I have never heard of this coming at any time of year, but in California they have flowers in the desert in March. But the flowers are only good if the rain came at the right time and hard enough. People track this and tell you when to come. One weekend they are there and the next they are gone.
I'm so happy for you to have these sprinkled all over. What a wonderful gift of nature.
On our West Coast we have the Namaqualand Daisies in Spring, I have yet to visit when this happens Sharon, we are East Coast dwellers, conditions completely different.
Ah, I see. I usually like the west coast better for the dryness, but any coast would be good right about now!
