    Soak and Start Early

    It took me two tries growing these to finally get to flowers, and they flowered late. But they are stunning and I will grow them again. This time I will start indoors very early, like, right after New Years.

    I am always impressed with their seed selection. I am also pleasantly surprised to find a high count of seeds in many of the seed packets as well. I will definitely be ordering more seeds in the near future.
