This is the first year I have ever had Dutch Iris. I planted them last fall, and I am seriously in love with them. And they last forever. All the buds opened a month ago and they still look beautiful.

So I thought to myself, "hie thee to the Dutch Iris mail order site forthwith." So with a hie and a hoe, I forthwithed. And I was deeply saddened and confused. There appears to be very little choice in Dutch Iris. Everyone offers pretty much the same fare: Mystic Beauty, Eye of the Tiger, Rosario, Blue Magic, White Magic, Telstar, Cream Beauty, and a handful of others. Can anyone point to the magical specialty source for Durch Iris?

I don't think there is much more variety than what you've seen. Dutch Iris are registered with the KAVB in the Netherlands, they have a total of around 150 covering the entire span of dutch iris registrations. Of those approx 150 I wouldn't be surprised if less than a third are still grown for sale anywhere in the world.

Australia has basically the same small selection, just slightly different cultivars (ie Casablanca is the white form here instead of White Magic).

Of the ones you listed above though, I think the only missing colours are the full yellows, the yellow/orange/bronze (like Autumn Princess) and the "red" ( like Red Ember, which is only red in certain light).

There's just not a big market for Dutch Iris that's looking for "new" and very few breeders....it's one of the one of the plant groups that will require the hobbyists to drive it forward. Much like Alan McMurtie is doing with the reticulate iris group (and even then it's a big up hill battle)
Anyone with oryzalin (aka Surflan, Embargo), am looking for a small amount rather than 5litres from manufacturer (min size in Australia....)

Wow. How do you know so much about the history of the Dutch Iris? I love reticulata as well although I only have three: ones you see in all the catalogs.

Obviously, I am not acquainted with the iris people. I joined the iris society and also SIGNA this year, but I really do not know what that means. It is a little different with the daffodil people. But thanks. Feel free to pass on more history. I love it! Really

I tend to get an interest and then research heavily...it's all info available online.

I like dutch iris, I've considered breeding them several times but access is problematic for me. Access to chromosome doubling chemicals in Australia is difficult (unlike the USA were you can just get it online), it'll likely be required to convert a diploid to tetraploid to be able to use as pollen to have limited fertility with existing triploid cultivars. Prone to rot (hot, wet summers, they seem to want a very dry period after flowering). Access to species seed is very low (ie check the various seed exchanges for I. xiphium and I. tingitana they use to be around a bit in previous years but have declined/disappeared in recent years) so how to create a tetraploid in the first place? If something really new is wanted then breeding with other species in the xiphium group would make sense (but again access to seed or bulbs is problematic) but given differing chromsome counts means it'd need to be at the tetraploid level (see first issue) to be fertile (i.xiphium and i.tingitana have been bred with i.boissieri and i.latifolia)...so there is potential there but no market (garden or florist) is really pushing for anything new with them so they kind of stay fairly similar, many cultivars being 50+ years old and a new intro showing up infrequently from the limited breeding that does occur in the netherlands.

@Protoavis, I don't know if you can get any of the false autumn crocus. Colchicum plants are very poisonous and its poison is colchicine that causes tetraploidy.

Interesting! I'm all ears!

I have plenty of Colchicums, but I doubt they would be allowed into Australia. They have a very strict approach to plant imports.

It still kills embryos & plants, but what survives is transformed to tetraploidy.

They look stunning against the green foliage of the plant around them.

I have tried to grow them in pots - unsuccessfully - but I am determined to try them again! Crossing Fingers!

Sadly they only sell retail.. but perhaps you can ask your local plantshop to order them for you?
