These plants are in my garden, grown from seed saved each year originally from Nasami Farm where I talked Bill Cullina into sharing some seedlings with a propagation workshop. I have seen them in Western Massachusetts at the Williamstown preserve growing in a calcareous seep

That's very nice, Peachy. How tall does it get?
Does Gentianopsis critina - which is gorgeous indeed! - need a lot of water, in your experience?

The A. uncinatum, native to southeast US grows about six feet and requires other plants for support-as shown it is growing under a large Walnut tree and is leaning on some native hydrangea. G. crinita seems to do well in average garden soil, in my case neutral to mildly alkaline, with good water holding capacity, no extra watering required, it is, of course, biennial.
