I don't know either, but would love to know, if you ever find some.

Have you looked in Garden's North web cataloge? Look under Perennials. I believe I saw it listed.

I have some dying flower heads, and possibly some slips... let me know if I have something you'd trade for. I'm really looking for Campion rose and/or alba.....

I'm looking for the Strobilanthes dyerianus...........the one with the colourful leaves. I got stuck with atropurpurea last year, and it looked like a potful of weeds.

Hi,

I've never seen seeds for Persian Shield offered in any catalogues.

You can only get the plants. Sometimes garden centers if they have tropical houseplants you can buy the plants.
