Last Updated on December 24, 2022 by Clarisse Walters

Is There a Plant Called Ruby?

Ruby plants do exist. The Roof Houseleek (Sempervivum tectorum), also referred to as ‘Hens and Chicks’ or simply houseleek, is an example of a Ruby plant. It is a succulent ruby plant that produces beautiful red or mauve-pink flowers.

These Ruby plants can grow as tall as 6 inches and spread up to twelve inches. It will thrive well in well-drained sandy soil with a neutral pH of 6.6 to 7.5. 

They also grow well in full sun but will need partial shade in extreme heat, especially the afternoon sun. If roof houseleek is grown in the late spring and the right conditions are present, it will bloom in summer. 

Little Ruby Plant

Joseph’s coat (Alternanthera dentata), also called the little ruby plant, is an excellent ground cover with a great compact, spreading behavior.

 It is an ideal cover plant because it grows 10 to 12 inches tall and spreads between 14 to 16 inches. It would be best to space it 10 to 12 inches apart if you want a dense area cover. Alternanthera dentata grow well in moist, well-drained soil rich in organic matter and with a neutral pH of 6.6 to 7.3.

In addition, the plant requires partial shade to full sun exposure for best performance. Foliage becomes more intense in full sun throughout the day. Grow little ruby in early spring to evade the danger of frost. 

How Do You Take Care of a Little Ruby Plant?

To get the best out of the little ruby plant, you must provide all the requirements and maintain them properly. Consider this care guide.

Feeding and watering

The plant requires daily watering in the first few weeks of growing. Adjust the watering schedule depending on the weather and soil type; clay soil needs less water than sandy soils. Alternanthera dentata does not require extra fertilizer besides the organic matter in the soil as too much plant feed will kill the plant. 

Transplanting and soil 

The little ruby plant will grow in almost all soil types as long as it drains well. If you need to boost the soil drainage before transplanting, add organic matter like peat moss, manure, or garden compost. 


Alternanthera dentata is a low-maintenance plant as long as it grows in full sunlight and well-draining soil. It is best to grow it after the last phase of frost. When necessary, pruning the plant will help maintain its compact size.

Ensure that it stands in full sun and water appropriately throughout its growing period in a greenhouse. Water sparingly during winter and pitch the tips to remain neat and appear formal. 

It would help to know that you can grow joseph’s coat indoors in a container. If this is the case, ensure you place it in good ventilation and water scarcely in winter, increasing water during dry and hot seasons.
