Texas Bluebonnet Alamo Fire

Lupinus texensis

5 grams (~150 seeds)

1 ounce covers 78 square feet, 35 pounds sows one acre. 

Annual

This magnificent Texas native bears fragrant maroon flowers.  It was selected from a wild blue population, and has larger flower clusters and leaves than many bluebonnets.  This hardy wildflower takes some care to seed,  requiring well drained soil, but once established it readily reseeds and makes a great choice for drought tolerant mass plantings.  Can also be grown in planters and hanging baskets.  

Plants grow to a height of 1-2 feet.  

Peak bloom is generally March through May, but varies in different environmental conditions.  

Direct sow 1/8" deep in spring or fall, or start indoors in winter.  Ideal soil temperature for germination is 55-77 degrees Fahrenheit.  Germination may take 15-75 days.  Seed scarification can lead to faster germination.


Seed Scarification
As noted, bluebonnet seeds have hard seed coats that often delay germination for a year of more. To increase the germination rate the first year, growers often scarify seeds. Scarification means scratching or nicking the seed coats to simulate natural weathering processes. Once scarified, most seeds will germinate quickly and should be watered for several weeks, especially if the weather is dry.

You can use the following methods to scarify seeds:

    * Physically nick the seeds with a knife (for small quantities).
    * Rub the seeds with sandpaper.
    * Freeze the seeds overnight, then quickly pour boiling water over the seeds and soak for several hours at room temperature.

It is not recommended to scarify Bluebonnet seeds that will not be receiving water during dry periods in the winter and early spring. Scarifying stimulates all of the seeds to germinate and does not leave residual seeds for subsequent years in the event of a drought. In addition, scarification can damage some seeds. It increases the number of seeds vulnerable to extreme weather conditions and diseasecausing organisms. Scarification does increase the number of seeds that germinate, but will not guarantee a healthy, self-seeding stand of bluebonnets; many other factors influence the growth and flowering of bluebonnets once the seeds have germinated. The goal may not be to have a high rate of initial germination, but rather a productive stand of flowering Bluebonnets that reseed on their own without the need for replanting each year."
