John, they all look great.
Two of min, 'Gold Mine' and 'Copper Canyon' are staying healthy, but the sun has bleached out their color. They are in the furnace bed.
'Steel Appeal' is keeping it's color in the furnace bed, but it also has a bit of shade from an erodium.
The other two, 'Gold Rush' and 'Choco-Latte' are in the other bed, full sun but no reflected sun from the house, they are doing great.
