Not really blue, but closer to blue than most other pinks. Lots of fringed blooms from early to mid summer over a clump of loose dark green narrow foliage. We like to tuck it into tight corners here and there, and now also feature it in the rock garden. Botanist have apparently shoved D. amurensis in with D. chinensis, but to me it's a sufficiently distinct plant that I'm maintaining it under its old name, separate from the shorter-living D. chinensis (usually grown as an annual around here).

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston. Seed for this plant is included on my seed trade list One or more images of this plant are included in my stock photo catalog About my plant portraits

I thought you might be interested, re Dianthus 'Siberian Blue', in an English plant company Thompson & Morgan (www.thompson-morgan.com). They are selling 84 plug plants of the above for the bargain price of £10.95 plus £3.99 p+p (probably only within the UK though).
Thanks to your photographs & recommendation, I shall be trying these out in my dry chalky soil here in Brighton, on the sunny south coast of England, where hopefully they will last for many years.
Thanks everso, ta-ta.
Sounds like a good bargain - thanks for sharing :-) They're not difficult to start from seed, either. |
| Vera | Jun 30, 2009 | Flowers first year from seed if wintersown as well.
Not anywhere near close to blue that I can tell, but I love the dusky muted pink anyways! It blooms later than most Dianthus that I'm familiar with here in my garden. |
| Barb | Nov 30, 2010 | Very long season of bloom, very good colour. Great Dianthus in general, but sadly not fragrant - its only drawback in my opinion! |
| ellen | Mar 03, 2011 | I grew this Dianthus from seeds that someone had given me. (also Wintersown - very easy to germinate). I gave two of the sporuted ones away because normally I don't like dianthus. When I saw this one, it took my breath away. Almost phosphorescent in color. Now I must have more. |
| chris | May 08, 2011 | I started some Amur pinks from seed this spring, but have never seen the plant actually growing (that I know of). For where I want to plant my seedlings, I need so ething that will be evergreen. Is Amur dianthus evergreen in Zone 6?
If I recall, it holds its leaves through the winter - but like most dianthus, it doesn't look its best until the leaves refresh in mid-spring. |
| Sheila | Aug 01, 2013 | Can the soil pH be adjusted to shift the bloom color more toward the blue end of the spectrum? My Siberian Blue is an ugly fuchsia. Very disappointing.
I don't believe that dianthus responds to soil pH the way hydrangeas do. Soil composition may have some effect on flower color, but you may simply have a strain that blooms in that particular shade. |
| leeneia | Apr 13, 2020 | I love Siberian dianthus. I live in Missouri, and I have seen temperatures range from -20 F to 110 over the years. In 2010, when we had an unusually hot, dry summer, my "Siberian" dianthus bloomed unfazed. The plant never seems to have a mix of live and half-dead blooms, the way some other dianthus does. |
