When Penny and I first started Diggers, we would regularly travel up to Trentham from our block in South Melbourne to visit Dennis Norgate’s nursery. Norgates was the first-choice destination for our perennial selections as Dennis was doing things that no one else was; he was way ahead of any other plant-growing nursery at the time. 

Delphinium ‘Blue Sensation’ was one of our selections from Norgates’ range. It was a standout for its incredible colour (ranging from light to intense electric blue), its unusual size (being shorter and multi-stemmed compared to traditional, taller, single-stemmed delphiniums), and its repeat-flowering ability. It doesn’t need staking and is much longer-flowering than other varieties, given its ability to produce new flower spikes after deadheading. 

There still isn’t anything quite as good as this unique free-flowering variety.
