NC State Extension

Delphinium ‘Aurora Deep Purple’

Trial: Annual

Years Trialed: 2002

Good Qualities

Gorgeous purple flower (4); Stiff stems, nice full florets, overlapping petals; Being a delphinium is a good quality on its own, this variety didn’t stand out in any way; Nice full spikes, and good vase life – Will grow again; Seemed to be more heat tolerant than ‘Pacific Giant’ Series – Also, more compact/sturdy flower and plant with less susceptibility to toppling over; Big, beautiful stems, striking petal/ bee contrast; Very strong even when grown organically without extra fertility; Great uniforms, cut three times during the season.


Too short (3); Variable, timing and stem height on first stem – Long term may not matter much; Only few bloomed – didn’t do well in heat (Zone 8a); Not much vegetative canopy made for lots of weeds to be removed – Lower flowers dropped very early; I never got any flower stems worth writing about – I think the late start due to the wet spring and not being able to get into the field set these back – The only flowers were on 12 inch stems, very pale lavender color, sort of washed out looking; Not productive enough, all our other delphinium did better than these; Nothing this year, some plants survived the heat and should bloom next year.


Looks just like the purple in the Round Table series – ‘King Arthur’; Season is too short in N.H. – For many, cool annual crop – When the land is workable, its too hot; Seed is expensive; My favorite of the trials this year – Can’t wait to plant other colors next year; Would like to try these again on a hopefully better weather year; I thought it was short and was not overly impressive as delphinium go – It did last over a week cut in plain water.
