THEY LIE ABOUT THE COLORS

So this is my definitely-needs-staking delphinium that I've had in the garden for several years. But what's with that color? It's supposed to be Pacific Giants in a "range of rich colors." This is that washed-out pinky-mauvy color that so many plants revert to after a number of years, but it's been this color since day one. Every year I watch the buds form and wait with bated breath for a range of rich colors, but I guess that's not going to happen. No wonder I don't stake the damn thing.
