Examples of monocotyledons
Wheat is a type of grass. It has long stems with no secondary growth and leaves that have parallel veins, both hallmarks of the monocot.
Hostas, also known as plantain lillies, are suited to shady parts of a garden. The hosta’s parallel leaf veins make it immediately recognisable as a monocot.
The daffodil belongs to the genus Narcissus. Again, long narrow stems and leaves with parallel veins mark it out as a monocot.
