Oh, boy, lots of photos. Such healthy foliage! Pinstripe is just adorable.
Your "Banksia" looks like Cecile Brunner.
I love Laburnum. It looks so good on a long arbor. Sonoma Horticultural Nursery has one section with nothing but yellow plants, and the centerpiece is a long arbor with lots of Laburnum planted on both sides. It's a spectacular sight in bloom.
