Thursday Garden Favorite - Acanthus mollis “Grecian Pattern Plant”. In some cases this plant might be considered a bit invasive but for years I had planted dozens of different plant material under my giant Sequoiadendron only to watch it fail. I purchased one of these plants back in the 80’s, dumped it out of the nursery pot and it hit the ground hard breaking several sections of root off. I planted it at the base of the Redwood and then dug two more holes dropping the pieces of roots into those. In no time I had three plants. The flower spikes appear every other year. They give the garden a bit of a Jurassic Park look.
