Dieffenbachia amoena Common name(s): Dumb cane
Dieffenbachia Genus of about 30 species of evergreen perennials from tropical forest in North and South America and the West Indies. Most cultivars are derived from Dieffenbachia seguina. A well-grown dieffenbachia may reach 5 ft. or more, but under ordinary room conditions some of the lower leaves will fall to give a False Palm effect. It is an easy-to grow plant. Keep away from draughts. All parts may cause mild stomach upset if ingested, and contact with the sap may irritate skin.
Growing conditions Watering and misting Propagation
Average or above average warnth - minimum 60F in winter. Mist frequently. Partial shade in summer - bright light in winter. Water regularly from spring to autumn. Water sparingly in winter. Grow in soil-based potting mix. There are several methods. Remove and pot up top crown of leaves - use a rooting hormone and provide bottom heat. Pieces of stem, 2-3 in. long, can be used as cane cuttings: lay flat on the surface of the soil mix. Some varietis produce daughter plants at the base - remove and use as cuttings.

these are the easiest plants in the world. I started with one stringy plant and cut it down and put the stems in water. Now i have about 7 pots full and growing. Great plant for someone that thinks they cant keep plants alive like me.

I have grown these plants for years. My one tree is seven feet tall with leaves bigger than dinner plates! These trees also do get flowers (nothing special). You can grow these trees with no soil, just make sure if you're using a clear glass container the water will get dirty more quickly. Also make sure you have rocks or gravel in the container to anchor the roots and keep the container from tipping. Easiest plant to grow.

I've had dumb canes for over 30 years, but tonight I noticed what appears to be a type of flower on one, first time I've ever had one flower. Came online looking for a picture of one flowering, couldn't find one but did find this site. 30 years and I didn't know they bloomed... learn something new everyday I guess, LOL! And I must finally be doing something right - but then, they've never had trouble reaching 6-8ft tall so I couldn't have been too far off in their care. My current one is a Camilla (from what I've found online tonight) - the others have all had the dark green leaves with the yellow/green centers (don't know what they were called) and this one is yellow/green with dark green edges.

We have had Dieffenbachia's for 30 plus years also. have had one flower MANY years ago and none since this past week or so. There is at least three flowers and it looks like a fourth onne comming. It seems that they only stay open for a day or so. COOL.

I have a dieffenbachia that has reached 12 ft. twice. First time it was curled over on our 12 ft ceiling. I cut it off and it came up with several sprouts and is now hitting our ceiling again. I started new plants from the cut off portion and grow them in the shade outside in the summer, bringing them in in the winter.

We started harvesting the plant from one ten foot mother plant. It broke in two while moving and we tossed it in the snow. Rethinking our move, we brought one piece in and placed it in water for the winter in the basement. We now have seven huge ten to twelve foot plants all from that one cutting . All have plenty of light and each gets approx one litre of water every two days. They are beautiful, easy and low maintenance. Love them . Who needs furniture or wall hangings
