Dracaena marginata ‘Dragon tree’
Grow best in bright light, but low light tolerant. Plants in lower light will grow slower and will produce smaller leaves with less intense color. The lower leaves gradually fall away to reveal a thin trunk, so don’t worry.
Allow the top half of the soil to dry between waterings, of course that will vary from household to household. Check the soil, vs setting a schedule when to water. That goes for all plants really.
Toxic to pets, every plant is unique; the one you get may vary from the one in the photo.
