We grow blue flag in our pond, in a LARGE pot. The foliage emerges by early spring, which is great at a time that most pond plants still play dead. Then we just wait until the display of deep blue flowers starts, usually by mid-May.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

|Anne||Oct 06, 2010||USDA Zone 2, mid June to mid Aug can see temps. into 100F with high humidity, growing in CLAY SOIL that has been amended with sawdust & shavings, and a small amount of Peat Moss. They were put in a holding bed 2 years ago, high and dry - watered maybe once a week. No winter protection given - bloomed prolifically and have increased size by about 3 times. Gotta love this plant - no bugs or disease - foliage stays green all summer.|
