This post is not about cats wanting in, then wanting out, then wanting in again, but about plants that leap the garden wall. Because we are in the middle of a wild area where numerous animals might be interested in the garden and especially its plants (deer, hares, skunks - their specialty is digging up looking for grubs - groundhogs, etc...) the garden is all fenced in. There is a strong contrast between the inside, where plants face little competition, and the outside where it is the jungle. Not only are there plants that sneak in from the outside - as is to be expected, weeds will seed themselves in, but, more surprising, are garden plants that move outside the fence to settle, sometimes very successfully among the weeds. I suppose, like William Kent, they "leaped the fence, and saw that all nature was a garden".

Some of the weeds that get to seed themselves in the garden are sometimes welcome, for instance this OxEye Daisy (Chrysanthemum leucanthemum). When a plant decides, like this one, to grow just in the perfect spot, it is difficult to get rid of it, even if there are a million of the very same plant just outside the fence.

Another example of an intruder is this buttercup (Ranunculus repens) which has been granted a reprieve until it finishes blooming, as it cheers up a rather boring shady border.
As I said above, though, what is most surprising is that some garden plants leap into the fields and start prospering even when they have to compete with much more muscled plants. The best case in point is Sweet Williams. There are two patches of it outside the garden. Neither one was planted or seeded, and these patches keep growing from year to year. The flower-heads sport a more modest number of blooms than those of their garden brothers but, on the whole, Sweet Williams "beyond the pale" do better than the ones that are cosseted inside the garden.

A small speedwell has also taken to the wild. We have several cultivars of that plant inside the garden (such as Veronica Waterperry Blue) but none that are exactly this blue. I don't know if one of these cultivars has hybridized on its own or if I simply forget we used to have it in the garden. Anyhow, it has also leaped the fence, and it grows scattered here and there on long stems, rather than clumping on short stems as all the cultivars in the garden do. No doubt the way it grows is explained by the intense competition.
My last example of a garden plant that has taken to the wild is a cranesbill (Geranium sanguineum). Inside the garden, the flowers are smaller, but much more numerous, and grow in a dome shape.

However when it seeds itself among buttercups, Queen Anne's Lace and other weeds outside the garden, the blooms are slightly larger, and there are only a few of them growing on tall lanky stems to weave itself through their neighbours to get at the sun.

I supposed the conclusion to be drawn is that even plants do not accept boundaries and will leap the fence whenever they can!
