Hildewintera Hybrid 'Traisenkönig' — Rare 4"+ Golden-Yellow & Bronze Blooming Cactus

'Traisenkönig' — "King of the Traisen" — is a regal Hildewintera hybrid that lives up to its royal name. Hybridized by Dr. Irmfried Buchmann (Hyb. #BUM 2300-1), a cross of HWH 'Butterfly' x Helianthocereus huascha var. (Yellow), it produces 4"+ blooms in a deep, bright golden-yellow with three rows of short, wide, overlapping inner petals, longer narrow outer petals with bronze-tipped edges, and recurving bronze-gold back petals. The cream-to-light-yellow stamens and greenish throat complete a bloom that's warm, luminous, and unmistakably majestic.

This well-rooted plant is 6–7 inches tall with 2.5" diameter multi-ribbed cylindrical stems and long brownish spines — a strong grower with columnar form that can become pendant as stems lengthen.
