Leucophyllum frutescens, most commonly known as the Texas Barometer Bush, is said to bloom before a rainfall. This bush in my front yard burst into bloom in the middle of one of the worst droughts Texas has ever seen about a week before the rains finally came to Central Texas.
The bees in my neighborhood definitely appreciated the pollen and nectar and were all over this plant.
Texas is finally getting some much needed rain, and we are expected to get up to 3 inches through Tuesday. Hopefully this is the start of better weather for Austin and perhaps a fall nectar flow is now not a distant dream.
