I am not quite gone yet; on Wednesday I start the long haul over to Barcelona and then the south of France. In the meantime, the rockery has been bringing me much pleasure. If I ever have to downsize both house and garden, I might be tempted to turn any new, smaller garden into rockery. Rockeries lend themselves to highly detailed, high-interest level gardening and I can see I could be quite happy pottering in a rockery – as indeed was Mark’s dad, Felix, in his later years. It is a particularly absorbing area to garden, even if there are times I regard it as the gardening equivalent of micro-surgery.
Ours is a raised rockery with different levels so it has detail in its design, not just in its plantings. Mark’s mother always used the plural ‘we’ when she talked about building the rockery, but we think it more likely that she designed it and then supervised Felix in its construction, which included some excavation to achieve different levels. Every original garden structure here was done by hand or, on occasion maybe, using horse power. Felix did not have a tractor or access to any of the machinery we can call on these days.
As our rockery measures some 20 metres by 10 metres, it is not small and it is certainly not low maintenance. Because it is largely raised beds and pockets of soil for separate plantings, it dries out and heats up in summer. Our frequent heavy rains drain quickly but that also leaches a lot of the nutrients out of the soil in the process. Bulbs generally need excellent drainage and many thrive in poor soil so they are quite happy in this environment. We try to get around with a thin layer of compost every spring and when I excavate a pocket to sort out its contents, I will add compost when I replant. But the soil overall is pretty impoverished and generally lifeless in the summer heat. There are almost no earthworms in summer but they seem to return as temperatures cool.
Rockeries are traditionally a re-creation of rocky mountain slopes to grow alpines. We can’t grow alpines here where our conditions and climate are anything but alpine. Our rockery basically consists of elderly dwarf conifers of considerable character and a few cycads giving all year round structure, offering some shadier areas beneath for bulbs of many descriptions. Smaller bulbs and many species rather than bigger hybrids which look out of scale, with one notable exception.
That exception is the Nerine sarniensis hybrids, most of which were bred and selected here although we have a few of the early Exbury ones and some of the species nerines. They are sensational at this time of the year. Along with Cyclamen hederafolium and the ornamental oxalis, they keep the autumn rockery full of blooms and colour.
Last year, Zach reassembled the oxalis collection. Years ago, I planted them all out because I didn’t want to be repotting them every year and he set about retrieving some of each. We had only lost one or two inbetween times and he now has over 30 varieties in pots – most from the garden and a few extras he has picked up from local markets.
A much maligned genus, the oxalis shine at this time of the year. We are only a few months off the short snowdrop season and the start of the dwarf narcissi and lachenalias. There is always something of interest going on in the rockery and it is constantly changing as different bulbs and plants take their time to shine. Always, Mark and I remember Christopher Lloyd saying in conversation on a TV programme, “I think you will find high maintenance is a great deal more interesting.” We could not agree more.
