Visitors to this page have left the following comments| Lori Skulski | Jun 22, 2008 | I think the leaves on this plant suggest that it is Incarvillea delavayi rather than I. mairei, which has simple, more-or-less ovate leaves.
Sure looks like you're right, Lori - thanks. I've shuffled my pages around accordingly. |
| Ruby | Aug 09, 2010 | Hi
I wintered an incarvillea delevayi last autumn, althought it resumed growth this year, was planted too late last year to show seed pods. So, this spring i bought 10 of them. To Winter in Calgary, Alberta is an accomplishment as they are rare and need mulch and barely tolerate our winter, but i succeeded and they are rare and expensive in our nurseries. They have bloomed, established and grew these long stems with lots of fat full seed pods. I didnt know what they were at first, be read that they are seed pods and when they begin to brown they will burst and sow seeds. Of course, i dont want a million more free seeding in my garden, but i realize these are precious, rare and expensive nursury plants. I have harvested my seeds and am not sure if i can sell them to suppliers or grow them all and sell new babies to nurseries. 1) do you know if i can do either of these and if they would be interested? I have couple thousand seeds so dont want to waste them 2) most of the seeds inside each pod are brown to dark brown and a bit grey after drying,,,,,although some of the seeds are still green. I couldnt risk green seeds exploding and sowing so i harvested them anyway. Do you know if green seeds will still grow and are sellable? 3) do you know roughly how many of these seeds are in each pod? i realize all pods are different sizes, but just roughly,,,,they are so small to count, but if you know then saves me counting lol.
Please let me know. I cant find anything on any website that will answer the greed seed question.
thanks
Ruby
The seeds for incarvillea are not tiny - they are flat discs, maybe 1/4-3/8" in diameter. Are you sure you have thousands of these? I don't know at what stage of ripeness they attain viability - only way to tell is to try to germinate them. They aren't difficult to germinate, so I would certainly do so. I've not grown plants for the wholesale market, so I can't give advice on your plans to do that. |
| Sandra | May 22, 2020 | My comments are addressed to Ruby of Calgary. I am absolutely amazed you got them to overwinter here in Calgary Alberta given our climate. I am curious if you ever were able to propagate them other than by seed? |

- Seed from NARGS '19/'20 exchange. Baggy 70F (38%G, 4d)
