Jo and I try out the exercise machines on Bratislava's new Danube river promade - a real boost for the way you can enjoy the city and the river. The perennial revolution marches on! The Czechs and Slovaks are now doing research into public use of perennials, very much inspired by the German randomised mixing technique. Extremely interesting afternoon at the Landscape Dept. of the Slovak University of Agriculture in Nitra. Jo worked at Bratislava Comenius Univ. from 1993-5, so we now all about alcoholic Stalinist heads of department, reinforced concrete buildings , dead hand of Marxism-Leninism exams etc, etc. So delighted to find lovely new building, ditto perennial border, ditto prof, and young staff well clued up on all the German research, on Oudolf, and ‘the Sheffield school’. On the subject of profs. a sure sign of age is when the professors start to be younger than you are. Reading Prof. Hallova’s research I realise that she’d brought up an issue none of the rest of us have ever considered – that plants engage in chemical warfare through ‘allelopathy’ amongst themselves and that this impacts on planting combinations, so for eg. nepeta and euphorbia suppress the growth of asters and geraniums. I immediately think of all the Euphorbia cyparissias I let rampage in my borders. Fascinating! I think I should set up some trials back home this winter and really see if it is an impact we should really worry about in a practical sense. Perennial beds in every town I drove through! Plus trusty Renault Kangoo Given that it's a long time since I’ve driven round Austrian roundabouts it is just amazing to see how much perennials (in the 40-60cms height range) are used in traffic islands and roadside environments. Really just about every place I have driven through in Oberösterreich seems to. Wunderbar! A misty, soggy, chilly stomp around some dry meadow habitat near Mikulov in Czechia, Scabiosa ochroleuca and Aster linosyris flowering away in profusion. Sabine Plenk (a colleague from Vienna’s BOKU) and I agreed it was a ‘second spring’ effect as autumn rains re-moisten very thin stony soils. Nice to see the local flora (Pannonian-Pontic) used in the grounds of the castle in town in an ornamental way. Not so sure about the monstrous Christmas tree in the town square and all the artificial snow – but it turned out to be a film set. Made me freeze just looking at it. Dialectic of locally native dry meadow plants with box parteer at Mikulov Castle, CZ. More soggy foggy in Austria, can’t see the mountains! Furchtbar! Schade! However thinking long-tmer garden visiting in Austria is looking up. There is a new guidebook, published by Callwey Verlag and based on the very thorough Gärten Reiseführer for Germany. Lots of really rather nice sounding Privatgarten open too – how soon can I get back to check them all out? Only managed Linz Bot. Gdn. (good, some nice mature rarely-seen shrubs) and Christian Kreß’s nursery – Sarastro – at Ort-in-Innkreis. FAB, FAB, FAB. If this nursery were outside Guildford, you’d be blown away by it. Its not just plants, its really funky architectural salvage, kinky walls, alpines grown in all sorts of weird rubble. Its Berlin grunge meets Alpine Garden Society. Its cool. Ain’t nothing like it back home. Forget the Sleazyjet flight to ‘Vienna’ (in reality Bratislava). Get the car out – the GB sticker, the green card, the ferry/chunnel ticket, the headlight deflectors, and thrash down the autobahns (yes, you really can drive as fast as you like) and load the car up with plants. There’ll be loads here you’ve never seen before. And while you about it you can load up with Austrian wine, all of it totally gluggable and varieties like Grüner Veltliner you never find amongst the Chard and SauviBlank in Sainsbury’s, and the time spent on the autobahn will feel like its worth it. I did one better, stocked up with Slovak wine at the Nitra Tesco – just as good and miles cheaper. Stuff the Dordogne, up the Danube!
