Not only was I captivated by Hagley Park’s begonia display but its dahlia border garden, too. The dahlias occupy a small strip along the periphery of the much larger rose garden, a great attraction in itself. The stunning variety represents the hybridizer’s craft. On one end are the single-row specimens from their native Mexico. How they were hybridized into much more complex forms is and will remain a mystery to me. This amazing morphological variation is showcased in the much larger dahlia garden section by flowers developed by New Zealand horticulturists, including the intriguing ‘cactus’ varieties.
