"The Easter cactus (Rhipsalidopsis gaertneri) is an epiphytic cactus native to the rainforests of Brazil. It grows on trees and rocks rather than in desert soil, which is why it prefers humidity and indirect light. Its flowers are star‑shaped and come in red, pink, orange, peach, lavender, or white.

Key traits:
Rounded, smooth stem edges (unlike the toothed edges of Christmas/Thanksgiving cacti)
Bloom time: early–late spring

One of the big three types of holiday cactus, the Easter cactus is the most sensitive to care lapses, which is perhaps why it is the least common. This group of houseplants is a little more challenging than Christmas cactus care and Thanksgiving cactus care." Garden Know How.com

Thor Anett comes from the Thor® series, a breeding program by Thoruplund A/S in Denmark—one of the world’s major producers of holiday cacti.
The Thor line is known for:

Consistent flowering
Predictable bloom timing
Strong, saturated colors
Compact, symmetrical growth

Color: Intense red, leaning toward carmine
Shape: Narrow, pointed petals that flare outward
Texture: Slightly glossy petals
Bud color: Deep carmine, sharply tapered
Blooming habit: Heavy bloomer with multiple flowers per segment tip

The pointed petals give it a starburst look—more dramatic than the rounder forms in older Easter cactus hybrids.
