Jurassic Watermelon Rex Begonia
Basic Information
Common Name: Jurassic Watermelon Rex Begonia
Scientific Name: Begonia ‘Jurassic Watermelon’
Native Habitat: Hybrid, not found in the wild.
History / Discovery / Cultivator
Begonia ‘Jurassic Watermelon’ is a captivating cultivar belonging to the Rex Begonia group, celebrated for their strikingly ornamental foliage. Unlike naturally occurring species, ‘Jurassic Watermelon’ is a hybrid, specifically created for its unique aesthetic appeal. The “Jurassic” series of begonias, including ‘Jurassic Watermelon’, are the result of innovative breeding techniques aimed at enhancing leaf texture, color, and overall vigor. While the specific breeder and precise details of its origin may be difficult to pinpoint due to proprietary information, the Jurassic series is generally credited to the Dümmen Orange breeding company. Dümmen Orange is a globally recognized leader in the breeding and propagation of ornamental plants, known for introducing many popular cultivars to the market.
The Rex Begonia lineage itself traces back to Begonia rex, a species discovered in Assam, India, in the mid-19th century. This discovery sparked intense interest among horticulturalists, leading to extensive hybridization efforts to develop new and exciting varieties. ‘Jurassic Watermelon’ represents a modern continuation of this tradition, combining the desirable traits of various Rex Begonia ancestors.
The name ‘Jurassic’ alludes to the prehistoric appearance of the leaves, with their bold textures and pronounced patterns reminiscent of ancient flora. The ‘Watermelon’ epithet specifically refers to the coloration of the leaves, which exhibit a striking combination of silvery-green, pink, and deep burgundy hues, resembling the rind of a watermelon. This vibrant color palette, combined with the ruffled and spiraled leaf edges characteristic of Rex Begonias, makes ‘Jurassic Watermelon’ a highly sought-after plant among collectors and enthusiasts.
The rise in popularity of ‘Jurassic Watermelon’ can be attributed to its relatively easy care compared to some other Rex Begonias, as well as its dramatic visual impact. It quickly gained traction in the houseplant community, becoming a staple in nurseries and garden centers worldwide. Its unique appearance makes it a focal point in any indoor garden, adding a touch of exotic beauty to any space. Social media platforms have further propelled its popularity, with countless posts showcasing its stunning foliage. The ongoing demand for ‘Jurassic Watermelon’ speaks to the artistry and skill involved in its creation, cementing its place as a significant contribution to the world of ornamental horticulture. Its introduction marked not just the addition of another begonia to the market, but also an advancement in the breeding and development of Begonia cultivars. The careful selection and combination of traits to achieve the striking ‘Jurassic Watermelon’ showcase the dedication of plant breeders to create increasingly captivating and accessible plants for home gardeners and collectors alike.

Botanical Insights
Adaptations
‘Jurassic Watermelon’ Rex Begonia, while a cultivated hybrid, inherits several adaptations from its Begonia rex lineage. These plants, originating from humid, shaded environments, have adapted to maximize light capture and moisture retention. The broad, textured leaves increase the surface area for light absorption in low-light conditions. The colorful variegation may also play a role in attracting pollinators in the wild ancestors or providing some level of sun protection. The rhizomatous growth habit allows the plant to spread and establish itself in suitable environments, while the ability to tolerate relatively high humidity reduces water loss through transpiration. The slight hairiness on the leaves can also help to trap moisture and deter small pests.
Propagation Methods
‘Jurassic Watermelon’ Rex Begonia can be propagated through several methods:
- Leaf Cuttings: This is a common method where a healthy leaf is cut into sections, with each section containing a major vein. These sections are then placed on a moist growing medium, such as peat moss or vermiculite, and covered to maintain humidity until new plantlets form.
- Rhizome Cuttings: Since Rex Begonias are rhizomatous, sections of the rhizome can be cut and planted. Ensure each section has at least one node or growth point.
- Division: Mature plants can be divided at the root ball, ensuring each division has sufficient roots and foliage.
- Stem Cuttings: While less common than leaf cuttings, stem cuttings can be taken from healthy stems and rooted in water or a moist growing medium.
Toxicology
‘Jurassic Watermelon’ Rex Begonia contains soluble calcium oxalates, which are toxic to both humans and pets. If ingested, these oxalates can cause immediate burning and irritation of the mouth, lips, and tongue. Symptoms in humans may include excessive drooling, difficulty swallowing, and vomiting. In pets, such as cats and dogs, ingestion can result in similar symptoms, along with loss of appetite. While severe reactions are rare, it’s best to keep this plant out of reach of children and pets. If ingestion is suspected, rinse the mouth with water and contact a poison control center or veterinarian immediately.
Common Problems
Pests:
- Mealybugs
- Spider Mites
- Aphids
Diseases:
- Powdery Mildew
- Botrytis Blight (Gray Mold)
- Root Rot
Other:
- Leaf Yellowing: Overwatering, poor drainage, or nutrient deficiency.
- Browning Leaf Edges: Low humidity, inconsistent watering, or fertilizer burn.
- Drooping Leaves: Underwatering or extreme temperature fluctuations.
Rarity & Value
Rarity:
While not exceedingly rare, ‘Jurassic Watermelon’ Rex Begonia can be considered moderately rare compared to more common houseplants. This is due to several factors, including the specialized breeding required to produce its unique characteristics and the relatively slower propagation rate compared to some other begonias. Its distinct color patterns and textured foliage make it highly sought after, driving up demand and contributing to its relative scarcity in some markets.
Value:
The value of a ‘Jurassic Watermelon’ Rex Begonia specimen is influenced by several factors. Size and maturity play a significant role, with larger, more established plants commanding higher prices. The intensity and stability of the variegation are also key determinants of value; specimens with vibrant, well-defined watermelon-like patterns are generally more desirable. Overall plant health and condition, including the absence of pests or diseases, are also crucial. Additionally, current collector trends and demand within the houseplant community can significantly impact market value. Plants sourced from reputable nurseries or known collectors may also fetch higher prices.
