    article Roses Immune, or Nearly So to Blackspot", by Chester D. Wedrick, Simcoe, Ontario
    American Rose Magazine, August 1953, p.19

    "One rose that should not be overlooked is Karl Forster, the result of a cross of Frau Karl Druschki and R. spinossisima altica simplex. It is a fair sized shrub bearing large, snow-white, camellia-like blooms throughout the whole season and seems free of all disease. Last but not least, it can withstand a temperature as low as 25 below zero successfully, without protection."

    That would be 25 degrees F.

    Thanks Nastarana. I've changed the zone from 6a to 4b. Is that OK? (I am not very good with zones.)

    Karl Forster may get a little black spot but he just ignores it and keeps flowering and growing. He has enough vigour so that the black spot doesn't effect him. However in some areas (mine for one) he doesn't get any disease.

    how much does Karl bloom for you? chris in ct.
    Reply #3 posted 21 JUL 09 by The Old Rosarian
    I get one good flush and then only a few scattered afterwards. I wouldn't call him a good bloomer in the PNW.

    Yes you do get the delicate foliage. In my garden it is a little darker green than my other Spinosissimas.

    Please note we do list the name as 'Karl Foerster' but it is also sold under the name 'Karl Förster' so we include that synonym. Thank you for the reference.

    o.K. - but it is still there: "Registration name: Karl Förster" and this is definitely wrong! LG Rsenfee

    The correct name is 'Karl Foerster', but the rose is registered in the ARS databank as 'Karl Förster'. We cannot modify this registration.
