Over the years my mother has collected numerous plants and even kept them in her decor throughout the whole year. I think it's because she puts them here and there while she's decorating for the holidays. Then she forgets all the ones she has placed in every room and along her way to moving them, finds more to use in decorating. It's not uncommon to find one sticking out from a fake plant of other sorts or alone in a vase in a bathroom.
This morning I found a box full of fully bloomed poinsettias in her Christmas storage closet and picked one out to send over to her. Maddie was going to place a few outside but I got worried they would weather in the snow and be ruined (though they are fake and some show years of sun damage).
I think it's the familiarity, the vibrant color that is so alluring. I only wish I had chosen a white one, which is supposed to symbolize the star of Bethlehem rather than the red one, which is the crucifixion.
