Elephant Ear 'Fontanesii'

This attractive, black-stemmed elephant’s ear looks great in containers, beds, and borders. Plant black stem elephant’s ears tubers when soil is consistently around 70ºF. Separate offsets in spring or summer. It is relatively easy to grow in the UK during the summer months. During the winter, it is best potted up and kept indoors under glass, keeing it dry and frost-free. Stop watering from mid-October through to Spring to ensure the tubers don't rot

Planting

From Early Spring TO Early Spring

Elephant ears should be planted slightly deeper than they grow as they will push up. During the growing season, Colocasia will continually produce new leaves as the older leaves continually die off.

 

Propogation by seed

From Early Spring TO Early Spring

Colocasia can be propagated by seed or division. If sowing seed, germination should take place within 21 days.

 

Propogation by division

From Late Autumn TO Late Autumn

If propagating by division, you can divide the larger tubers or separate the new plantlets that form at the rhizome tips.
