I’m not 100% sure if this is perennial honesty or the transitory kind, but I’d guess the former. Giveaways would include the seed heads which are pointed ovals rather than the classic coin shape, and the lower leaves which are heart shaped.
The colour makes me think it is Lunaria rediviva, and it does look well established here, but I stand to be corrected. If you know better, please leave a comment and I’ll put things right.
My main reason for posting is to celebrate their freshness – luckily, we don’t need to be experts to do that!
The cluster is rather airier than it appears when looking down. Individual flowers have a simple, pleasing shape that could hardly be improved upon. I have never seen a double form of lunaria, although there are variegated forms.

Our blooms are are deep purple – I’m not sure what that makes them
It makes them very attractive, I imagine! I have spotted some deep purple comfrey plants on my regular walk, but they are growing on the side of a drainage ditch. I am not sure if I want to venture down to get a picture… certainly not worth trying on a windy day!
I’ve never seen this plant before – it’s beautiful! Will it have the same sort of seed heads as the purple flowered lunaria?
The seed heads have the same papery nature, but they have tapered points.
I shall look out for one!
I have never seen this plant before, either. Absolutely lovely!
Do you have the other kind of lunaria over there? Some people call it money plant – it is the papery seed heads that are most memorable.
Yes, we do. So pretty.
If there are only two choices, I would go with the former, just because it does not look like the latter.
It’s the same plant, seen from the side and overhead. The overhead picture is a bit misleading as the plant is airy. You might like the pure white form, though it’s biennial.
I mean in regard to the first paragraph. I would guess that this honesty is the formerly mentioned perennial sort because it does not look like the latterly mentioned transitory type.
The honesty that is almost naturalized here is the common sort. We collect the seed to disperse where we think it will do well because we do not want it to eventually go extinct. (It is a tradition here.) Someone else mentioned that the white sort is true to type! I therefore might add some, although I do not know how it will mix with what is already here. I do not want it all to be white. If I add white, the dispersion of its seed later on will be confined to specific regions. I could not prevent it from spreading, and would not care to, as long as it never completely replaces what is already here.
Oh, I see what you mean. The white never seems to predominate here. Mixing it in will change the effect. I always like to see violets of different colours mixed together.
I do not mean to take up your time, but I have a quick question. If white gets added to what is here, will their progeny be either the original color OR white, or will the color range from the original to white, with everything in between? If it will compromise the original color, I will just put the white in my own garden, where there are none of the original anyway.
I am not sure whether you will get intermediary colours, but I’ll observe more closely the next times I see some patches of mixed pink and white. I have certainly never seen a pale pink biennial honesty.
There is no need to go out of your way. I lack seed for white anyway, and if I ever get any, would just keep them in separate garden until I know they can be mixed. It could show up on its own, as so many of these wildflowers occasionally put out an odd color. I have been wanting a white perennial pea for years, but the seed from the white ones are not white.
