Is it too late or too early to plant lily of the valleys?

I planted some lily of the valley pips in early march that I bought from Canadian tire by #easy to grow bulbs#. None came out. Then I did some research, you should soak them in warm water, plant in fall, etc. Wondering if I should try again. So is it too late to plant lily of the valley for flowers this spring / summer?

 

I don't know about that. But, if you want another way... have a walk around your neighbourhood to find a couple of gardens where Lily of the Valley grows. Bang on the door, or catch someone outside and ask if you could have a few bits. I'll bet the answer will be "Sure". It's tough stuff, and I think you could transplant it any time as long as it has some shade and stays moist.

...ours is in flower right now. We have to knock it back this year. It's taking over.
