We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
This kind of naturalistism is a mainstay of both traditional English landscaping and California Modern informality - the two parents of American garden design.
The problem for modern homeowners has always been scaling this approach down to small suburban lots. Which are growing ever smaller in established urban corridors. And may not have room for very many "vase and fountain" shaped shrubs, let alone a hedgerow have seen several of the plants in that article trained upwards to work as a small flowering tree in tiny gardens - a neat trick.
That leaves gardeners to seek dwarf, fastigiate, or creeping varieties that can be trained against a wall or fence to duplicate the effect of a "shrubbery" without hogging space. And then occasional pruning IS required. The upside is that a wider range of material is available.
It's still better than squared off topiary, and creates a private "green room" with seasonal flower/fruit interest, without devoting precious space to higher-maintenance flower beds.
Hack my forsythia to the ground every few years. If I don't it takes over 1/3 or so of my yard. Love it's announcement that spring is finally upon us, but nevertheless it gets pruned ALL THE WAY every 3 you 4 ears or so.
At this moment its a thigh high ball. It will likely be the next owner's decision next time it is too enormous to tolerate.
