Gardeners' Notes:


On Jul 25, 2015, limpit from Resaca, GA wrote:

Bluebonnets have been reseeding and growing in my rocky NW Georgia soil for the past seven years. However, if native grasses and weeds are allowed to compete, the bluebonnets they will soon be smothered out. They usually germinate here in late August to mid September and are in full bloom by mid to late April.

Most folks aren't aware of this bit of TX bluebonnet germination info --

Only one-third of the seeds are primed to germinate the spring after sowing.
Another third are genetically programmed to germinate the 2nd spring.
And a final third will wait until the 3rd spring. This is so whether your TX bluebonnets are supposed to blossom in hues of blue, red or white. This is the characteristic of how the seed coating breaks down to allow moisture to reach the dormant embryo within.

So it's not unusual for bluebonnet seeds not to meet the expectations of some gardeners. Patience is required. Or you can be proactive!

Scarify those tiny seeds by rubbing against an emery board, then soak them in warm water for 24 hours before sowing them... read more

This is a beautiful plant that does well in Louisiana if planted in well-drained soil with lime. I have never seen it self sow here.

My bluebonnets started from a couple of plants our grandsons gave us when we moved into our new home 4 years ago. I usually let them seed out and they just get prettier each year. However, this year I am anxious to mow them down and get my yard prettied up again. Should I mow them or pull them up and put them in my garden?

The Texas Bluebonnet grows wild on my property facing Hwy 59 between Cleveland & Livingston.
I have taken seeds and redistributed them.

In my Florida garden these are a short lived annual. I get them every year from a nursery friend that I trade seeds with. I will be putting my plants in the ground in the next couple of days and they will do beautifully and be in full bloom by mid April. When May gets hot, they will be gone for another year. But for the weeks I have them, I adore them.

I remember seeing these near fort hood when my father was stationed there when I was in elementary school. They would flood the roadsides between where we lived (Copperas Cove) and Fort Hood every spring with blooms.

I live an hour north of Austin, TX. The bluebonnets are beautiful here. In my pasture, however, the first year, the flower was tiny, tiny, (as Crimson noted). I blame myself because I planted waaaaay late. This year again I thought, "oh no, I have to plant more, this time following the directions", but, I guess, since I planted late, the flowers came late, plus they are bigger. Since they self sow, I can't wait to see how big and how many I'll have next year. Hang in there Crimson blessings are coming your way.

I started mine from seed and have had excellent results. I am a native of Texas, but now reside in central Missouri. I missed the bluebonnets of my childhood. I purchased seeds at my local store. I didn't follow the directions exactly on the packet, but I still received great results! Now I have a piece of my childhood growing in my Missouri home!

I finally got these bluebonnets to grow this year and they are still going. Love how they looked with this firey freesia too!

This beautiful flower comes up in early spring, blooms, seeds, and dies back to the ground. In this area at least, it self sows so consistently that it has the effect of being a perennial.

I'm a beginning gardener and was able to grow a very nice patch from seed on the first try. The seeds I purchased were labelled as "scarified for easy germination". I sowed them on top of my mulch and lightly raked them in the fall and kept it damp until they germinated. I was rewarded with my very own bluebonnet patch this spring.

San Antonio, Tx.
The seeds can take up to 2 or 3 years to germinate and must be planted in September or October. I have done better with transplants. I used to kill the poor things planting them in organically rich soil, fertilizing them and providing too much water. None came up from self-seeding in my flowerbeds, but several were growing in the cracks of the street asphalt. They will grow in gravelly and/or rocky soil and do just fine. I have found that the maroon ones have fewer blooms, do not grow as tall nor wide and do not show up in the landscape as much as the blue ones. Each year I tell myself I am not going to plant the maroons and each year I do hoping that they will perform better.

The sides highways in the area are blanketed with bluebonnets her in DFW from about the end of March into May. For years my mom tried to grow them in the yard, both from plants and from seed, with no success. Unfortunately, she was meticulous about maintaining an organic program in the yard. This resulted in a very healthy yard, but not bluebonnets! It seems to me that they do best in poor soil and when they are largely ignored when feeding and fertilizing the other plants in the yard!

Apparently our Central Texas climate is perfect for these to thrive, or is it the alkalinity of our soil? Fields so thick with blue blooms, atop plants that reach up to 18 inches, that they look like a blue quilt spotted with white are a common sight in this area ~ all without any intervention from man. Gorgeous!

In atleast half of the large stands, a plant or three can be found with white or pink blooms (dark pinky-maroon, light pink and all shades in between can be found). The "Maroon" variety was isolated from seeds found growing in San Antonio, I believe along the banks of the river near the Alamo. The legend of the "Red Blubonnet" is that they were stained red from the blood of the defenders that lost their lives there. White has also been isolated for purity and... read more

I'm very disappointed, my seed was from a retail pack and the results were 4" light pink (Was supposed to be maroon) and blue tiny plants with flowers so small it would be amazing if they could produce a single seed.

For southern and arid climes this plant is perfect for early spring color. Does not do well in humid regions. Left undisturbed these plants will reseed and expand.

Bloom from summer through fall in cool climates and from spring until weather turns hot in warm climates. Poor to average soil. Leaf blight, leaf spot, crown rot, powdery mildew, and rust may be troublesome.
