Dianthus ‘Sweet Purple’

Trial: Annual

Year Trialed: 2004

Year of Trial: First (from 2004 report)

Good Qualities:

Nice vibrant color (5); Good fragrance (3); Much more appealing than the Amazon Neon Duo series; Lasted long time in field and in cooler; Long vase life; Mix well in bouquets; Easy, good for bouquets, nice dark foliage, quick to produce; Bloomed 2 weeks earlier than Amazon Neon, this purple is the same color as the Amazon purple; Germinated great; In the tunnel, 2 weeks earlier than Neon series, will produce a second flush of flowers in late Sept through Oct (Zone 5) but stems even shorter then, most productive of the Dianthus in trial; Outside, early, productive, first harvest by June 23, flowers in year of sowing without cold treatment; Could be cut from bud to fully open for immediate use; Easy to grow, multiple stems produced during flowering season.


Too short (3); No problems; Planted too late – I think they would have done much better, if planted in fall; Blister beetles ravaged the flowers, picture is on, Sevin controlled the beetles, had to spray twice in August; In the tunnel, thinner stems than Neon series; Outside, stem length marginal; Stem length inconsistency; Many of the secondary stems are weak.


They were pretty easy to take care of, they do have a tendency to snap at the joints when I was handling them to strip leaves.


Looks like the same genetics as Neon Duo which is good; Outside, this variety is 5.5 inches shorter than Amazon Purple, but 20 days earlier; Good cut flower; The tunnel grown available for July 2 sales; Support wire was necessary; Dianthus barbatus is a biennial B flower production per plant during the first year was very good; however, we have left these plants in the field over winter to determine if they will flower better the second year.
