The 4th number plant looks awesome... If any one figures out its name, Im gonna search It for my backyard :D
Shoot shoot shoot. I had #4 in my garden but I've forgotten the name. It's in the Liliaceae or Iridaceae, I can't immediately recall which.... My first though is Quamash, but your distribution is wrong for that. Anthericum spp or cultivar, perhaps? other possibilities include Orthrosanthus and Tulbaghea. Smell will help tell you - Tulbaghea has a garlic or onion odour when rubbed.
