Solomon's Seal thrives in and out of the ground. Florists love this plant because it lasts a long time in water, but gardeners go for it because it tolerates dry soil once established and sprouts dainty white flowers in the spring. All images courtesy of Norfolk Botanical Garden
Coral (Stichodactyla haddoni, Ukwiał dywanowy) - These Carpet Anemones are my favorites. Clown fish will love them too. Word of caution if your clown fish was breed/raised in captivity it most likely will not know / use an enemone for a home.
