I found this on IWGS this morning :'(
Texas Bans Aquatic Plants—Will Pond Fish Follow?
9-13-10
Greetings, Water Gardeners--
This letter is to alert you to a huge concern we have over new legislation regulating aquatic plants in Texas.
You may not think this issue concerns those of you in other states, but you are wrong—state legislators are famous for copying the new laws from other states and passing it in their own states. Even if the original state performs due diligence and shows restraint in what plants it restricts (an optimistic perspective indeed!), the “copy and paste” techniques of other states seldom take into consideration the differences in their climate, geography, economy, etc.
And you will be interested to learn that Texas officials have expressed the intent to do the same thing with pond fish at some point (how enthusiastic they are may depend on how successful they are with aquatic plants). State by state, we will be increasingly limited in what we can grow, sell, and keep in water gardens. The bias of a number of organizations to use only locally native species will limit the aesthetic and ornamental value of water gardens.
We need as many hobbyists and water gardening businesses as possible to voice their concern and displeasure at the thought of losing many of their favorite aquatic plants.
Please visit the IWGS (International Waterlily and Water Gardening Society) website for the latest updates on the Texas White List:
www.iwgs.org . The Texas White List is a list of all permissible aquatic plants in Texas. All plants must undergo a rigorous process before being allowed on the list. No new plants will be allowed before undergoing this process, and any aquatic plant not on the white list will be prohibited.
At this moment the fate of waterlilies in Texas, other than the species native to Texas, is uncertain at this time. Texas is still conducting risk assessments on both hardy and tropical waterlily species and their hybrids.
We have just learned that the Asian lotus (Nelumbo nucifera) and therefore all lotus hybrids have been taken off the White List and will be illegal in Texas as of January 1, 2011. This will include using lotus tubers for food.
Along with Asian lotus, the following aquatic plants are among those that failed to be approved and will be banned:
Imperial taro and Lime Green taro (Colocasia antiquorum and C. Elena)
Umbrella Palm (Cyperus alternifolius) – often used as a house plant or as a terrestrial
Mexican, Egyptian and Dwarf papyrus (Cyperus giganteus, C. papyrus, and C. haspans)
Butterfly Ginger (Hedychium coronarium) – terrestrial!
Chameleon Plant (Houttuynia cordata) – terrestrial!
Creeping Jenny (Lysimachia nummularia) – terrestrial!
Dwarf Cattail (Typha minima)
Narrow Leaf Cattail (Typha angustifolia)
Graceful Cattail (Typha laxmannii)
Wedelia trilobata (creeping oxeye, yellow dots) – terrestrial!
Water Poppy (Hydrocleys Nymphoides)
Variegated Water Snowflake (Nymphoides cristata)
Yellow Water Snowflake (Nymphoides geminata)
Mosaic Plant (Ludwigia sedioides)
Water Mint (Mentha aquatica)
