How to Distinguish Between Euphorbia and Hylocereus
In the care of indoor green plants, many enthusiasts often confuse euphorbia with hylocereus. What are the differences between these two plants with similar appearances? Through the detailed comparison in this article, you will master practical skills to accurately distinguish them.
Plant Attribute Tracing
Family and Genus Differences
Euphorbia (Euphorbia trigona/CROWN OF THORNS) belongs to the Euphorbiaceae family and is a typical succulent plant. Hylocereus (Hylocereus undatus/KING OF THE NIGHT) belongs to the Cactaceae family and the Hylocereus genus, and these two plants have essential differences in botanical classification.
Morphological Feature Comparison
Stem Structure
The succulent stem of euphorbia can reach up to 8 meters high, presenting a distinct three-lobed structure with special small pits in the axils of the ridges. In contrast, the stem of hylocereus is thinner and more branched, with regular aerial roots on the surface and spines spaced about 3-4 centimeters apart.
Flower Identification Points
Flowering Characteristics
Euphorbia flowers are solitary, with 25-30 cm long sepals showing a gradient from yellow-green to white petals that open at night. The funnel-shaped flowers of hylocereus have yellow-green outer petals and white inner petals, resembling typical Cactaceae flowers more closely.
Fruit Morphology Differentiation
Fruit Characteristics
The elliptical fruits of euphorbia (6-12 cm) have a bright red skin and white flesh. The fruits of hylocereus are oblong, usually larger, with more regular scales on the surface.
Cultivation Trait Differences
Growth Habits
Euphorbia is drought-resistant and suitable for sandy soil; hylocereus prefers warm and humid conditions and requires more frequent watering. In winter care, euphorbia needs to remain completely dry, while hylocereus still needs appropriate watering.
Through systematic comparison, it can be found that these two plants have significant differences in multiple dimensions. Mastering key identification points such as stem features and flower shapes can effectively avoid confusion. It is recommended to make comprehensive judgments based on the plant's growing environment and to obtain the most accurate conclusions through flowering observations when in doubt.
