Texas Bluebonnets are surely one of the most popular Lupines all over the world. Texas lupine Texas Bluebonnets have larger more sharply pointed leaves and more numerous flower heads than similar lupines. Light-green velvety palmately compound leaves (usually five leaflets) are born from branching 6-18 in. stems. Texas Bluebonnet stems are topped by clusters of up to 50 fragrant blue pea-like flowers. The tip of the cluster is conspicuously white.In Texas they carpet whole fields and roadsides in the Hill country area. Also the Texas state flower is such a beautiful and spectacular flower. This ornamental with it's showy blooms is easily grown and provides nectar for bees & other nectar-insects. Like all lupine, these are very easy to grow and will quickly become a permanent fixture in your wildflower meadow or garden. The natural habitat for Lupinus texensis Texas Bluebonnet is praires, open fields, & roadsides where it grows in soils of limestone/chalky Sandy Loam Limestone-based Calcareous Sandy Medium Loam Clay Loam Clay Caliche
Lupinus texensis Texas Bluebonnet, the state flower of Texas blooms oceans of blue in the spring and forms attractive rosettes in winter. This is the species often used by highway departments and garden clubs. If planting this species in areas where it has not formerly grown it may be helpful to inoculate the soil with a rhizobium (soil-borne bacteria which form nitrogen-rich root nodules) for lupines. They will self-sow if not trimmed back. Still, probably because of its botanical name, the most popular is the Lupinus texensis, a rather short species with a deep blue color and dramatic white markings. In many parts of the country they are considered annuals. Texas Lupine wildflowers grow wild but they can be planted and will grow over most of the Midwest and Eastern US. Lupinus texensis Texas Bluebonnet is moderately deer resistant and has conspicuous fragrant flowers and attracts Butterflies. It is the larval Host for the Hairstreak butterfly Elfin butterfly. Seed Collection: Allow the bluebonnet to reseed itself by leaving the seed pods intact on the plant until they turn from yellow to brown.
Seed Treatment: Scarification will help germination. Put seeds in the freezer overnight and then douse with boiling water to crack seedcoats. Soaking seeds overnight is also effective. Drain water. USDA plant hardiness zones 4 to 9. Low growing but prolific blooming, Texas Bluebonnet Lupine requires some patience, but little maintenance, once established. The same toughness and tenacity that makes this little Lupine the perfect respresntation of the Lone Star state also makes it slow to germinate and bloom
|How To Grow Lupines from Seeds|
Growing lupines is as simple as planting seeds or cuttings into a sunny area with well-drained soil. If planting lupine from seed, scratch the seed surface or soal the seeds overnight in lukewarm water to allow the seed coat to be easily penetrated. Seeds of the lupine plant may also be chilled for a week in the refrigerator prior to planting.
This may also be accomplished by planting lupine seeds in the fall and letting Mother Nature do the chilling through the winter. Direct sowing of lupine seeds in autumn is perhaps the easiest method. Lupines produces seed which will re-produce more flowers the following year if not removed from the growing lupine.
Sow 4-8 weeks before planting out. Sow 2-3 seeds directly into cell packs.
Cover seed, as darkness aids in germination. Thin to one plant per cell or container when the first true leaves appear. Harden off and transplant outside. Keep growing container at 65-75°F, with germination taking 7-21 days,
Roots of lupines are fragile and once restricted will produce inferior plants and flowers. When plants are ready to transplant, do not delay planting. Established plants do not transplant well, so it is best to plant where they will be left undisturbed. OR
Direct seed: Sow seeds in early spring, as soon as soil can be worked. Sow 1/4" deep. Thin when true leaves appear.
