Good native for a difficult spot.

[osopolare]

Hello Folks,

I'm looking for suggestions for what to plant in a difficult spot in my yard. Everything else I've planted there has died.

It's right in front of my front patio, so the spot is on the north side of the house, adjacent to the foundation. It's about 5' x 5'

My home is located in the foothills of Altadena.

The spot I'm looking to fill gets a lot of sun in the summer but is shaded well by the house in the winter.

This spot is right where our gutters terminate so in the winter it will get completely flooded and waterlogged for a few days each year.

There's a bunch of spider plant that grows right next to it and that stuff gets killed in this location, just to give you an idea what we're talking about.

I'm imagining that there is some sort of riparian species that would do well there. Something that's used to growing down in the canyon, tolerant of shade and fine with getting flooded. Any thoughts?

Thanks for your help, I'm pretty new to gardening and to using natives beyond that.
