According to the label, this plant will flower in profusion from May to September, and judging by the number of blooms and buds on it at present, this sounds highly likely.
My usual technique is to grow plants like this in pots, so that I can move them around at will. For the time being it is sitting next to a pot of variegated sage, whose gold and pale green leaves set it off very well.
Here's a closer look at a flower. It reminds me of an old-fashioned pin-cushion! From a distance, the flowers appear black, but when you get close they are really a very dark purple.
While I was taking that shot, a fly decided to photo-bomb (see below, bottom left)...
For those who are interested in the details, this is a hardy perennial, which prefers a sunny position in well-drained soil, and is a good one for attracting bees. It will grow to about 20 inches tall.
Can you see the greenish flower-bud at bottom left in the photo above? That is a white-flowered Echinacea, which should look good next to the black Scabious when it matures.
