It forms tidy, symmetrical rosettes of fleshy, triangular leaves tipped with translucent "windows" that filter light down into the plant's interior. The leaves are bright green with subtle striping, and the clumping growth habit means one pot naturally fills out into a full, layered display over time. Star Window Plant stays compact, typically reaching 3-5 inches in diameter per rosette, making it suited to tight shelving and small spaces.
It produces small pale flowers on spikes, typically appearing in spring when conditions are right. A slight nighttime temperature drop in autumn can encourage blooming. It is non-toxic and safe for cats and dogs.
You can leave it up to ten days without water. Move it outside in summer in a sheltered, bright spot, but cover it from rain and bring it indoors before temperatures drop. Propagate it by gently removing the offsets that form around the base of the mother rosette, allowing each offset to callous for a day before planting in fresh succulent mix.

🌵 For Succulents
When your package arrives, you may notice a bit of loose soil in the box. This is completely normal during shipping.
Please remove your plants from their packaging right away and follow the care instructions included with your order. Succulents prefer to dry out between waterings, so only water when the soil is completely dry.
Succulents are resilient plants and typically recover quickly once they settle into their new environment. Give them a few days to adjust before placing them in direct sunlight, and avoid fertilizing right away.
