In previous years, in addition to 'Aurora', I have grown 'Clear Springs'. However, this year it was dropped from the GeoSeed catalog so I am instead growing 'Magic Fountains'. 'Magic Fountains' is an older strain, kind of a dwarf 'Pacific Giants'. There are more separate colors available than in 'Clear Springs', and you can get white and dark bees, which is kind of cool. So why haven't I grown them in the past? I think I had the impression that 'Magic Fountains' was maybe a little too short, plus I always had such good success with 'Clear Springs' that I had little incentive to try something different.
In addition to the Delphinium cultorum 'Aurora' and 'Magic Fountains', I am also starting some Delphinium belladonna 'Oriental Blue'. I grew this a couple years ago but unlike the other Delphinium belladonna I had grown, most of them died after the first year. They bloomed at the same time as Clarkia and looked really nice with them, so hopefully I will have that pairing again this year.
