Iris pseudacorus 'Variegatus' problems — and how to fix them
Iris pseudacorus 'Variegatus' (Iris pseudacorus 'Variegatus') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Variegation fading
Cream striping naturally greens up after flowering as temperatures rise; this is normal, not a deficiency.
Invasive spread
The parent species is a listed invasive in many areas; grow in a contained aquatic basket and remove seed heads to prevent escape into waterways.
Iris sawfly and leaf spot
Sawfly larvae chew leaf margins and fungal leaf spotting marks foliage in stagnant, crowded conditions; remove affected leaves and improve water movement.
Drying out
If the rootzone dries, leaves brown at the tips and the clump weakens; this is a bog plant that must stay saturated.
