Had to look up Iris tigridia, it is beautiful. We are having the same problem here in No CA. Our early peach tree bloomed and everything froze without setting one peach. We are expecting a freeze tonight but luckily everything else isn't blooming yet, but getting ready to. Wayne is so excited about his fruit trees that he is really disappointed that we won't get one peach on the early Alberta. He also walks the garden daily looking for bees. He put out mason bee houses last week. I finally got some gourd seeds in the mail to you, sorry it took me so long. The School Garden Workshop was a huge success but consumed my life. I still have paperwork to fill out and receipts to turn in. Glad it is over. Now arranging the scheduling for the SF Flower and Garden Show that begins next Wednesday. Carolyn Craft
