UNITED STATESGood old fashioned suburbia will never bee the same. Bigger modern homes on smaller modern parcels leave little space for gardening and trees. What is not shaded by the taller homes is shaded by the taller fences, which are ”˜needed’ for privacy since the homes are closer together. Building codes in most municipalities limit the height of fences, but lattice screens are often added on top for extra height.

Because lumber is not of the quality that it was when shorter light duty redwood fences were built decades ago, relatively expensive modern fences do not last nearly as long. They might last longer if they would get repaired instead of replaced when only the posts rot. Green technology seemed to work better before it became trendy.

Ironically, no one wants these bigger and bolder fences that are closer to home to be so prominent in the landscape. We try to obscure them with vines that can tear them apart, or shrubbery that can push them over. Watering these vines and shrubs accelerates rot in the posts.

Shrubbery intended to obscure a fence should not be so voracious that it wants to displace the same fence that it is intended to obscure. Some types of pittosporum work nicely because they support themselves without leaning against other features in their surroundings too much, even if they eventually get quite large. However, they do get quite thick, and can obscure a fence so well that no one would miss the fence if it were to get pushed over! A good hedge without a fence is sometimes a better option.

Many types of vines can be kept much closer to a fence than shrubbery can, but most tend to be more destructive. Star jasmine works nicely if allowed to climb a trellis directly in front of the fence, but should not be allowed to get between planks in the fence, or to get too intertwined in lattice. If it gets too fluffy, it can be shorn back like a light hedge.

Clinging vines like creeping fig can be very appealing on fences, and can be shorn like hedges, but will eventually necessitate the replacement of the fences that they climb. For those who appreciate such a tailored appearance, replacement of the affected fences every few years is a fair compromise.

Highlight: Toadflax

Toadflax really does look like baby snapdragon, which is its other common name. The tiny, half inch wide flowers are similarly bisymmetrical, and arranged in small trusses, although the diminutive leaves are distinctively narrow.

Common toadflax, Linaria maroccana, which is actually less common than the name implies, gets about one and a half to two feet tall and about half a foot wide. Two toned flowers bloom in summer in shades of pink, purplish pink, purple, blue, very pale yellow or red with yellow. ”˜Northern Lights’ adds shades and bicolor combinations of yellow, orange and red to the mix. The more common ”˜Fantasy Hybrids’ get only about half as tall and perhaps slightly wider, with earlier and slightly larger flowers in shades of yellow, blue, pink and bright pink, as well as white, mostly with slightly yellow throats.

Toadflax is a summer annual, but does not like to be too exposed to roasting heat and glare. If grown from seed, it should be sown as soon as possible after the last frost to get an early start.
