FOR IMMEDIATE RELEASE
February 17, 2005
Lots of rain, however, is not always good news for all wildflowers, especially Texas bluebonnets (Lupinus texensis). Excessive amounts of rain and persistent damp conditions can make young bluebonnet seedlings sensitive to fungal infections.
"In late November we received several calls reporting bluebonnet seedlings that had suddenly died off," said Mark Simmons, Wildflower Center ecologist. "We want to better understand the conditions in which bluebonnets are prone to infection, so we sent several infected samples to Texas A & M for study."
A fungus that causes root rot (Phytophthora) was found to be the culprit. Root rot fungus can infect healthy seedlings if they get too much water and are not planted in well-drained soil.
"We don't think the problem is widespread, but there could be some areas where bluebonnet displays may suffer," said Simmons. Additional studies must be done to determine the extent and impact this fungus will have on Central Texas bluebonnet crops.
Many of the other wildflower species are not as sensitive to fungal infections. Wildflower enthusiasts can expect to see plenty of Indian blanket and Black-eyed Susan blooms this year.
At the Wildflower Center, visitors can enjoy six different photo opportunity spots throughout the grounds. These areas allow visitors to capture a wonderful photo next to a bluebonnet display without trampling the flowers for the next visitor.
As the bluebonnets and Indian paintbrush begin to fade, the region will experience other blooms and colors. Many of these flowers overlap from one month to another.
