During a recent meal with friends I learnt a new Three Letter Acronym (TLA): DMC or Deep & Meaningful Conversation. And it struck me that like most activities, gardening has its fair share of TLAs, about which there may well have been some DMCs.
So before we all go MIA (Missing in Action) for the Christmas and New Year festivities, I thought I’d share a few of the obvious horticultural TLAs. When it comes to late winter we can lavish much TLC (Tender Loving Care) on our gardens with an application of WRM (Well Rotted Manure). When pruning mature shrubs we should be using the mantra DDD (Dead, Diseased, Dying). I would argue that useful as this is as a guide, it doesn’t include the reminder to eliminate those crossing branches which rub together, potentially creating a site for disease to enter.
Having prepared the garden to withstand the winter, during any quieter times ahead we can plan new planting schemes, perhaps inspired by a gardening book received as a Christmas gift. One of my favourite sources of ideas for combining shrubs with herbaceous perennials, is ‘The Creative Shrub Garden’* by Andy McIndoe published by Timber Press. The book groups garden styles and colour combinations, with the shrub suggestions supplemented by ideas for complementary herbaceous perennials or grasses. There are also expanded schemes for larger gardens. I heard Andy McIndoe speak at a lecture a couple of years ago hosted by the Kew Mutual Improvement Society (KMIS): a FLA? His enthusiasm for his garden in Hampshire and practical approach was infectious and inspiring.
Many of the cultivars listed in my now well-thumbed copy of the book bear the epithet AGM indicating that they have been awarded the Award of Garden Merit by the RHS (Royal Horticultural Society). This means the RHS has trialled the plant in question and that it fulfils certain criteria including that it is ‘excellent for ordinary use in appropriate conditions’, ‘of good constitution’ ‘stable in form and colour’ and reasonably resistant to pests and diseases (PADs?). It must also be available which of course makes perfect sense as there would be little point in bestowing the honour upon a plant no-one can get hold of. I have read that if for some reason it is not practical to trial a plant, the RHS might award the AGM after a roundtable assessment by a forum of horticultural experts who debate its characteristics and garden performance.
I recently planted climbers in a couple of clients’ gardens, and each plant bore the reassuring AGM suffix. One was Trachelospermum jasminoides AGM, commonly known as Star Jasmine or Confederate Jasmine. I see from the nursery label that it has recently been renamed Rhynchospermum jasminoides. This perfumed white flowered evergreen ticks so many boxes in terms of being a good ‘doer’ for clothing a fence or wall. It needs some support whilst getting established, either on a trellis or strainer wire, but in due course it thickens up and supports itself and I have seen it entirely framing a friend’s back door.
The other AGM climber I used was Clematis ‘Ernest Markham’ AGM whose flowers are described as velvety crimson-red on the RHS website. It looks unremarkable at the moment but I hope to see it in flower in the client’s garden in early to late summer.
My client with the cottage style garden full of unusual shrubs (which I wrote about in a recent post entitled The Generous Gardener), told me a couple of weeks ago that she plans to plant an AGM shrub this coming year which she read about in the December issue of The Garden (page 82), Heptacodium miconiodes AGM. The common name of this autumn flowering tree is the wonderfully evocative ‘seven son flower tree’, which hints at its origins in China. This is another plant with fragrant white flowers and I understand they are very attractive to bees. Pink bracts remain when its flowers fade, lengthening the season of interest well into the autumn.
No doubt there are many more TLAs applicable to or peculiar to horticulture and I am now on the look out for some more to add to my list. Before I start my quest, I wish you a happy Christmas and a successful and satisfying start to the new decade.

DDD is a TLA?! Wow, I never though of that. I actually used a TLA long before it became cool to do so!
