Until a day or two ago, it was feeling quite springy around here – longer days, mild daytime temperatures, and I’d begun the flurry of client interviews and site assessments that typify my spring schedule. Then BAM – old man winter returns with a big dump of the white stuff.  Lucky for you, this means a short reprieve from aforementioned activities, and I can work on this post. Next in the plant form series is weeping form.

Weeping Form

Weeping plants can be huge trees like Betula pendula ‘Laciniata’, or small grafted specimens like Betula pendula ‘Youngii’. The large weeping trees have less distinct form because there are countless branches, each with delicate drape – the resultant outline of form is therefore somewhat amorphous, though still quite elegant.

To me, they bring a sense of quiet luxuriance to a landscape, perhaps because I associate this form with the giant weeping willows that reside near still waters – the picture of both opulence and serenity.

Although these big weepers lack definitive form, their lacy texture makes them lovely feature trees – if scale and proportion allow. They are especially lovely as waterside accents and make elegant shade trees – again if the size of your house and/or property allows.

Small weeping trees offer much stronger architectural form than their larger counterparts– their arched weeping branches create an umbrella-like form. Many of the weeping specimens available at nurseries are actually low-growing creeping shrubs that have been grafted onto a standard, for example Young’s weeping birch, Walker’s weeping Caragana or Rosy Glo weeping crabapple.

This form draws the eye up … and back down again. It is strongly dominant so should always be used as a single specimen – I can’t stress this enough. Don’t try to group them in threes, or use two to frame an entry, or plant several in linear fashion – it just doesn’t work. I made the mistake of planting two in my front yard several years ago – you can read about it in my post from last year around this time: Form, Colour and Texture in the Winter Garden. The bottom line is, any more than one and they’ll just compete for dominance and create visual unrest. So one is enough – got it?

A weeping form makes a nice centrepiece for a symmetrical composition. Left – Caragana arborescens ‘Walker’s Weeping’ in a client’s raised planter. Right – another of those pretty scenes I periodically drive by, C. arborescens ‘Walker’s Weeping’ in winter still has strong form. Photos: Sue Gaviller

These small weeping trees are useful for highlighting architectural details, like arched doorways or windows – the arching form of the branches mimic the architectural line, thus bringing attention to it, and creating unity (by repetition).

Fountains too, can be ‘echoed’ in this way with the placement of a weeping tree nearby.

As well, a weeping form looks very appealing at the top of, or near a slope – the weeping branches reiterate the sloping line of the hillside.

And don’t plant one of these feature trees in the middle of an expanse of lawn where it will appear lonely and insignificant – it’s much more effective when staged and supported by the presence of other plant material.

I’ve had several clients tell me they don’t like the shape of weeping trees because it makes them feel sad (maybe it’s the name – y’know power of suggestion and all). I don’t get this. To me weeping forms are graceful and very pleasing to the eye. Indeed their appropriate use demonstrates a mature design sensibility. I guess it’s a humble reminder for me, and all you aspiring designers, that there is a degree of subjectivity in design that must be acknowledged and respected. And with that little piece of wisdom my friends, I shall bid you adieu.

More “Fun with Forms” in my next post – see ya then.
