    A very attractive and sterile ornamental basil that produces a profusion of lovely, purple tinged leaves and continuous large spires of blooms all season long. The flowers are beloved of pollinating insects of all kinds. It is such a joy to see so many native bees working this plant!

    'African Blue' is my favorite ornamental basil. I have grown it two seasons in a row now, and I intend to grow it next year as well. It grows in full sun to a good 3 feet high, bearing tall stalks of pink flowers against purple-veined leaves. 'African Blue' is a cross between Ocimum kilimandscharicum and Ocimum basilicum 'Dark Opal'. The pollinators love it. Its high camphor content (inherited from its East African parent, Ocimum kilimandscharicum, or camphor basil) makes it a less desirable culinary herb, but it is beautiful as an ornamental pollinator magnet.

    This plant has performed exceptionally well for me. Which is no easy feat for any plant in my garden this year. I had mass casualties from squirrels, gophers, and spider mites. Yet my African Blue Basil looks perfect. It is a blooming machine and always looks healthy. The bees are very fond of it, which is great. I highly recommended this plant!

    This is my favorite basil. Its flavor is a bit more mellow than sweet basil. I find it blends well with sweet basil when I make pesto, it provides a bit more depth. It's also a beautiful plant.
