    I would tend to agree with you, but still very nice.

    It does very well between phalaenopsis and cattleya light levels and requires good humidity. I would say it is fairly easy to take care in our conditions. I have been looking to collect all the various color forms and I have few more in spike. One big sized alba variety did not put out a spike and I punished it by hanging it up in the green house to get more light.

    A very lovely variety Sriram; congratulations! I had one so-called 'Blue' but later found out that it was actually a cross between Rhy gigantea and V coerulea. There are also other so-called 'blue' that turned out to be crosses with Rhy coelestis. Could yours be one of these, seeing that the spike is upright?

    You are correct. The spike is erect like Rhy coelestis and It is almost dark purple in color. from what I understand this is a cultivated species where the Rhy gigantea is crossed with Rhy coelestis blue and then the F1 is back crossed with Rhy gigantea for 3 times and the resultant is this form. from what I gather , Once a primary hybrid is back crossed with original parent for 3 times, the resultant generation can be still called the parent species with some additional characteristics inherited from the other parent. I am not sure how true this is and It is still greek and latin to me.

    Thanks Sriram for the info. I am not aware of this fact, but that could explain the upright habit of the spike . Any way it is still a very desirable form. The one I had did have a blue colour like V coerulea but the flower shape was more open like an Aranda and the size of the blooms were bigger than the typical Rhy gigantea. Yours seem to be very Rhy gigantea looking except for the upright spike habit.
    After looking at your gigantea I went out to my orchid house to see if my giganteas were showing any signs of blooming. To my pleasant surprise all were in various stages of spiking. I realize that the blooming season is always a month earlier in your place. I just hope this year's El Niņo doesn't play havoc with the blooming.

    I heard from the news that this year's El Niņo is as strong as or at least comparable to 1997/98's. Expect hot, dry and hazy weather. I'm worried too.
