The B. blechnifolia is a fabulous species, and a favorite of mine for mixed container plantings. The new foliage is so soft and fern-like with lovely soft pink coloring. The growth habit is rather distinctive as well, as this one is a ground cover that forms rhizomes along the ground. It combines beautifully with succulents such as Graptoveria 'Fred Ives' and Anigozanthus flavidus.
The University of California at Santa Cruz Botanic Garden has an excellent collection of many species of Banksia, which thrive on the nutrient poor marine terrace sandstone soils of the campus, right next to our native Quercus agrifolia and Sequoia sempervirens.
