This is one of the few places that bluebonnets are flowering this year. Most of the ones outside the walls have shriveled up due to the lack of rain. I think it is now too lat to expect any blooms from them. I hope we have a good seed bank. I think they have done better in this garden because there is a good layer of granite beneath the gravel, which tends to hold more moisture.
I may not be able to achieve a wildflower meadow, on the septic field, as I would like, but have no problem in the gravel garden. I am more than happy to leave the blackfoot daisies, four nerve daisies, bluebonnets and grasses to create their own garden.
