I remember hearing about Blue Gentians when we were in Switzerland way back in 1974. I don't recall seeing any of them, but apparently they were legendary there, just like the Edelweiss. Now fast forward 34 years, where I was found wandering around on a day in May at one of my favorite garden centers - Beining Nursery. Looking up and down the rows of perennials, Gentiana dahurica jumped right out at me.
It wasn't blooming, so I consulted the tag:
One of the easiest gentians to grow, this species is a great addition to rock gardens! The deep blue, 1”, bell-shaped flowers bloom in mid- to late summer. The lance-shaped leaves form a basal rosette. Plants like cool weather, full sun, and good drainage. The basal foliage can grow up to 6” tall, while in bloom the plant will reach 12” tall. Zone 4.
The picture on the tag shows a brilliantly blue flower. I love blue flowers. So I took the last two pots and just like that, I've got Blue Gentian. It's probably not the Swiss one, but there are several varieties, even over there, so who knows. A few weeks ago, it started blooming and ohhhhhhh, that BLUE!
I don't know if I can put into words or even if any picture I post here can adequately represent the hue of blue that my Gentian wears. I'd advise that you get one (or three) of your own, then you'll see what I mean!
