A cultivar from Japan Haworthia cooperi ‘OB1’ has large translucent green window and makes an excellent indoor plant. Like many of the Haworthias, a number of cooper varieties are available and all are easy care houseplants.
In Japan, Haworthia are known as Crystal Plants, this comes from the transluscent windows that shine like crystal when held to the light.
A little debate about the name, should it be H. cooperi OB1 or maybe it should be Obi-Wan. Whatever the name, this truely is a beautiful succulent.
Care and growing Conditions
- This is a plant that grows well in shade, around 60 – 70% shade is ideal. For best appearance of the green leaves the plant needs to kept out of direct sun. In hot sun the leaves can quickly turn brown.
- A very free draining potting mix is essential. A normal cactus and succulent potting mix with around 30% extra drainage material added is suitable. You can add crushed scoria, pumice or perlite to help achieve good drainage.
- Watering should only be carried out when the growing medium is dry. In winter around every 3 – 4 weeks, at others times once a week to every two weeks depending on heat and growing medium.
Re potting
This is a plant that puts out offsets or ‘pups’ and will need to repotted every 2 – 3 years.
Choose a reasonable deep pot as H. cooperi types have largish root systems. Ensure the pot has good drainage holes.
