The largest of all dahlias, this Mexican giant can grow up to 5-8m tall! Enormous, dense clusters of large, golden-centred, pinkish-mauve flowers open on the strong, bamboo-like stems. The foliage often has a purplish tinge. Budding and flowering occur in late summer. An unbeatable architectural plant for a warm exotic border or a large container in a greenhouse or tall conservatory. It is a tuberous, herbaceous perennial, rapidly growing in springtime from its tuber, after a dormant winter period (which may be brief in mild climates).
