Acer Negunda

[Alinicoll]

I worked on an old Acer Negunda (Box Elder) today. No pics but could get some if useful. There is a certain amount of compaction around the roots and a far bit of basal epicormic. The odd thing is that alot of the new epicormic growth is pure white!

 

Anyone known why that might happen?

Its probably a sport. Some species are prone to genetic mutations, which is where cultivars that are variegated or have an unusual habit of growth come from. A pure white variation would not be viable however as it has no chlorophyll and therefore cannot photosynthesise.

Just one of those things then! Ineresting.

Weed killers can have a similar effect. But unless it was on Council owned land that probably wasn't the cause in this instance.

No it was on a private driveway, weed killer is possible but unlikley.

 

Cheers.
