Dendrobium himezakura sanokku
I just picked up a specimen of this, and another nobile type
dendrobium; and have some questions. Do these produce keikis? On the himezura, on the old cane, there are two new growths, that are clearly not inflorescences, coming out of two of the nodes. The very tips of these growths look like nascent leaves. Am I right in guessing that these are keikis? At present, they are each about 2 cm in length. I am happy with this specimen because, even though there are only two canes, and only the larger of the two has leaves, there are inflorescences growing out of each of more than a dozen nodes, and there are plenty of leaves on the younger cane. The other doesn't have nearly as many inflorescences developing, but it has two new canes, and all but the oldest of the canes have plenty of leaves. How do the cultural requirements for nobile dendrobiums compare with those for PODs? (think acronym: POD = plain ol' dendrobium :-), if it isn't too obscene to refer to an orchid as plain :-) ) Will they like a south facing window in the frigid north? :-) Also, I notice on the tag for hamezakura that it is patented by some company in Hawaii. I didn't know there was such a thing as patents on species or races of plants. What is your take on patenting living things? Cheers, Ted |

Cheers, Ted Himezakura is a Yamamoto hybrid nobile dendrobium, and several of these have been patented. All dendrobiums will make keikis, but when one sees many on nobiles it is due to too much N, or not enough sunlight. One parent of this grex was Cassiope, made with Oberon, in 1995, which was made using moniliforme, back in 1890, so this alters the cultural requirements considerably, making it a nobile type, but not demanding the intense cold and drying in the fall and winter of the standard nobile. This is in keeping with Yamamoto's efforts in recent years to develope nobile types which are smaller and more adaptable to growing conditions. |

Himezakura is a Yamamoto hybrid nobile dendrobium, and several of these have
been patented. All dendrobiums will make keikis, but when one sees many on nobiles it is due to too much N, or not enough sunlight.

This is in keeping with Yamamoto's efforts in recent years to develope nobile types which are smaller and more adaptable to growing conditions. I went back (because I noticed when I got it home that it had no tag) and found out that the other one I had bought is also a Yamamoto hybrid called spring dreams 'Apollon': there were several other specimens of this there, properly labelled, but in relatively poor shape. I would assume that this has rather similar requirements to Himezakura. Now, when you say that it doesn't demand an intense cold, dry period, do you mean that its deciduous habit is facultative, and that if I keep it warm and keep watering at the normal rate it will keep going, but if I let it experience a cool dry period it will display the deciduous habit; like the deciduous phals? Or would I end up killing it if I let it see a cool, dry period. How do you think it would fair in a south window in southern Ontario? Cheers, Ted |

Cheers, Ted I personally manage all of these like standard nobiles, however, the big advantage for them is that if they have a drop in temperature in the fall that they then can be placed in a warm, int, or cool room and they will flower. Moreover, they can be watered during this period. They will still lose their leaves like any nobile, either before, during, or shortly after flowering. |

Cheers, Ted These are deciduous plants and will lose their leaves regardless of how you grow them. Flowering is probably initiated by the drop in temperature. Flowering occurs on two year old growth, which is after maturity, and frequently will rebloom the third year. Yamamoto will grow these to maturity and obtain flowers on one year old growth-but, this is done by growing at sea level in Hawaii to maturity and then transporting to the mountains for a drop in temperature and getting flowers on the first year's growth. This does not occur in nature and you will not be able to do it in Canada. You can easily check this on Yamamoto imports as the flowers are on current years growth. You will do better if you put the plants outdoors in full sun for spring, summer, and fall, and then bring inside to that south facing window with SUNSHINE for winter. |

When do they put out new canes, and is there anything that canbe done to stimulate the production of new canes? I ask because the himezakura doesn't have a new cane. Rather, it has three older canes, the youngest having bloomed at least once before, but is covered in inflorescences. The second youngest has only a couple leaves and two keikis, and the oldest, scarely more than 1 cm long, has nothing on it. The spring dream, though, has two clearly new canes that are actively growing and apparently have never bloomed (and neither has any inflorescences), and one middle aged cane that has a decent number of inflorescences, and two old canes that have nothing on them (although one might have had but had recently been broken off at a height of about 3 cm). And on this one too, the oldest canes is scarcely more than 1 cm long. Thanks, Ted |

In a well grown plant, a flowering cane will frequently bloom a second time, the next season, but not as well as the first time. New growth comes from mature canes that are flowering or have recently flowered, and will flower in the second year. Canes which grew this year will bloom next year. |
