Allo allo allo, what's been goin on 'ere then

[David Humphries]

Aesculus hippocastanum with serious leaf discolouration.

 

Putting aside the obvious Cameraria infestation, the Tree has this condition over the entire canopy.

 

Considered that it is possibly some sort of macro nutrient deficiency, but would have thought the veins would still be green.

 

The Tree sits close to others in a small grove of Hc and is the only one affected

 

Interestingly, this Tree appears to be hosting far fewer Leaf miners than it's neighbours.

The total lack of green says genetics to me so I think you have a variagated A. hippocastanum which has reverted more or less totally with a few remnants.

 

Bean 1970 notes that a few variagated varieties were introduced as early as 1775 but are only to be found in old collections... That might descibe your site???

 

Interesting that it is predated less...

And Hilliers Manual 2007 notes a rare pale yellow leafed variety called A. hippocastanum 'Hampton Court Gold' deriving from a small tree in the Hampton Court wilderness garden...

 

Also there is another yellow rareity named A. hippocastanum 'Honinton Gold' listed in my Collins by Johnson and More 2004...

All good stuff Tony, cheers.

 

To be honest I only spent a nano second having a butchers at it as it started bucketing it down.

 

Hopefully will return to the site before the full force of fall, and look a little closer at this Tree.

 

Stay tuned
