Hoya plants, also known as wax plants, are highly sought after by collectors for their unique foliage and striking, often fragrant, star-shaped flowers. Some of the most coveted varieties include Hoya krimson queen, Hoya pubicalyx, and Hoya kerrii, each distinguished by their variegated leaves, lush green appearance, or heart-shaped foliage. These plants thrive in bright, indirect light and prefer well-draining soil, making them relatively easy to care for despite their rarity. Due to their slow growth and specific cultivation needs, acquiring and maintaining rare Hoyas can be a rewarding challenge for home horticulturist.
