I love Lamb's Ear's as well they are very useful and a lovely scent on a hot day if you brush by them. Honey will be fine, we have had this as part o the floral source for years. And like you I just wait for the bees to finish getting there food before cutting the flower's.
Well, I've learned something new today. Lamb's Ear flowers are indeed fragrant! I never knew. I couldn't get it to release much scent by brushing by it, and the bees were starting to get a little annoyed with me, so I thought it best to stop, lol! But they do smell nice! Thanks for sharing that!
