What customers say
Gardeners highly value the Cosmos for its stunning, sophisticated double white blooms that deliver an architectural garden element. When successful, the vigor and performance as cut flowers are exceptional, fulfilling the cultivar's promise. However, a significant concern involves inconsistent germination rates, causing frustration among users. Additionally, some reports mention issues with seed purity, noting off type blooms like single petals or pink coloration, which detracts from the desired pure white aesthetic. Despite these challenges regarding consistency, the reward of achieving the perfect double white flower makes this a worthwhile investment for those seeking a high-end garden look.
