Lately, i saw a friend has this red one and the butterflies are alighting, nectaring on them. So i asked for seeds which she sent November of last year. I immediately planted them, that to my surprise they flowered immediately when they are just about less than a foot tall. Their life cycle was too short because they die after flowering. I gathered all the seeds and stored them until this years rainy season again.
To my surprise not even one seed germinated. Probably, they belong to the recalcitrant seeds that must immediately be planted upon maturity. Fortunately, there is already this seedling which was already growing when i planted the seeds. This dropped to the soil last year but got stored in the soil and germinated after a few months. I wonder why that is possible! That remains to be a question to me till now.
We can see that the plant is already very tall even prior to flowering. It is more than 6 ft tall. I searched and found that it is a very well studied plant. It is photoperiodic and the internodes elongate much as a response to long days. No wonder my seedlings last year were very short at flowering because they are planted already during the short days. Hmmm, now i can manipulate that height next time, by choosing the photoperiod desired to attain an intended internode length. That would be interesting.
So i just content myself in taking different angles of the flowers, the back against a lot of bokeh as above....
...the side angle with the pollens showing...
...or the top with the petals slightly angling upwards!
I am a bit disappointed that butterflies are not nectaring on them. But still i will again plant those seeds to have a patch with more flowers to invite the butterflies. Next time i have many results to observe, many parameters to test. That makes the unexciting more exciting, don't you think so! Let us all see the next generation of red cosmos with moderate stands, lots of flowers on a single patch, shorter internodes and with lots of butterflies....See you next time around.
Could it be that certain butterflies are attracted on specific flower colors, and that the ones that are partial to that color haven't yet emerged?
ReplyDeleteMaybe yes, but in Bago City Rom's garden a lot of same butterfly species in my garden converge on her cosmos. I still have not come accross literatures yet about this issue, only saw the effects of photoperiodism. Thanks for dropping by and commenting. My former commenters were gone because I have not been regular with my posts.
DeleteMaybe someone should do a study on the relationship between flower color and the species of butterflies they attract, then? Possibly even just a simple list. This I find to be quite interesting.
ReplyDeleteI guess it might already have a study because ir is a basic question. It is just that i am not searching. But the color effect can still be affected by envt'l factors affecting nectar. So it becomes not simple.
