I am very encouraged to try the spuria irises! I'm definately going to give it a go! I expect they will be short here. We are close to the mountains and at a high altitude ao we only  get about 5 months of dependably warm weather, but they are beautiful and it's worth a try!

We grow about 60 cultivars of spurias in a very open area, and don't find wind a problem. Also in our warmer climates spurias grow to full height.
I was surprised when I went to Portland last year how short the spurias were and how late they flowered. However by comparing notes with others that grew spurias in both warm and cold climates we realized the difference was the winter dormancy. In warm climates (California, Australia) the spurias go dormant in mid-late summer (if not watered) and start to make their new growth in autumn. This means they have about 5-6 months growing before flowering. Whereas in areas where they are covered in snow in winter, they have only about 3 months growth before flowering, therefore they flower shorter and later.
We find spurias to be the toughest of all the irises. They are more damp tolerant than bearded irises, and once established are very drought tolerant, but not in their first year. We have some established clumps of spurias that receive no summer watering at all, and they still grow and flower well, but not quite as big a blooms as the irrigated ones. About the only things they don't like is to be hot and wet in summer ( eg lots of damp mulch in hot weather), and a complete lack of winter cooling.
Get yourselves some rhizomes, and set and forget, they are also very happy to be left for years without being divided. They are also great for floral art

We only have a few spuria, but so far they don't seem to be bothered by wind.

Wonderful! These tolerate wind pretty well, then?

Another first year plant in our garden.  This bloom survived a morning downpour and an afternoon of wind.
