Vriesias (Latin names: "Vriesia" and "Guzmania") are like urn plants, but they have no spines and their leaves are softer. They are often sold in flower shops (and sometimes in supermarkets) and are very easy to look after. Their flowers grow on a single stem, protected by flattened, colourful leaves. It is better not to fill the central space with water, as these soft-leaved plants might rot. instead their soil should be watered.
