Osteos thrive everywhere down here madpenquin and I grow several of them
is dead heading necessary? It depends on vwriety and habit I think. I grow wide clumps of a particularly large flowered white variety of eklonis. It flowers non stop.....from early spring through to late autumn. for appearance only I think, I remove the spent brown flowers which can spoil the white effect if not removed and I do this every couple of weeks or so by removing the entire stems.
for smaller less vigorous varieties like Silver Sparkler, Voltage Yellow, etc., I try to deadhead more often as I think flowering would be affected if not done.
so, not just for prolonging flowering but also for appearance sake deadheading is beneficial
