Hydrolea ovata is a sweet little native that will do well as a marginal or submerged plant addition to your pond.
Hydrolea ovata is native to the United States. This endangered [1] plant is an aquatic, perennial herb
that grows wild along ponds, streams and rivers. It can also be found in low-lying, consistently wet wooded areas, such as swamps. H. ovata growingat the water's edge is frequented by minnows that use the plant for cover and also seem to enjoy darting between the plants.

H. ovata forms a rhizome and will grow approximately 2 feet tall. At first glance, this plant appears to have soft fuzzy hairs on its stems and leaves; however, these may become spiny over time and can prick your skin if mishandled. Lovely clusters of small, deep blue flowers appear from midsummer through early fall to light up the bottomlands where it grows.
Some common names for H. ovata are blue waterleaf and false fiddle leaf. It is also known as pigweed in Arkansas where it can be found growing in the bottomlands of the White River National Wildlife Refuge.
At the USDA Plants website, H. ovata is listed as having been found growing in the following regions.

The Wetland Indicator Status chart found on the USDA plants database site designates H. ovata as OBL or; "Occurs almost always (estimated probability 99%) under natural conditions in wetlands." This is true of all the states except Kentucky where the wetland indicator status is, NI or "Insufficient information was available to determine an indicator status."

I have not grown this plant in my own garden but I did admire it while living in Texas and Arkansas (where I was told by Arkansas natives that it was called pigweed) long before I knew the name of it. If you would like to grow H. ovata in your own garden, plant in full sun to dappled shade in a wet location. They are best planted in groups because the spread of the plant averages approximately 3 to 6 inches, if that. They are tall (up to 2 feet) and narrow. If you do not have a pond, creek or swamp in your back yard, create a bog garden for this and other plants that like wet feet. Mix in some yellow and white blooming plants for contrast. H. ovata will really stand out if planted in front of Canna indica. The large leaves of the Canna lily will create a great backdrop for the blooms of H. ovata.
When in bloom, throngs of butterflies, bees and birds swarm around H. ovata. It is deer-resistant, making it a good choice for rural gardens. Smaller critters such as squirrels, groundhogs, raccoons and opossums tend to give it a wide berth as well.
It should be noted that H. ovata can be invasive under the right conditions. If grown in a contained area such as a bog garden where it can be controlled, it is well worth a try, especially for those native plant lovers around the U.S.
