Colocasia ‘Pink China’

Colocasia ‘Pink China’ is one of the hardiest elephant ears around. It is reportedly hardy to zone 6 and possibly zone 5. My ‘Pink China’ has only been through 1 winter and had only seen winter temperatures down to 2f, which is a low zone 7.

My Colocasia ‘Pink China’ grew to about 4-5ft, but can grow larger. Out of all the Colocasias that I grow, both hardy and non-hardy, ‘Pink China’ is the thirstiest. It seems to need water daily if temperatures are in the upper-80’s or hotter, but can make it every other day with lower temperatures. The stems that hold the leaves up is where this Colocasia gets its name from; the stem are pink. The stems are more pink depending on how much sunlight the plant gets. I have also noticed that this Colocasia likes to run with both below and above ground runners. I have it against a fence and it even began growing into the neighbours yard last summer.

    What sort of winter treatment do these colocasias need to survive. I am near Lancaster, PA with similar weather as lexington, KY.

      Hello! I have not grown them until this past spring so I have yet to see if they return. They should return because they are rated to zone 6 and the guy that developed them or discovered them has had them for the past 8 or 9 years lives in Louisville, KY and they have returned for him all those years. Louisville is only 70 miles to the west/northwest of me.

      My orginal plan was to just cut them down and then mulch over them once the first killing frost got them. What I did was cut them down and I covered them with my Musa Basjoo leaves that I had left over from cutting it down. Mulch should be sufficient I believe. This winter they have seen 2f twice and the other day when I felt them they were still solid in the ground so that means they are alive.

      If you have anymore questions then please let me know. I will be posting more in the future as stuff reappears or doesn’t. Thank you for reading my blog and come back.
