Hoya plants are popular for indoor gardening, known for their waxy foliage. Among many varieties, ‘Krimson Princess’ and ‘Krimson Queen’ cultivars of Hoya carnosa are admired for their striking variegation. They are often confused due to similar appearances, so this article clarifies their differences.
Key Distinctions: Variegation and Growth
The most apparent difference between Hoya ‘Krimson Princess’ and ‘Krimson Queen’ lies in the pattern of their leaf variegation. Hoya ‘Krimson Princess’ has green leaf margins with creamy white or pink variegation in the center. This central variegation can show pink hues, especially on new growth or in bright, indirect light. Its leaves are shorter and thicker, feeling succulent-like.
In contrast, Hoya ‘Krimson Queen’ has green leaf centers with creamy white or pink variegation along the outer edges. New growth can emerge pink, fading to white or cream as leaves mature. ‘Krimson Queen’ typically has longer, thinner leaves. Both are vining plants, but ‘Krimson Queen’ can have a more vigorous vining habit.
Shared Care Essentials
Despite their distinct variegation patterns, both Hoya ‘Krimson Princess’ and ‘Krimson Queen’ share similar care requirements as cultivars of Hoya carnosa. Both thrive in bright, indirect light, which maintains vibrant variegation and encourages blooms. Direct sunlight can scorch leaves, while insufficient light may fade variegation and reduce growth.
Both prefer well-draining soil mixes. Water when the top inch or two of soil feels dry; overwatering causes root rot. As semi-succulents, they store water in their leaves. Average room temperatures, typically between 60°F and 85°F (15°C – 29°C), are suitable, and they appreciate higher humidity. Fertilize with a balanced, diluted liquid fertilizer during the growing season to support health and encourage flowering.
Why the Confusion? And How to Be Sure
Confusion between ‘Krimson Princess’ and ‘Krimson Queen’ stems from their shared Hoya carnosa lineage and similar variegation color. Both can display pink tones, especially on new foliage or under optimal light, making initial identification challenging. Young plants may also have less pronounced variegation. Their star-shaped, fragrant flowers are similar in color (white to pink with red centers), so blooms are not a reliable distinguishing feature.
The most reliable identification method is observing variegation placement on mature leaves. For ‘Krimson Princess’, variegated sections are on the inside of the leaf, surrounded by green edges. Conversely, ‘Krimson Queen’ has variegation along the outside edges, framing a green center. Examining several mature leaves helps confirm the pattern and ensures accurate identification.
