Yes, bulbs come through it no problem. It is sort of a loose mat which makes it possible for bulbs to poke up through it. A few weeds make it up through it as well, but that's about it.

in a decade or so.. it will no longer be a 'loose' mat..

it can also become so dense.. that water might not get successfully thru it.. to bulb depth.. for long term health of bulbs ...

with those caveats.. knowledge.. go for it.. so what if in 5 years.. the bulbs fail ...

one think to think about.. is what the yellowing bulb leaves will look like.. for half the summer.. might ruin that beautiful sliver foliage ...

I'm planting lots of it. It looks so sweet and innocent, but after reading this post I'm starting to worry. lol
it grows pretty low, so it shouldn't harm surrounding plants...right?
I have it next to shrubs in one garden and it seems fine so far.

I mean it's low when not flowering.

I have lots of it too. What specifically are you worried about? It spreads like mad but it pulls out really easily. When it goes beyond its bounds I literally grab the foliage and just rip it up. That is also how I deadhead it. Sounds crazy but it works perfectly.

I've had it for 10 years and it never does make a dense mat for me. It does make a continually-expanding loose mat though. I would not rate this plant as 'innocent' with the way it self-seeds, but it is still totally worth it. So don't worry! :)

I'm the type of gardener that sees something I like, and plants it everywhere!
I received some Laura Bush petunia seeds a few yrs ago and poof! My yard is purple lol.
I still love the LB petunias but they attack my other plants.

this is a planter my daughter filled with snap dragons, lobelia, marigolds sweetpeas and one tiny LB petunia. I cut it back once to give the other plants a chance but she grew right back.

That's a beautiful petunia. If you gotta have an overly pushy plant, at least it's a pretty one!
