Speckles Weak? Phals

[oregon woodsmoke]

I am wondering if the speckled phals are weaker?

I've purchased two different speckled (freckled) phals from different sources and neither one kept the flowers for much more than a week.

I bought my very first phals on Feb 20 this year. The plain ordinary pink one still has flowers. The other one, a harlequin, had flowers for along time. My newer purchases kept flowers well. Not like my pink one, but for a nice long show-off time.

It's just the two speckled ones that dropped their flowers quickly.

Fortunately, the plants themselves look happy.

Not quite off topic: my favorite iris is a reverse placata with a purple background and white spots. It is notoriously weak and the varieties bred from it are weak. That is why I am wondering if there is a genetic link between color and robustness in the phals.
