    Default Den. Adastra

    well, I've gone and bought another orchid that I know nothing about . It's a Den. Adastra (aphyllum x anosmum). It is in spike, the longest cane is about 22 inches long, and it has two others. I can't for the life of me figure out where the buds are going to come from. Does anyone have an orchid like this one? Can you tell me how it is going to flower? Here are a few pics (with my crappy camera, the new one hasn't arrived yet
    Thanks for the help!

    Hi Kitty,

    Adrasta needs a dry winter rest to bloom. As in completely dry. Back in Oct you stop all watering. The leaves will slowly brown and drop, which they're supposed to. Come Feb when a new growth first appears you begin watering, and the buds will form at the bracts where the leaves were. Mine is just starting new growth and tiny bud formation. That's when you resume watering and fertilizing.

    You may be off the cycle for a bloom this year. But try stopping all watering and see if it starts to lose leaves. It's tough to ignore it like that, you reall want to water it, but that's what it wants! I'll post a photo of mine here when I get a chance - don't have time now, though.

    Will do, Kitty! But I might forget. If I don't do it by this weekend, bump this thread and that will remind me!

    awwww. thanks. no real rush. I was just being brassy. I think I might have found a bud on mine today, except that its on a cane that has all the leaves on it. I was under the impression that the buds would develop on a cane that had already dropped its leaves. I'm so confused. It's cocktail hour.

    Hi Kitty,

    Here is the promised picture. Aaron Tester and I each received small keikis last march, but there were two Dends growing in the basket, and the proper parent plant got confused. It's either a Den Adrasta (pierardii x anosmum) or it's Den aphyllum x parishii. I'll know when it blooms. They're all species in the Dendrobium section of the Dendrobium genus, and culture is very similar.

    It has a pendulous growth habit. The new cane grows downward out of the top of the pot. I potted the keiki in late march, and here it is in mid-Nov, just after I started its dry winter rest (half way down the page):
    http://www.rv-orchidworks.com/orchid...en-pods-4.html

    Through the winter it lost its leaves one at a time. But the cane remained green. It resembled a rat tail after a while sorry Molly Taco - yours is nicer! There's still one leaf remaining, indicated by the pink arrow. New growth began the blue arrow just a few weeks ago. That's the signal to resume watering, which I've done. Little nubs are forming at the leaf bracts, and this is where the flowers will form. Green arrows. One looks very bud-like. The other two look hesitant.

    I don't know how many blooms I'll get. But any would be welcome. They'll mean I figured out a Dend, and that's surely a red-letter day as Diane-Thumb will atest! So not an impressive first blooming, but it's a start!

    As for yours, I don't know what a mixed up schedule will do. If the leaves are browning, then I'd suggest trying to "shift" your winter season. Keep the plant dry and colder. When it starts any new growth, resume watering and move it back into normal temps. You might just fake it out!
