Thank you Vicky and Christine.
As much as I love Bluebonnets they don't seem to like my yard, either too shady, or too much clay, of too crowded so I have no luck with them.
Luckily they grow very well along the highways south of Dallas and not far from my house, so I have to content myself when I get to take some good pictures on some years.
I say some years because if the rain hasn't been forthcoming during the fall and winter, the Bluebonnets and other wildflowers won't be very good.
I think that in other areas of Texas they are more reliable, at least I hope so.
Nevertheless they are always an amazing sight when it all comes together and the miracle happens.
