Physocarpus opulifolius var intermedus 'Dart's Gold'
Phagat says (Don't you love Phagat? Follow the link if it's new to you.)
"Three-lobed leaves emerge golden in March & age to lime-green or chartreuse in summer, then back to yellow & bronzed red in autumn before leaf-fall reveals the upright twiggy structure with vertically-cracking exfoliating orange-brown bark on the oldest twigs.
In June & July, the arching branches produce two-inch terminal pompoms of tiny white flowers with pink shimmer. These turn into red seeds about September, which are like another flowering, so that 'Dart's Gold' has multiple phases of beauty."
Physocarpus opulifolius 'Monlo' Diabolo® purple-leaf ninebark
The leaves emerge deep purple, which is beautiful in spring. The color fades to green or purple-green in hot, humid climates. The patent owner, Monrovia says Monlo diabolo likes the west coast's moist acidic soil.

Best in full sun in the northern part of its growing range, but appreciates some afternoon shade in the St. Louis area. Tolerates a wide range of soil conditions. Prune as needed immediately after bloom and no later than mid- August."
