Marketing the Texas Prairie Dawn

Hey Boss,

As requested, I have gathered all the information on the Texas Prairie Dawn.  Originally I thought that we might have been able to capitalize on this species, but I think we should take a step back and reassess its potential.  The following outlines its classification:

  • Kingdom – Plantae
  • Phylum – Anthophyta
  • Class – Dicotyledoneae
  • Order – Asterales
  • Family – Asteraceae
  • Genus – Hymenoxys

The main problem I have come across while researching the Hymenoxys texana, is the fact that it does not have many adaptations that increase its chance of survival.  However lets take a look at the following three:

  • The Texas Prairie Dawn can grow in lightly vegetated areas.  In fact it can grow in areas that others plants won’t, due to the lack of neutral water or improper amount of nutrients in the soil.  Unfortunately, it doesn’t thrive in areas that are highly vegetated, because it does not grow as fiercely as other plants.
  • It can grow in coastal areas, where we find salty and or sandy growing conditions.  The soil does not need to be as packed or as concentrated.
  • It can grow in soils that contain moderate alkaline levels.  To other plants even small amounts of alkaline levels are hazardous to their survival.

The Prairie Dawn is a member of the sunflower family, even though they only reach a height of about six to seven inches.  I would speculate that we could get the best use out of this plant by capitalizing on its ability to vegetate in salty, alkaline enriched soils.  By using specialized breeding methods, we could crossbreed it with a regular sunflower and perhaps create new species that would grow in different environments around the globe.  To do this many things would have to be researched, including, but not limited to: how exactly the Texas Prairie seeds, how a regular sunflower seeds, if the two are crossbreedable, the exact types of soils we should market too, and of course what kind of markets we would be shooting for.

Due to reproductive isolation, chances are likely that even though Texana and regular sunflowers come from the same family they cannot reproduce.  There would have to be a lot of research committed to the understanding of a possibility in fertile offspring.  The overall outcome would be to create a species of sunflower which produce sunflower seeds that are edible to humans in areas that were once to salty or dry.  To do this we would need to breed the Hymenoxys texana with sunflowers.  Those offspring would be grown in salty alkaline environments.  The offspring, which were able to grow and reproduce, would further be bread with other sunflowers and planted in perhaps increased salty or alkaline environments.  Inevitably the outcome would be a sunflower plant capable of producing edible seeds that could grow in different soils.  We could catalog and organize every plant to determine which offspring grew best in which condition.  After about 2 years of breeding we would most likely end up with 20 or 30 soil adaptable plants.

The end product could be most profitable.  We could analyze the soil type and recommend a specific plant based on two years of selection and reproduction.  Ethically this is a great plan.  Not only do we provide a larger food selection to areas that once was not able to sustain it, but we also create a species of the Hymenoxys texana that could survive and reproduce better.

Texas Prairie Dawn

  HYMENOXYS TEXANA












(Picture Take by Larry Allain USDA)

The Texas Prairie Dawn is an endangered flower found here in Texas only.  If you live in Harris County you may have even encountered it.


It first showed up on the endangered list in the early months of 1985.
Although this flower is commonly known as Texas Prairie Dawn, its scientific name is Hymenoxys texana.
The Classification for the Hymenoxys texana is as follows:
*Kingdom - Plantae or Plant 
  *Subkingdom - Tracheobionta
    *Superdivision - Spermatophyta
      *Division - Magnoliophyta
        *Class - Magnoliopsida
          *Sublcass - Asteridae
            *Order - Asterales
              *Family - Asteraceae
                *Genus - Hymenoxys Cass.
(Order provided by the US Dept. of Agriculture)

The Prairie Dawn is Eukaryotic, meaning its microscopic cells consists of a highly complex structure surrounded by a protective membrane.  It is multicellular with millions of microscopic cells making up even the tinniest part.  It would take 10 to 100 times amplification to even make out one of them under a microscope.  Since the Prairie dawn is a plant it is stationary and immobile.  Also because it is a plant, it uses photosynthesis to make its own food.

The Prairie Dawn is a flowering plant.  This means that it does seed.  In fact the plant seeds between April and May.  The seeds for this particular plant have been described by the Center For Plant Conservation as "cone-shaped and hairy."

The habitat of the Prairie Dawn is actually right here in our own back yard, in and around, Harris county.  The seedlings grow the best in open fields and grassland in specific types of soil and soil composition.  That type of composition is defined by its salinity and acidity.  It grows the best in sand like soil that receives ample amounts of hydration.

Unfortunately urbanization has not only been beating at the doors of this plant, but thanks to altering water flow and drainage a once sustainable water table has been heavily fluctuating causing the soil conditions to be unsustainable to the Prairie Dawn.  This topic will be addressed later at the end.

The Prairie Dawn does not have any features that would make it useful to modern day bioprospectors.  The only reason this plant has not been wiped out by construction and development is because it was placed on the endangered species list.  If it did have any special features I would assume that they could also be found in their taller more prominent "brother" the sunflower.

The Prairie Dawn's biggest threat is not global warming, its people.  Global warming might actually help this plant because it would make humans more understanding to the needs of our environment.  Unfortunately, right now, the protection of rear species is not always at the top of our societal lists.

Lastly, I would like to mention that this plant's status is endangered.  It was actually speculated that the plant was extinct in 1979, until it was found again by James Kessler in 1983.  Since than efforts have been made by groups to protect this particular species from extinction.  It is sad to think that the Prairie Dawn might have been extinct due to our constructional needs and land developing movements, if it wasn't for a select few groups working to preserve it.
