Powdery Mildews of Portland, Oregon

Posted on July 26, 2016 by Oliver Ellingham

Unsurprisingly the USA also seems to be full of powdery mildews. The Gallery below shows a small selection of those that have been lucky enough to be photographed by myself.

Young Mahonia sp.
Acer sp. heavily infected.
Lupin powdery mildew

Acer platanoides
The Grapevines were thankfully disease free,

Portland’s Rose Garden had many beautiful plants, but powdery mildew was also present.
More rose powdery mildew.

Basil powdery mildew growing at the roadside.
Powdery mildew on basil again.
Sweet pea are common roadside plants here and powdery mildew seems to follow them.

A healthy Heuchera.

    […] Throughout my trip I was on the lookout for my favourite fungus in order to see if its growth and favourite hosts varied much from the UK. I have collated these into a separate blog. […]
