49 Flowers That Start With R

1. Rafflesia Arnoldii

Rafflesia Arnoldii

The Rafflesia Arnoldii, commonly known as the Corpse Flower, belongs to the fleshy parasitic herbaceous family and genus. It parasitizes the roots, stems, or branches of plants, devoid of chlorophyll.

Its nutrient-absorbing organs have evolved into mycelium-like structures that infiltrate the host’s tissues. Its leaves have either degenerated into scales or disappeared entirely.

The flowers typically grow singularly, though occasionally in a spiky arrangement, exhibiting radial symmetry and are either unisexual or bisexual. The fruit is a berry with tiny seeds encased in a tough coat, equipped with an endosperm.

The Corpse Flower boasts a magnificent and unique appearance, housing the largest known bloom in the scientific community. Its pungent odor, reminiscent of decaying flesh, has earned its reputation as the world’s smelliest flower.

Found in regions from the southeast to the southwest, it thrives in tropical and subtropical areas.

The Corpse Flower is more akin to fungi. Lacking chlorophyll, it doesn’t photosynthesize. To nourish itself, it forms filamentous tissues with vines, drawing moisture and nutrients from them.

Due to extensive deforestation of tropical rainforests driven by human activity and the Corpse Flower’s long life but short blooming period, it is now endangered.

2. Ranunculus Asiaticus

Ranunculus Asiaticus

The Ranunculus Asiaticus, or Asian Buttercup, is a perennial herb from the Ranunculus family. Standing 20-50 centimeters tall, it possesses a spindle-shaped tuberous root with a singular stem or occasional branches.

The base leaves, resembling celery, are long-stalked, while the stem leaves are smaller and nearly stalkless.

Single or multiple flowers bloom at the stem’s peak in red, white, orange, and purple hues, either double or semi-double, during April and May. The name ‘Ranunculus’ originates from Latin, reflecting the plant’s preference for wet habitats.

Native to southwestern Asia, centered around Turkey, and southeastern Europe, the Asian Buttercup thrives in cooler climates, favoring light but also tolerating shade. It fears extreme heat and prefers well-draining sandy soil rich in organic matter.

When potted, it requires sandy soil with excellent permeability and rich fertility. Reproduction methods include dividing its bulb, seeding, and tissue culture propagation.

The Asian Buttercup is poisonous. Touch can lead to inflammation and blistering. It’s not edible as consumption can cause diarrhea and a slow pulse.

3. Rehmannia Glutinosa

Rehmannia Glutinosa

The Rehmannia Glutinosa, commonly known as Chinese Foxglove, is a perennial herb from the Rehmanniaceae family. The fleshy rootstock is yellow when fresh.

The stem has a purplish-red hue, while its leaves are ovate to oblong, green on top and slightly purple or purplish-red underneath, with irregular round or blunt serrated edges.

The flowers either rise or curve, loosely arranged in a racemose inflorescence on the stem top or singularly in leaf axils, blooming from April to July. The fruit, present during the same period, is ovate to oblong.

In Southeast Asian countries, the “Four Major Huai Medicines” are exchanged as precious gifts. Countries like Japan and the UK refer to these as “Hua Medicine.”

Rehmannia can be classified into fresh and dried variants. Historical pharmacopeias and medical records suggest that the fresh variant is superior in hemostasis and fluid production.

The dried Rehmannia has the ability to cool the blood, nourish the yin, and produce fluids. It can be used in natural floral arrangements.

4. Renanthera Coccinea

Renanthera Coccinea

The Renanthera Coccinea, known as Flame Orchid, is an epiphytic herbaceous plant from the Orchidaceae family. Its stem is hard and cylindrical, with tongue-shaped or oblong leaves.

Due to its vibrant fiery hue, which appears as flames from a distance, it’s aptly named the “Flame Orchid.”

The Flame Orchid is native to China and can also be found in countries like Myanmar, Thailand, Laos, and Vietnam.

It thrives in warm, humid conditions and grows well in full or partial sunlight. It’s heat-tolerant, not cold-resistant, and prefers a loose, breathable substrate. Propagation is typically by cuttings.

The entire Flame Orchid plant is used to treat fractures. With its striking red blooms, the potted Flame Orchid serves as an elegant interior decoration.

It can also be epiphytically grown on tree trunks or rocks for ornamental purposes and is a splendid material for cut flowers.
