Escaped garden plants in 2013

In addition to the 'weeds in my street' survey I will attempt to collect all escaped garden plants that I find in my daily surroundings. Deciding if a garden plant has gone 'wild' is not a self-evident task. A grape hyacinth growing through the cracks of the paving is obviously not planted but a Narcissus in a neglected flowerbed like above is a different matter. They are planted in parks and road banks throughout the city but a solitary one, hidden beneath a bush, has probably escaped, but how can one be absolutely sure? By noticing plants in unlikely situations elsewhere and by cross-referencing with similar projects (like and like) some additional certainty can be had. The distinction between a garden escape and a recognized wild plant is marked by a thin line. No sane gardener would plant a Giant hogweed or a Japanese hogweed even though both once arrived in Europe as garden novelties. Some plants are both planted by gardeners and weedy: the best example in my street is the Hollyhock that grows in abundance between the tiny space between walls and paving but at the same time you can buy three seedlings for a tenner at the market. 

A prediction: personal ignorance will make it hard to find the exact name for all plants. Your help is appreciated.

The matter of escaped garden plants is a hot topic: after three generations in the wild and when seeding, plants are recognized by the Heukels Flora (the Dutch botanical bible) as native and we are now undergoing an unprecedented influx of new species. The last edition (2005) claims 8% more plants than the 1996 edition and I remember reading or hearing somewhere that the next edition will at least repeat this increase.

All and all this should be an interesting enterprise.

The caper spurge (wolf milk in Dutch) escapes with the garden refuge. Interesting addition. 

Servian bellflowers (I think) growing in a sunny spot around the bend.

Some kind of viola, a plant that I, perhaps unfairly, associate with old ladies.   

The wood forget-me-not is a popular garden plant and well known for escaping. I have spotted a few of them at different places and expect to see more them in the years to come.

A reader suggested annual honesty rather than sweet william catchfly and I think he must be right. It is common this year, I don't remember it from last year.  

The wood viola is occurring at several places, always in tiny patches like this one. Not sure about the name.

Here is an orange hawkweed (thanx Herman) from a municipal flower bed, three meters away.

Escaped from municipal flower bed (see curb)  

Another viola with different colors.

See on Selborne

Again escaped from flower bed

Ghastly plant for right-wing above 65. The detail shows very unclearly shows blue flowers amidst leaves that normally I would recognise as wood sorrel. Any ideas?

I saw tens of this plant in the corner of a building and I think they are potted plants that escaped through a broken bin liner. After months they have finally flowered. Any idea for a name?

Unclear pic, but I assume it is a garden escape.

Another pic drowned in sunlight and photographic incompetence. A popular garden plant this. Next to it

Alkanet, a plant now well established.

No Idea about name.

2 plants, equally ugly, no names.

The flowers look the same as the plant above but it's form is very different.

Common foxglove, one of the witch herbs. It may be wild.
