Golden arum lily is a tuberous, bulb-growing ornamental with deep green leaves spotted white and yellow summer flowers, grown mainly in gardens. Its native status is doubtful and it may be a garden hybrid, so care in cultivation is the key focus.

About
Zantedeschia elliottiana, golden arum or golden calla lily, yellow calla lily, is an ornamental herbaceous plant in the family Araceae. It grows from a bulb. It is said to occur in the province of Mpumalanga in South Africa, although other sources say that it is not found in the wild but appears to be a hybrid of garden origin.
How to grow it
It (or its cultivar(s)) is a recipient of the Royal Horticultural Society's Award of Garden Merit. It has been shown that, as with other members of the family Araceae, immersing Zantedeschia elliottiana bulbs in gibberellic acid (GA3) solution and planting them at the end of February increases the emergence rate and the number of emerging shoots.
