Re: Dianthus knappii

Just a couple of comments. In his book  on perennial garden plants
Graham Stuart Thomas says that this dianthus is inclined to be
monocarpic or biennial. I haven't paid too much attention to mine, but
it has kept itself in the garden by self seeding.
Marge makes a valid point that it will probably be in bloom after the
blue-eyed grass has finished. I have been trying to think of something
else in pale yellow that might bloom at the same time, depending on the
local climate. What about some of the smaller iris? There are cultivars
in pale yellow or cream.
I have a very pale achillea, "Anthea", but again, I don't know if it
would be in bloom soon enough. It's one of the smaller achilleas so it
would be in scale. Pansies or violas maybe?
Or would a late, pale yellow daffodil make the grade? It just might in
our climate, where spring comes late, but maybe not in yours.

Nice bright yellows I have in abundance. Cream or pale yellow is exactly what I
am looking for. How tall did it get for you, do you recall?

Does anyone else in this part of the world grow this plant successfully?

Bobbi,
   Only managed to keep my dianthus knappii for about a year, then killed
it off.
