The Differences Between Hippeastrum and Amaryllis belladonna
When strolling through the flower market, have you ever been attracted to two similar red flowers but found it difficult to distinguish between them? As twin sisters of the Amaryllidaceae family, Hippeastrum and Amaryllis belladonna often cause confusion. This article will unveil the mystery of these "red beauties" by comparing their botanical characteristics and growth habits.
Differences in Botanical Classification
Genetic Code of Genera
Hippeastrum belongs to the Hippeastrum genus, with a chromosome composition of 2n=22, including over 30 species such as Dutch Hippeastrum and White-ribbed Hippeastrum. Amaryllis belladonna, on the other hand, is a representative species of the Amaryllis genus, with the same chromosome number 2n=22, but the difference in gene sequences places it in a different lineage.
Mystery of Naming Origin
Due to the evolution of the early plant classification system, these two plants once shared the name "Hippeastrum." Modern taxonomy, through DNA sequencing technology, has confirmed that Amaryllis belladonna is a typical species of the Amaryllis genus, with an oval bulb and a distinct neck, which is fundamentally different from the spherical bulbs of the Hippeastrum genus.
Key Points for Identifying Flower Forms
Code of Number of Inflorescences
Hippeastrum flower stems usually bear 2-3 trumpet-shaped flowers, with the largest flower diameter reaching 25 cm, presenting a "double stars embracing the moon" form. Amaryllis belladonna flower stems often hold up 4-6 bell-shaped flowers, forming a unique "umbel inflorescence," making this numerical difference the most直观 identifier.
The Differences Between Hippeastrum and Amaryllis belladonna
Mystery of Flower Color and Structure
Hippeastrum flowers are rich in color like blazing flames, commonly seen in bright red and crimson hues, with visible white gradients at the base of the petals. Amaryllis belladonna, on the other hand, presents pink to magenta color tones, with the unique scale structure in the throat serving as its "identity seal," which can produce a starry effect under sunlight refraction.
Rhythm of Flowering Sequence
Hippeastrum blooms mainly from April to June, while Amaryllis belladonna has the characteristic of "double flowering." After starting to flower in spring, proper care can lead to a second blooming in late autumn. This difference in flowering periods provides more possibilities for gardening combinations.
By comparing over 20 details such as bulb shape, flower stem characteristics, petal texture, we can clearly identify these red sprites. Mastering these identification skills can not only enhance horticultural appreciation but also allow for scientific care based on growth characteristics, enabling these two "red miracles" to bloom with unique charm in the courtyard.
