Plant care tips: Grass Orchid, Showy Medinilla, Coleus and ZZ Plant

This plant (pictured), which I found discarded, has small flowers that look like orchids. What is it and how do I care for it?

The plant is an orchid botanically known as Eulophia graminea. It has common names such as Grass Orchid and Bawang Hantu. Often, it sprouts from new soil that has been brought in to fill development sites.

The plant is a terrestrial orchid species and prefers to grow in a sunny location with direct sunlight. At home, you can grow it in a pot with well-drained and moisture-retentive soil.
