    Default Cattleya walkeriana alba 'Limerick'AM/AOS

    Cattleya walkeriana ‘Limerick’ AM/AOS has a green flush visible here and there - presumably the basis of Limerick !. A lovely small cattleya that the pic does not do justice to. Needs to be a multi-growth plant with lots of flowers, then would be the sort of show-stopper that Den cuthbertsonii is. But my plant is a seedling flowering for the first time.

    Nice flowers on that plant Geoff! I noticed that the flowering pbulb is not mature yet. Is this a characteristic of walkeriana? I have 2 Catts wich I bought without flowers, and the new pseudobulbs have started to grow flower sheaths, although they are not mature (they kind of look like yours).

    Beautiful flowers.

    I thought C. walkeriana flowers only from the bottom of the bulb and not from the top (sheath)?!?

    There have been some heated discussions about this in the past. From what old orchid systematists tell us, walkeriana should flower only from the bases of the pseudobulbs on special leafless growths not like other catts from the top of pseudobulbs. And most tipo cultivars flower that way. But when it comes to albas some flower from the base while some flower on top of pseudobulbs and from what I have been told even the awarded alba clone 'pendentive' shows variable flowering sometimes from the base and sometimes from the top. Some suggest that the top bloomers are not pure walkerianas but that they have some dolosa alba blood in them so to say. It cannot be cleared out without molecular genetic studies. So just lets enjoy this pure beauty here.

    nope.
    I have found that other species supposed to flower from the rhizome on special flowering growths do so only intermittently ; I recently had another ( different- can't remember which ) species with three spikes ; two from sheaths on top of the bulbs, one from a specialist growth at the base . Subsequently I had three new growths - one of them from the specialist growth.
    My conclusion is that a specialist growth is no such thing. It is simply that with some species, if the plant is sufficiently strong to be able to flower without bothering to make a bulb first it will do so.....It is logical that a seedling flowering for the first time would not be in that category.

    Thank you for all your reasonable explanations.
    I haven't been growing Catts for a long time so there is still a lot to learn! Can't wait ....
