Field Notes: 
Pampas Grass is highly adaptable and can grow in a wide range of environments and climates. It also seeds prolifically, with each plant able to produce over 1 million seeds during its lifetime. As such, in some areas (for example California, Hawaii or Green Spain) it is regarded as an invasive weed, whilst in New Zealand and South Africa the plant is banned from sale and propagation for the same reasons.Removal of Pampas Grass by burning will not always prevent return. Chemical weed killer will kill the grass at the roots. 

It was named by Alexander von Humboldt in 1818.

Common Name: Ivy

Scientific Name: Hedera sp.

Native to:
Bloody Europe

How it got here: 
Same way the Irish did.
 
Field Notes:
This Ivy is the new hidden scourge.  As it looks so quaint and reminiscent of days of English lore, this weed of malevolent intent is ready to invade and corrode our homes and places of recreationOur Forests are being choked by this unchecked and hardly regarded weed already.  The English Ivy that is now taking hold of your siding and stucco, brick and bracing, concrete and crevice, walls and weakened wooden structures will cause failure.  Ivy is a nemesis equal to the Himalayan Blackberry, with difficulties unique and even more difficult to eradicate due to it's creeping and corroding habit.  The last battle will be between the bramble and the vine.
