Breeder's notes:
This seedling is a much sturdier and healthier plant than its seed parent. Very upright habit with thick stems and glossy, bulletproof foliage. In cooler weather the flowers open with a blush pink but age to pure white. In warmer weather the blooms open white and stay clean with no speckling or freckling. It has also proven to be a good seed parent and passes along its strong disease resistance.
Patents:
Patent status unknown (to HelpMeFind).
Notes:
The pollen for this seedling came from a mixture of some of my best hulthemia seedlings from 2015. This seedling clearly did not inherit any of the hulthemia blotch but did get hybrid vigor. Much taller and stronger than its seed parent Grace Seward.
