Advanced Keto BHB Indian Umbrella. The pretty orange and red petals of this flower, with bright yellow tips, look beautiful within your Houston wildflower garden. A Texas native, plant this flower entirely sun within the fall; it needs to bloom from May all through October within your wildflower outside. It is drought tolerant, but will die if Houston experiences an extended freeze. It is a Keto Diet wildflower that is a nice choice for Houston container gardens.
