Philodendron hastatum is a climbing philodendron with silvery blue foliage. The hastate leaves can grow up to 20-30cm in length, and get larger with something to climb.
In Melbourne they make beautiful indoor plants and don't require much care- don't overwater as they can get root rot. Leaves will curl when underwatered.
If grown outside in Melbourne they must be fully protected from frost and sun, preferably under a canopy of other tropicals such as palms and Bird of Paradise (Strelitzia Nicolai).
