Growing Rainbow Elephant Bush Indoors

Rainbow Elephant Bush is usually grown indoors since it can grow laterally and hence take up a lot of space. They are best as a potted plant and should not be grown in a garden where they can reach great heights.

Since the plant thrives in the sun, they require a lot of sunlight to grow. If you’re growing the plant indoors, make sure that you place it close to a window where it can receive maximum light.

This plant needs over 5 hours of sunlight to grow properly, making sure that it can get the required time. If you live in a place without much sunlight, you will need to invest in a grow light. A grow light will also be helpful during the winter months, where the daylight may not be enough for your plant.

Since Rainbow Elephant Bush loves sunlight, they can be placed in areas with full sun or even in places with partial sunlight. They may require acclimatization to full sun if they haven’t learned to tolerate it, and may even get sunburned.

If the plant is not used to receiving full sunlight, you will need to gradually increase the amount it needs, day by day, before you can place it outside. In case there is a heatwave, you will need to protect your plant with sunshades so that it does not get sunburned.

Since this plant likes warm weather, it does not do well in freezing temperatures. It may tolerate mild frost, but it will need to be brought indoors if you live in an area with rough winters. You can also use a frost cloth if you intend to keep the plant outdoors.
