Halenia species

[Moderator note: Split from "Not Gentiana but Gentianella" thread.]

I do like G amarella too :) it often grows in similar places or even with another Gentian relative, Halenia- even more subtle in flower, but also an interesting and charming plant. I think the Gentianella includes more open places in its range than does the Halenia, they overlap in woodland edge/clearing kinds of habitat; Both grow naturally on my 6 acres, but not always in convenient spots,. so I hope to get some nice patches established once I have the right beds ready..

Here's one view of Halenia deflexa, I'll find more later- I don't suppose this is an important enough genus to bother with a new thread?

Maybe we could change the thread's name to Gentianella and relatives?

Halenia is a nice one! We have nothing like it here but I observed some when I visited Ecuador 12 years ago. At that time I only used slides though.

The Ecuadorian species looks interesting- sometime when my internet connection is better I will have to study it a bit more- I'm curious how big those flowers are?
H deflexa is, again, a plant I like, but definitely in the category of 'don't let the macro photo mislead you'- those flowers are tiny (plants, as with Gentianella, can be a few inches to at least a foot) and not at all conspicuous in nature..

Hey- we got a thread! ;) guess I really have to find more photos now ;) Since a moderator must be watching- did you ever get a chance to add an Ericaceae family board for the the Arctous/Arctostaphylos hread I made in the general section under family/genus?

That's beyond my moderator super-powers, Cohan, but I'll ask Mark to do it.  :)

Edit:  Oh, I guess they did give me the keys to the place!!  :o   Viola!  There is now a board for Ericaceae.

Here's a nice blue Halenia from China:

This is a new one for me.
What are their cultural needs? Perennial or annual? Tropical versus Temperate? Were halenia once included with swertia?
I see there are only two species listed as native to the United States.

I don't know much about them, gentian relatives, with some species included in Swertia.  The bulk of the species are South American. Two species (and a couple varieties) occur in China, one with sizable blue flowers, the blooms doing a good imitation of Epimedium blooms:

Halenia elliptica, there is also a var. grandiflora with flowers nearly twice as large.

These can be both annuals and perennials.  As with Swertia, they prefer moistu locations, often found along streams and in moist meadows.

Wow! that almost looks like an Aquilegia!
The other Chinese species look pretty nice too!

John, our native species is a woodland/woodland edge species, growing from deep shade to clearings etc; I haven't thought that much about habitat before, but I think they don't grow in fully exposed places- though I know for sure the Gentianella amarella they often grow with does also grow in open grassy places, so I wont say for sure not... likewise I think their spots are not really dry though any of our wooded areas (outside actual  wet places) can be dry for part of the season depending on the year..

Not a great shot, but it shows a somewhat moist and quite shady forest habitat common but not exclusive for H deflexa; these plants are at the small end of the range of flowering size, just a few inches..

For the sharp eyed, leaves of Linnaea, Mitella nuda and a Vaccinium sp can be seen also
