I would like to obtain a hardy wallflower in a soft yellow.
Ordered a Scented Gold which is Erysimum perovskianum,
but it is recommended as an annual?
I would want to be able to buy seeds for them.
Anyone know anything about Afghan wallflowers, and /or Erysimum Alpina?
The names on wallflowers confuse me, as I think there are several names for the same plants?

Hi Caroline! Have you looked at Wrightman Alpines on-line catalogue? I bought a dwarf, hybrid wallflower from Wrightman Alpines in 2004, planted it in my gravel garden, and it lived and flowered for 6 years. It was Erysimum 'Turkish Delight'. I just checked Harvey Wrightman's current plant list, and he isn't offering 'Turkish Delight' any more, but he does list two alpine Erysimum species with yellow flowers.

Thanks June!
I will check there.

I think the one that I need is called Swiss wallflower.
Anyone know who carries seeds?

I have not found Swiss wallflower seeds or plants.
But I have found a candidate in my own back yard almost.

Erysimum arenicola also called Erysimum torulosum?
Cascade wallflower after the mountains in Washington and B.C.

Found seeds at Plant World Seeds in UK.

This may be a hardy yellow wallflower.

I tried Erysimum Perskovskii but it is too weedy looking.

cute!

here is the one we have in my neck of the woods

Have you seen this one?
http://www.bloomingnursery.com...
it says zone 6 here on this site, but the one I bought locally was labeled as zone 4.
It has done fine, except for the year I let it get smothered by other plants...

I've not tried that one, but E. capitatum has been in my garden for several years. I grew E. kotchyanum in pots, and they bloomed in the pot before I could get them planted out in the second year.

Thank you for the information on hardy yellow wallflowers.
I shall research those also.

I am looking for a compact alpine plant.
The kotchyanum may be that?

The capitatum , like the perovskianum, would be better in a wild flower meadow.

Sometimes it's hard to know how a plant might grow in the ground, as opposed to a pot. I have had different things grow shorter in the ground and taller, depending. But I have flowered E. capitatum in a pot, too, and it was definitely taller in a pot than E. kotchyanum in a pot.

And pinching maybe would keep the weedy ones more compact?
I seldom think to do that with outdoor plants.

I guess so. Not sure how well it might flower though: just multiple small heads? And how many?
When I grew them, they certainly weren't vigorous like a garden chrysanthemum or coleus that respond well to pinching.

I obtained seeds for Erysimum tortulosum (also called Erysimum arenicola), but I had to quiz the supplier because the seeds did not look like the usual Erysimum seeds which are tiny grains. These seeds looked more like lily seeds.
The supplier assured me that I had been sent the correct seeds, and that these had wings to aid in dispersal.

I see what you mean, but they are definitely not Lilium seed. They look like Alyssoides seed. A. utriculata is a commmon imposter of Erysimum capitatum in seed exes. Nevertheless, still a plant worth growing. Dark yellow flowers over brown (sometimes almost black) sepals can be striking. Makes nice seed pods for dried bouquets. You can use the raceme of egg shaped light brown pods, or wait until they dehisce like L.unaria or Fibigia, producing little oval translucent windows:

Fibigia clypeata

I get lost in all the Erysimum names!
Now I find that the proper name is Erysimum huber-morathii ?
I also had the name as Erysimum arenicola ?
And Cascade wallflower?

And to boot----some are called mustards?
Botany is very confusing!

Let us know what what you grow Caroline

Nice Rick! always such amazing file photos at your disposal

dirtdorphins said:Nice Rick! always such amazing file photos at your disposal

Of course, all my original photo files are backed up too, but as I take pictures, there is almost always a representative photo (or 2 or more) from each group of photos of the same subject that I process for use in places like this forum. Each of these is organized into folders and renamed, but still with the original file name, and put in a separate "master" library. So from this easily searchable library, the right pic is handily available, and I can easily find more unprocessed same subject pics with the simple search function and the original file name. I never need to actually search through oodles of original photo files to find what I want. A stitch in time saves nine!

You've prompted me to see how big my processed library is and I was astounded. It really adds up over time:
more than 9000 pics in 400 folders!

Unlike the photo organizing programs that inevitably will become obsolete, I take solace that the basic folder system will always persist.

Good system ! Rick.

I have seeds for 4 or 5 different Erysimums now, and a yellow alpine mustard. Recently I learned there are 567 species of Erysimum on the planet !

Alyssoides utriculata

I will need to examine the plant obtained:-- to make sure it is Erysimum, and not the imposter !

Carolyn, I image specimens at the University of Alaska, Anchorage. Today I imaged a number of Erysimum. Never heard of them before, but they are indeed part of the mustard family. Seems like this forum is where I need to lurk. I also take care of accession into and taking pictures of the rock garden at the Alaska Botanical Garden in Anchorage. I have learned so much. I have been trying to identify a plant called Draba bryoides. Found it might be Draba uncertain ssp. bryoides. Did a bunch of Draba todays also and can see why there would be confusion in identification. Lol
