lilly online that looked exactly like the flowers these bulb had but I could be very wrong ! if ur saying Crinums bulbs are a different shape than maybe it isn't a crinum lilly ?? I'll check the out hippeastrums though :) thankyou guys for all the info ! I was thinking crinum- it definitely seems it could be but if the bulb doesn't fit - u must acquit- lol - little bit of humor :)

"But no one has told me what the difference is between Prunus laurocerasus and Prunus caroliniana. No such clarification was posted. My original question was about identification of a tree. Is there some reason to believe that I have one, rather than the other? " It was properly identified by botanical name by Embothrium. Prior to that, just one of many common names was used for ID however that common name is often applied to both species. Prunus caroliniana is a native species that includes Texas as part of its natural range. It would be very unusual for Prunus laurocerasus to pop up spontaneously in your area but entirely natural for P. caroliniana to do so. It is also more tree-like in habit than Prunus laurocerasus, which is most often grown as a large shrub with no discernible trunk and the leaves present somewhat differently (smooth margins for one and slight serration for the other). As to the negative attributes you list, other than the propensity for P. laurocerasus being invasive in specific areas, they are just not serious enough to worry about.

I'd still go with springtails, even if the particular species you have isn't very springy.
