Suja:

I thought that you knew all. ;-)

Erysimum or Cheiranthus allionii & contrary to what I told you it isn't tall or daisy-like - it IS long blooming & orange! I was confusing it with the Helianthus my friend is growing. She got both of the seeds from me & I got them in a swap. Sorry about the misinformation. Here's a link that should fill you in. I'm going to post this so others will see.

Here is a link that might be useful: Siberian Wallflower/Cheiranthus allionii @wildflowerinformation.org

That's it! You said wallflower, and I kept thinking windflower, which I knew was anemone, and therefore not what I had. Are we in a warm enough zone that it is reliably perennial? Not that there is any need to worry, 'cause I'm not good about deadheading, and will more than likely have plenty of seedlings.

And Mr. Wiseacre, you're off the Christmas list! HAH!

It's overwintered for my friend 2 years now.

I have more of a problem getting it to "oversummer". It doesn't like heat.
