Valley Porcupine – Novelty (Novelty Double) Dahlia
Breeder: Geiske (United States, 2011)
Valley Porcupine is a show-stopping "Novelty" variety that looks like something out of a botanical dream. It is famous for its unique Novelty Double (NX) form, featuring narrow, tubular petals that radiate outward like the quills of a porcupine. This architectural texture makes it a favorite for high-end floral designers and gardeners looking for a conversation piece.
Color Profile: A sophisticated light blend (LB). The petals feature a soft creamy-white base (WH2) with delicate lavender-pink (PK23) tips and highlights, giving the bloom a "frosted" or ethereal appearance.
Unique Form: The "Novelty Double" classification means its petals are uniquely quilled and structured, providing a spiky yet delicate texture that stands out in any bouquet.
Bloom Size: Produces medium-sized 4–5" blossoms, offering a striking visual impact without being overly heavy on the stems.
Plant Height: Reaches a reliable 4' tall (48") with a sturdy, upright growth habit and clean, strong stems.
Design Appeal: Because of its neutral but "frosted" color palette, it pairs beautifully with deep purples or soft pastels and is a standout choice for adding structural interest to wedding arrangements.
