Fall flowering Gentians

I haven't grown Gentians before but having created an ericaceous bed (my garden soil is pretty neutral) in an attempt to cure a sick Camellia I bought a few to give them a try. Here are the first two to flower:-

Gentiana 'Strathmore'
Gentiana 'Serenity'

Nice ones David! And while it's hard to improve on the gorgeous sky blue colors, the pure white one certainly ranks right up there on the desirability scale.  Are these G. farreri or sino-ornata hybrids?  For a number of years I had one named 'Drake's Strain' and it seemed happy in the garden until it was eventually crowded out... I should try them again.

The only Gentian I'm currently growing are color forms of G. clausa, our native bottle gentian... it has been showing buds for weeks but only starting to show hints of color, here is the "alba" form about 1-2 weeks away from prime.

From what I can find 'Strathmore' is one of a group called G x stevenagensis (Stevenage is a town in the county of Hertfordshire) originally raised by a Frank Barker, of that town, and it received an RHS Award of Merit in 1934. It was a cross between G sino-ornata and G veitchiorum. G 'Strathmore' was a sport from G 'Inverleith raised by Ian Christie of Christies Nursery in Scotland in 1986.

As far as G 'Serenity' is concerned, I can't find a thing about it, but if I find more I'll post it here.

I've found them easy so far Mark, although they could have done with more sun, but will I have them at this time next year!!. They need acid conditions, a lot of moisture (they've had that!), and sun to flower to their best. I have a few others in bud and I'll post them when they open.

It's the striped backs (especially) of the sino-ornata type species that I really like. 

Avery nice selection, David!

Oh my, this is how you're supposed to grow autumn blooming asiatic gentians!

Here's how bottle gentians get pollinated, the species in question is either G. clausa or G. saponaria.


Here's a second one, with sound (pretty funny given the bee's efforts), taken on a bottle gentian in Massachusetts (thus probably G. clausa).

Mark:  Those youtubes of the gentians and bees are fascinating - I have watched the bees go in and out of the flowers but didn't realize till now that they sometimes go in head first and also back in?  Can't help but love those bumble bees.  Fran

That's a great site, David!  and not just for gentians, too.

Frances, if you are referring to the first bee video Mark posted, the bumblebee went in head first both times, but the second time turned around inside the flower(!).

Another of my small collection of Fall flowering Gentians.

Gentiana x macaulayi. I have an old book, "Gentians In The Garden", by G H Berry published 1951 by Faber and Faber (cost me 50p a couple of months ago) which, given it's age is very good indeed. Berry says that Mr Macaulay made the original cross between G sino-ornata and G farreri but it is not known which was the seed parent.
