Variety description

10 August 2026

The variety forms large flowers of a rich purple-crimson color. The leaves are deep green in shade, heart-shaped with a narrow long tip; in autumn, they can acquire an amber-orange color with red veins. The stems and peduncles also have a reddish tint.

The plant is a frost-hardy perennial, annually forming new shoots about 1 meter tall. Flowering begins in August and continues until September or October. The hibiscus prefers a sunny location and requires regular watering to maintain constant soil moisture; additionally, it may need support due to the weight of the shoots.
