Hi Christina,
to NGA
N. CA zone 8... Hmmmm... did you move to Oakdale?
I suspect you have powdery mildew on your vegegables - your garden looks shady. Its a common problem with wet springs and plants that require full sun to do their best.
Your last photo are orchids! Bletilla striata - Hardy Orchid. They are terrestrial, like to stay damp and enjoy some shade. Your's have already bloomed but will be pink or white (actually very light pink). That's why I asked if you moved to Oakdale. I think I gave Bletilla to everyone on the east side before I moved to Reno.
