@jbogard I love the bark of your blackjack oak. Nice.
Maybe a flower bud on a deciduous azalea 'White Lights'
New buds on a weeping flowering crab apple. My only grafting success, all the branches were grafted on by me, onto apple understock. I have misplaced the cultivar information. Due for a repot this year. A few weeds and a couple suckers from the understock will need to get removed this week.
