I always pass on these bulbs at planting time because they are often a bit on the pricey side, but then I see them blooming come spring and wonder why I was so cheap. And they naturalize easily, too.
The other day, while taking this photograph, I realized I had never smelled the flowers. So I did. As you can imagine they bear the subtle scent of black currants.
If you get a chance, I suggest you try it.
