Does anybody know what happened to my Oenothera speciosa 'Siskiyou' ??http://davesgarden.com/guides/pf/go/54831/
Last evening I noticed an entire patch of this stuff had turned brown. This morning I reached in with my pruning shears intending to cut these off at the ground with the hopes that they would return. I was expecting dry brittle plants and instead grabbed hold of slime!! Yuck! I cleaned my pruning shears with bleach and am wondering if I need to pull all these out and treat the soil. None of my other kinds of plants are affected - some right next to these. There are even some iris mixed right in that are fine so far.
added info: We just had the remnants of hurricane Dolly come through and received about 3-4 inches of rain over a couple of days and in the weeks just prior to that received another couple of inches of rain.
