What other plant parents say
I took this plant the day of my grandmother funeral. These were her favorite plants she had and taking cuttings from her garden to bring back to my home 8 hours away helped me cope. This plant sat in water for a few months, rooted and I planted it into soil. Now there has been times where I thought it was going to die on me but it shows signs of improper care before it starts to die. This plant is my most prized possession.
You may have to move it away from the window at night if it gets frosty. It loves direct sun. But don’t water it during peak sun, the leaves could burn. It is from Madagascar, so make sure the soil matches. Good drainage and a terracotta pot works wonders. I had to bring back mine from the dead.
The plant does not tolerate soaked soil so make sure to prioritize drainage. It produces small, but vibrant and beautiful pink flowers and has done so regularly for me outside of winter time. The flowers and the leaves however are extremely brittle and fragile.
