Unknown ID on berry plant/weed

Question

I've had this plant growing in the garden when I moved into the flat over 2 years ago. It's growing out from a crack in the concrete so I think it may be a weed of some sort. Last year we pulled it up and sprayed the area with Roundup but it's come back lol

What is it? Is it a weed or plant? I am from South East UK.

Answer 1

I do not know what kind of plant it is.

However, the reason it came back after the roundup is because the roundup never got to the root.

Spray the whole plant, the roundup is absorbed through the leaves and makes its way down to the roots, where it kills the roots and thus the plant.  

Answer 2

Looks like a chokeberry of some kind.  Birds love the berries.  Lovely spring flowers, leaves turn a nice red in fall.

They sell them at nurseries around here.  I planted a couple myself last year.

But growing out of a crack in the foundation is not a good place for a shrub.  But Roundup is not going to work, since it's a woody shrub.  Roundup will kill the leaves, but it will take a lot of tries to get the root.  If you want it out, cut the stems at the ground, and immediately paint the cut surface with a brush killer.

Answer 3

This is one of the Hypericum species. A large Genus of approx 400 species of which one, St Johns Wort/Goat weed (Hypericum perforatumn) is just one of the more invasive species. The genus consists of trees, shrubs and perennials of which the latter mostly grow by rhizome. The one in your photos cannot be St Johns Wort as the leaves are too wide - it looks like a florist variety possibly H. x nudiflorum but from it’s ability to regenerate – obviously a perennial.

The trick in using Roundup as a control is to use it in strict adherence to the manufacturers recommended and application rates. Also I have found that first treating the plants with water and fertilisers and allow growth of the weeds first to achieve optimum growth and second to produce good quality and plentiful chlorophyll. When it is really looking great - spray the entire plant with Roundup/Glyphosate to the point of dripping. Do it early morning on a wind free and sunny day. Wind free because any overspray or drift landing on surrounding plants will cause damage to those pltans. On a sunny day because you do not want rain to was the plant clean shortly after spraying it. Do take care to use it when the plant is NOT in flower as you do not want it to affect bees visiting the flowers.

Sit back and do not remove any part of the plant until it is quite dead. This will happen in 7 to 10 days. Once the leaves are dying back, the roots and rhizomes will wither and die

Glyphosate - the active ingredient of Roundup - works on the chlorophyll of plants and is transported by the plant down into the roots with the starches and plant sugars produced by the chlorophyll / photosynthesis process. It is then in the roots system where it does the required damage to the roots and kill off any future re-growth.
