Dianthus ‘Radiant Purple Eye’

Dianthus 'Radiant Purple Eye'

Trial Started: 2005

Year of Trial: First (from 2005 report)

Good Qualities:

Nice intense color (6); Number of stems; Very fat stem; Great blooms; Fast.


Too short (5); Few were harvested; Not have been a standout; Stems a bit floppy; Lost approximately 25% to a crown rot, plants not vigorous; Color not as intense as other dianthus; Not really distinctive enough, just kind of an also ran except for the quick production time; Plants were short lived after transplant; In general the Radiant series was not as good in the field as the Sweet series – the flowers were smaller and not as well filled, the plants had a less healthy appearance, it shows no frost tolerance.


Heavy rain did not affect plants or blooms; Harvest interval 6/27-7/11; High tunnel crop, transplanted late resulted in short stems; Seeds were planted in 98 (cell) trays and covered lightly with vermiculite, grew slower in cells than ‘Amazon’ – 10 weeks for ‘Radiant’ and 7 weeks for ‘Amazon’ planted at the same time; Short stemmed and short lived; ‘Amazon Neon Duo’ performed much better.
