I really can't say, Mary. Sometimes it seems that certain varieties or even individual tubers have their own idea about when to grow. Last year, I had a dozen or more tubers that refused to sprout. Some were barely showing eyes by late June. I didn't want to give anyone a bunch of duds, yet I hated to trash them. I tilled another small area and started what I called a "tuber garden." I didn't really expect blooms by planting them in July but thought they might produce new tubers for this year. Wouldn't you know it? ... they started growing fast and several had blooms as good as the plants in the main beds. You never know.
I'm going out of town for a week. Probably early next week. I plan to take the tubers from the attic in the next few days and I hope they will start some growth so I can put them into planters when I get home. Hopefully, they'll have enough time to become "plants", without getting too leggy, when I set them out in early June.
