Aš Phalaenopsius jau gal porą savaičių kaip išnešusi laukan. Nuo saulės atokiai, po stalu. Bet taip patiko tas temperatūrų svyravimas, kad žiedstiebius leisti pradėjo. <...> Vieną maximinį, vieną cornu-cervi, ir dar kažkokių porą rūšinių.

Kalbant apie falenopsius tai visus dar gegužės mėn gale išnešiau, tai tikrai pasijautė augimas, net kai naktys vėsesnės buvo, pasimatė augimas bei keli žiedynstiebiai. Labai džiaugiuosi Phalaenopsis sanderiana sumastė žydėti. Tik aš juos ne lauke laikau, o šiltnamyje kur visą parą atidarytas langas ir durys, tiesiog gaunasi stogas virš galvos augalams, kad nelytų.

estación seca wrote:Most Phals sold are in one of two groups.

Those with flowers very round in outline, usually with a base color of white to pink, trace ancestry to species like Phal. amabilis, aphrodite, schilleriana, stuartiana. Parent species typically lack bars or spots, but hybrids have been developed to have spots. Most are not fragrant; a few with schilleriana ancestry are. Leaves tend to be dark to very dark green, sometimes with silver spotting and streaking, and sometimes with reddish tones under the leaf. Leaves have a dull matte finish or may be shiny. They tend to make flower spikes in winter. There are usually many flowers, eventually all open at the same time. Spikes tend to make a certain number of flowers in one year, then die. Sometimes a spike with bracts near the base may make another branch with flowers in future years, but this is not routine. This group comprises most of the hybrids sold en masse in markets. They prefer warm temperatures for best growth, but tolerate typical home temperatures. If you are comfortable in a home wearing a short-sleeved shirt and short pants they will be fine. If you need more clothing to keep from shivering the plants will feel chilled. These also do pretty well in the humidity of most homes. These may survive if you forget them outside in fall so long as they don't freeze, but they will probably be damaged.

The other group commonly sold traces ancestry to species like Phal. amboinensis, bellina, cornucervi, gigantea, lueddemaniana, venosa, violacea. Flowers don't have the round outline of the other group. The parent species have star shaped flowers, usually with plenty of space between flower segments. Flower parts may come to points rather than being rounded. They are often in shades of white, green, yellow or red, and frequently very fragrant. These have very pale green leaves, very shiny and succulent when healthy. They become less shiny when water or cold stressed. They tend to flower in summer. Spikes tend to open one or a few flowers at a time, but will continue producing flowers from the tip of the spike for more than one growing season. When larger and conditions are suitable they can be in near-constant bloom for many years. This group prefers warm jungle conditions: hot temperatures, high humidity. They may die if temperatures fall below 50 F / 10C. Many growers recommend never letting them fall below 70 F / 21C for best results. Many survive in the lower humidity of homes, but they are happier with higher humidity. Phal. bellina and gigantea are intolerant of cool temperatures and low humidity.

Phal. pulcherrima was formerly in a different genus, Doritis. It tolerates lower humidity, cooler temperatures and more light than other Phals. This is where the deeply saturated pinks come from in round-flowered Phals. This kind of Phal can tolerate cooler winter temperatures better than the white and light pink flowered hybrids.

Miniatures are being bred from Phal. equestris and similar species. They prefer warmer temperatures than most of the large, round-flowered hybrids, but don't need as much warmth as the star flowered jungle species. They accept the lower humidity of homes.

There are a few deciduous Phal. species from areas with very cool (but frost-free) winters. I'm not aware of them being used much in hybridization, but they might bring more cool tolerance.

To cut to recommendations -
If you run your house cool in winter, stick with the round-flowered larger hybrids, especially those with plenty of Phal. pulcherrima in the ancestry. A heat mat will be a big help.

If you like it warm in the house all winter, you can grow those, plus the Phal. equestris related species and hybrids. If your house is cool in winter, get a heat mat.

If you like it warm, and have some way of increasing the humidity, you can grow the star-flowered jungle species. If your house is cool and dry, put these into humid terrariums with some heat.

Auga gana puikiai. Pas mane buvo trys augaliukai net susodinti. Auginu ant palangės. Galėsiu nufotkint grįžus iš atostogų. Parodykit kaip jūsų atrodo
