Black Prince Snapdragon

Early in the season, the foliage is what stands out, being dark green with a reddish maroon overlay. When it flowers, the blooms are stunning--a dark velvety crimson, one of the richest, warmest colors I've seen. Relatively tall 16-18" and large-flowered, Black Prince is easy to grow and simply astounding with other intense colors like silene or lobelia.

    Absolutely love the color of these!

    The photo does not look as dark maroon as the flowers I have. They are really stunning and draw a lot of attention in an arrangement due to their deep dark color. The stems are pretty narrow and they are not real tall, but the color makes up for all of that!


    Slow to start but getting gorgeous in zone 3-4!

    You'll definitely want to start these indoors as early as possible if you live in the far north, but it's August now and they are really coming into their own! The color is amazing - richer and deeper than on my computer screen! I have a moist area that almost never dries out and they seem to like it there. They make long-lasting cut flowers as well. I hope they last well into fall. They aren't showing any signs of stopping.

    No Mildew here

    Aside from the gorgeous foliage and stunning bloom, this heirloom is completely mildew free in our zone 9 garden . It performs earlier and through the main snap season and then continues on past all its contemporaries being the last to succumb to our blazing summers. With a quick cut back, it takes the summer siesta and then does a little dance again for fall. What a Prince!
