The colorful nature of Louisiana plants is well known to locals and tourists alike. The Garden District in New Orleans is famous for its many green spaces and the amazing plants that are cultivated there. Louisiana wouldn’t be the place beloved by so many without its iconic colors and textures.

These plants take 10 years to mature, but once they do they grow tremendous, 15′-tall spikes that grow clusters of flowers that are yellow with a tinge of green.

This plant is spectacular in flower beds and rock gardens, but it should be planted away from foot traffic because of its spikes. They require full sunlight and soil that drains well and is gravelly or sandy.

Cream wild indigo is a plant that grows up to 24″ to 30″ tall and blooms with showy, cream-colored flowers in the late spring and early summer. The blooms stay on for about three weeks, attracting butterflies and bees to their interesting, pea-shaped flowers.

When the leaves are gone in the winter, the seed pods often remain, making this an all-year plant that will keep looking interesting even during the colder months.

You can use the dried seed pods in dried-flower arrangements.

6. Watershield (Brasenia schreberi)

Brasenia schreberi

Watershield is a lovely plant that grows leaves that lay flat on the water. Looking like tiny lily pads, these plants grow to be just 2″ tall on small stalks that stay attached to the middle of each leaf.

It grows burgundy or purple flowers that bloom in the later summer into the early fall. Its flowers are about 1″ across and each blooms for two days. They release pollen and are pulled under the water after two days, and they grow their fruit there.

Found wild in a number of bodies of water, it grows best in full sun and in muddy, shallow areas of water that are about 8″ to 10″ deep. Perfect for ponds and lakes, they provide food for waterfowl and protection for fish. 

7. Tall Thistle (Cirsium altissimum)

Cirsium altissimum

Tall thistle grows to be very tall- up to 7′ in height. As a native thistle, it isn’t hard to control or invasive like many other types of thistles can be. It has branched stems that from mid-summer through fall will grow flower heads that are pink or purple and that look like pincushions and measure about 2″ across.

From these pincushions come a bushy, bluish-purple flower that lasts about six weeks. After that time, the flowers are replaced by cottony hairs that are easily blown around in the wind. After this flowering, the plant will die, but tall thistles do self-seed.

Plant them in either light shade or full sunlight in moist soil that drains well.
