'Early Bird Gold'
Black-Eyed Susan
zones
|
| Description: A
genetic breakthrough in Rudbeckia! This new variety has the incredible
advantage of being day length neutral (not dependent on day length to induce
flowering) which means that it starts blooming much earlier and continues to
bloom later into the season. 'Early Bird Gold' was discovered in a field of
'Goldsturm' at Dupont Nursery in Louisiana where it bloomed consistently two
months before 'Goldsturm' and continued to bloom two months longer as
well. It exhibits all of the other notable qualities of 'Goldsturm'
including golden yellow, daisy-like flowers with a brown cone and a sturdy,
upright habit. |
