You are really a lover of plants and you took the photos patiently waiting for fourteen long years.Please send me the photo of the flower so that it is easier for anybody to identify the species. Let me wait for at least a month. Thank you

It would be helpful I you could post pictures here of the actual flowers when they are open; preferably close-ups from the side, and looking into the flower if possible.

Thank you so much John and Vestia. Thanks for letting me know it will flower further ... i wasnt sure if it would open more, or die off. Which brings me to my next question, any idea if the plant will die after flowering ?? I have spent hours researching on the net, but get mixed opinions.

FLOWERING DAY !! No wonder i was confused, didnt even know it flowered, I thought they were seed pods. Photo of my son (6'3") in front of Yucca. Will these help ID ??

Australia,

You are very courteous and as a plant lover I want to answer your questions. Generally the perpetuation of the plant species is through the off shoots.The side shoots will take over and bear flowers when they mature.Yuccas are pollinated by specific insect group which lay their eggs inside the cavity of the ovary.The larvae of Pronuba feed on the young ovules and emerge as adults (Moths).Please observe all these relationship between Yucca Plant and Pronuba yuccasella (Insect). Yucca peninsularis is also known as Hesperoyucca whipplei ssp. eremica Ref:http://plantlust.com/plants/yucca-peninsularis/

Thanks for your response John, I am so happy you are as excited as we are. I hope we have native insects here in Oz which will pollinate the flowers. Also, I have just been taking more photo's and, loaded with your kind info, and have found some side shoots on our 2nd (fallen) Yucca which isnt flowering. I have taken 2 close ups, and a perspective.

Hi Angie,
If your Yucca is still flowering, you might want to try hand pollinating a few flowers, if you can reach them. Since these plants are not native to Australia, pollination is very hit and miss here. Get the yellow dusty pollen from one flower and transfer it to any flowers which have a sticky end at the end of the stigma in the middle of the flower. Sticky stigmas indicate that the flower is ready to accept pollen.

It still may not work as not all plants in this group are self fertile. Sometimes you need more than one plant as many plants can recognize and reject their own pollen. Please note that all of your little offshoots will be genetically identical to the parent plant so they don't count as different in this way, even if they were flowering.

If you already have some pods forming, well and good. Send me a d-mail and I will let you know how to deal with the seeds,

By the way, I still don't think we have adequately established whether these plants are actually Y. peninsularis. The ones in Plant Files look very different ( http://davesgarden.com/guides/pf/go/64860/ ) and quite a bit smaller. Can you tell me where you came across the name originally?

Ciao, KK.
