Garden plant Libertia grandiflora 

This lovely white flowered evergreen perennial garden plant is a must in any garden. Libertia grandiflora, (New Zealand satin flower) has narrow pointed green leaves and in May June has stiff stems of three petaled white flowers. They will grow in sun or part shade and like a moisture retentive humus rich soil. Having said that as you will hear on the video they are reasonable versatile in their requirements so don't worry too much. Just don't let them dry out in summer. If the clump is getting too big, or you want more plants, divide the clump in spring just as they come into growth. Plant back immediately and keep watered till they settle in again. They will also seed but unless you have patience to wait some time for a plant big enough to flowers just remove the seedlings.
