'Avant-gardists will tend to pick strong plants that grow especially large,' says Klaus Wagener, a world champion florist from Minden.
Guenther Sator, a feng-shui expert based in Mattsee in Austria adds that avant-gardists love succulent plants because they grow in unusual shapes and are easy to care for.
'Thanks to their slow growth, you can retain their structural elements for a long time,' he adds. Smaller plants can be arranged in a glass bowl or ceramic block filled with sand, rocks and gnarled roots to create a miniature desert garden.
Cacti are another good idea. 'You create attractive views, scenery and niches by potting them in large earth toned, sand-filled pots,' says John Langley, a professional florist from Hamburg.
