Consolida ‘Stiletta Indigo Blue’

Consolida 'Stiletta Indigo Blue

Larkspur
Trial: Annual

Year Trialed: 20082009

Good Qualities:

Year 1: 

The intense indigo blue color (5), slightly taller than other larkspur in my fields, nice vigorous plants; Tall, attractive, with usable branches after main stem was cut; Good as both a fresh cut and dried flower.

Year 2: 

Attractive blue flower (5); Went well with ‘Rosy Red’; Flowers were nice; The color was unreal – bright, deep, delphinium blue – a color I’ve never found in a larkspur; Many useable branches even at 6 in. spacing; Healthy plants.

Problems:

Year 1: 

None (2); Died in field; Although planted early in May, stems never attained any height, the plugs were not root bound so I don’t know why this happened; Shorter than other larkspur, although we had a very dry spring.

Year 2: 

Too short (2); Germination wasn’t good and didn’t have many plants to work with, liked what I got, but just wasn’t enough to make a good recommendation; Flower stems shorter than ‘Stiletta Rosy Red’; Other larkspur varieties are much better; In the past I’ve had better luck with larkspur, we got it into the field early enough but then we had a month of no sun, rain and unusually cool weather, plants seemed stunted.

Similar Cultivars:

Year 1: 

‘Cannes Deep Blue’; Also grew ‘Sublime’ larkspur mixture of which this cultivar has similar growth characteristics, but not the indigo blue color; Also grow ‘Blue Cloud’ larkspur that has a similar dark blue color, but is more open and airy in appearance.

Year 2: 

‘Stiletta Rosy Red’.

Comments:

Year 1: 

Last year’s (2007) larkspur cultivar was a much better performer; I would like to try this again under normal spring conditions, this larkspur did very well compared to other larkspur cultivars I grow, generally do not do well with larkspur but the past two years I have had good success including variety trial cultivars, I think this one will be a winner.

Year 2: 

No yield, plants dwarfed by plug tray, wet spring; Although my customers loved the ‘Rosy Red’, I think the blue was their favorite, but we sold all of both, so they are both worth having; I tried a new compost mix which was too heavy with manure and destroyed all of the seedlings of these plants, I won’t make that mistake again!; My wholesaler and florists went crazy over the color. It was a huge hit!; Cut the whole plant; Cornell trial yield: pinching early yielded 6 stems/plant, 22 in. long, delayed 3 days in harvest compared to the unpinched plants, tunnel-grown: 31 inch main stem, 20-inch branches.
