Gloriosa

The Gloriosa dahlia is unapologetically bold. Brilliant golden-yellow petals are splashed, streaked, and brushed with vivid red to reddish-orange, giving each bloom a fiery, hand-painted appearance. No two flowers are exactly alike, making her a standout for gardeners who love saturated color, dramatic variegation, and flowers that refuse to blend quietly into the background.

📖 From the journal of Hedge & Alchemy

This one arrived in my garden labeled Lady Darlene, but she very clearly had other plans! Longfield Gardens also carries Cambridge, so that became my first suspicion when she bloomed. After comparing the flowers more closely, her coloring, patterning, and overall appearance look much more like Gloriosa. I’m growing her under that name while I continue watching future blooms for confirmation.

What I can say with confidence is that she is an exceptionally vigorous plant. I grew two plants, both tall, strong, and remarkably abundant, producing lots of growth and flowers throughout the season.

🌸 In the Garden

• Bloom: Approximately 6 to 8 inches, with brilliant yellow petals irregularly streaked and splashed with red to reddish-orange. The pattern varies noticeably from bloom to bloom.

• Plant Height & Habit: Tall, strong, and vigorous. Both plants at Hedge & Alchemy developed into substantial, upright plants with abundant branching and flowering.

• Growing Notes: A highly productive choice for gardeners who prefer bold, saturated color. Her strength and vigor made her one of the more substantial plants in the patch.

• Tuber Yield: Excellent so far. Both of my original plants began from sizeable multi-tuber clumps and showed the kind of vigorous growth that suggests she should be a strong tuber producer.
