okay - yesterday i added black color-enhanced mulch that was in my garage for about two months to a group of pansies i planted in early may. this morning, there were two pink finger like things growing out of the mulch that were about six inches long and about an inch thick. i thought they were snakes. being new to the "country" i waited for my husband to get up and went out with him (about 1 hour later). they were already shriveled up and looked dead and were definitely some kind of plant. any explanation?????
