    Seedlings! What are the parents?

    Where do you live? Has it been cool and wet? That's a prime habitat for Stangonspora curtisii. I've copied and pasted a post I made in another thread regarding the dreaded "red blotch".

    I'm not 100% sure your plant has S. curtisii, it looks like it may be sun damage, possibly. Is it apparent on other leaves? It doesn't look so red, at least on my screen. If not, I would just maybe snip the leaf, don't allow it to touch the others just in case.

    Mechanical damage to Hippeastrum also cause red spots, is it possible the leaf was damaged?


    "Stangonspora curtisii is more prevalent in cooling weather with too
    much moisture. I notice it starts really appearing during fall or early
    spring when the cooler night time temperatures reach dew point causing
    plants to remain moist, although it can appear at any time.

    First, I would suggest removing your plants from conditions such as
    those, where the plants remain moist during cool periods. Your plants
    need to dry thoroughly.

    Some in moderate infections will just use a fungicide, I have seen
    both copper and sulfur based fungicides recommended. I know you can find
    sulfur fungicides in powder form that you can sprinkle the plant with,
    there are also sprays that I think work well, too. I would probably
    recommend a spray unless you're treating a small area of the plant.

    In really bad infections, I've seen some recommend removing the
    affected parts of the plant followed by a dipping in a bleach or
    hydrogen peroxide solution and then further treating with a fungicide
    application. Here is a link that can give you some more information if
    you're interested

    JoshY,

    The seed pod came from a plant with large double flowers....mostly white with pink stripes, ?...however, this plant is outdoors and there is a black pearl hippeastrum in a neighbors' garden like a block away, and they were blooming at the same time. i live in Aguascalientes, Mexico, the weather here has been nice, stil warm.....I have to read what you posted, THANKS!

    Hi Rosina, Are you sure that your seeds came from a double flower? Most always double flowers don't have female parts and are only used for their pollen, when they have it. If your seeds are from a double flower then it is very rare. It doesn't really matter though, I was just curious but as for the Black Pearl a block away in the neighbor's garden I doubt that it was the pollen donor so if there aren't any other hippeastrums around then it must have been a self. I am puzzled but good luck growing them on.☺☺☺ Donna

    Dondeldux,

    is it rare for doubles to self pollinate? Wow! I still have to learn many things about these plants ....let's see next spring.... I'd take a picture of my friends plant so we can identify it........I have 88 seedlings, 2 do not like direct sunlight and 2 have those red spots. Most of the plants have dark green leaves, a very few are light green, some have pink stripes underneath, others have bright red or dark red, almost auvergne stains underneath their leaves.....I wonder if it has something to do with the color of their flowers.

    Very interesting. Would it be possible to see some photos of the leaf variations? With 88 seedlings you should have some lovely variations, can't wait to see some of them.!

    Would someone else confirm or disaffirm my comment of doubles producing seeds for Rosina?☺☺☺Donna

    Rosina, Thanks for taking the time to post all those pictures!! I can see the red stripes on the backs of some, I am intrigued. Your seedlings look healthy and I just know they are loving that big window!! If it were me, at this point I think I would just cut off any affected leaves, move them a distance from the rest and wait to see what happens. If in the end you do loose a few it really won't matter as you have so many; but I know all your bulb children are precious...☺☺☺Donna

    Aren´t they beautiful !! I think they are happy, they are growing really fast. Thanks Donna....... I saw the black pearl this morning i went running...it has dark red stains at the bottom, underneath each leaf.

    It's a characteristic of a few of the more common hybrids.
