    Hi Fdland,

    I couldn't find a picture of coral bells with rust, but here's a jack in the pulpit with it.

    Bacterial and fungal leaf spots.

    Downy mildew, powdery mildew and gray mold also attack heuchera - coral bells.* If none of the first ones look like what you have I can search more.

    [align=left]looks similiar to the *bacterial leaf spot.* The leaves are red in color so the damage looks a lot more rusty, very dry, and crisp, and covers almost entire leaf. started on a few leaves now on entire plant.* Does not look like fungi picture. thanks [/align]

    I've read that many of the new cultivars are prone to many diseases.* Sorry to hear this.
