Plant Identification

I've had this cute little clumping grass forever... bought from a vendor of alpines many years ago. It gets to 8" max in flower, and about the same around - a useful and rather attractive grass (IMO), small enough for the rock garden. It just occurred to me today, as I was photographing it, that I think it's a Luzula, from the hairy leaves and appearance of the flowers. Does anyone know which species it might be, or if not a Luzula, what it is? Many thanks in advance for clues to an old mystery.

Which Arisaema species is this? Note the red margin around the leaf.

This is what the stem looks like:

The "iris tectorum" plants I grew from seed in 2008 finally bloomed - and I don't think they are what they were advertised to be (seed from a different society exchange). They look more like the Siberian irises in our garden than online photos I consulted of I. tectorum. Any other opinions?
Thanks,
Rob

A while back I posted a picture of what I thought was a basal rosette of Calandrinia grandiflorus. Seems now, with all those buds waiting to spring open all down the stems (which are about a foot and a half tall and need "propping"}from those lovely big glaucus leaves, it looks more like Penstemon grandiflorus. The garden is full of surprises, eh? Fran

A forumist on a Norwegian forum has asked whether anybody can identify these plants from Arizona. Pictures taken by his granddad 100 years ago:

Thanks, Mark. Here is another query - probably Dave in New Zealand can help with this. Last year I ordered Hebe epacredea from the seedex. This tiny plant germinated but didn't look like pictures I've seen of this "whipcord" hebe and I thought perhaps it hadn't been named correctly. However, now that it is up (only a couple of inches high), it has developed that "ropey" look of the whipcord and I'm wondering if this is its natural development. It sure looks like a whipcord now.

Hello, This Penstemon was a seed exchange selection labeled Penstemon rupicola, which I don't think it is. Can anyone identify it? I also have a white one from the same seed packet.

Does this look familiar to anyone? This plant came up in 3 pots (two labelled as Saxifraga spruneri which it clearly isn't), which may suggest it was something in the soil I reused from last year... or that I'm really messy at planting seeds! (Yikes, was I closing my eyes and just tossing them in the general direction of the pots? :rolleyes:)

Erythronium elegans (?), both plants grown from the same lot of old wild-collected seed:
Yellow markings at base of petals:

No yellow markings:

Note that the foliage is a uniform dark green and has wavy edges, which is what E. elegans should have.

I purchased these as Gentiana angustifolia. What do you think?

The flower looks like a science fiction creation:

Is there some way to get them to make more flowers? They are in full sun.
