| Neutral | On Jul 9, 2016, DawnandGreg from Birmingham, Hi I live in Birmingham England and have purchased these seeds, could anyone advise me when and how and where to plant these seeds please. Thanks in advance. |
| Positive | On May 21, 2016, vossner from East Texas, I've been growing this plant for six years. It has not expanded much, wished it had. I love it. Planted inground, moist area, mostly shade. |

| Positive | On Apr 5, 2010, stella from Raleigh, NC (Zone 7a) wrote: In North Carolina, we can keep this zone 8b plant alive over the winter by covering it with 1' of leaves and stuff during the winter. It does not start growing again until July, but by September it is huge! |
| Positive | On May 12, 2009, WendyKellyBudd from Chico, CA wrote: I bought the tiniest start from an ebay seller last year. Potted it into a 24" pot, placed it under an oak tree where it gets direct morning sun and in the afternoon has bright light, but no direct sun. Summers are hot, and dry here. Also, keep it out of winds so the leaves don't shread. |
| Positive | On Nov 23, 2008, keonikale from Lexington, SC (Zone 8a) wrote: This is one of our favorite colocasia. It grows extremely fast and the leaves get quite large within just a few months. Spath's will bloom in rows of four and produce large seed pods (if pollinated) beneath each spath. Once they burst you can harvest the seeds, which will be in dozens (if not hundreds) of small "pouches." Each pouch holds dozens of tiny tomato sized seeds that can be planted and will sprout within 2-3 weeks. By three months they'll often have 3-4 leaves and be well on their way to becoming adults in another growing season or two. |
| Neutral | On Jan 20, 2006, Suze_ from (Zone 7b) wrote: This huge strain of the giant elephant ear was grown from wild collected seed (PES 1003B) from Kanchanaburi Province, Thailand, in 2003 by former PDN research manager Petra Schmidt. In the wild, the plants reached a massive 9' tall, which is much larger than the clone of C. gigantea that we currently grow. For us, each individual leaf grows in excess of 5' long x 4' wide. Each seedling will differ slightly, but massive plants will be the result. In foliage, the leaves are an attractive glaucous-grey which is typical of this species. From an early age, the plants are adorned with clusters of dramatically large, pleasantly scented, white flowers. |
