I am addicted to the Rhododendron species that are more tender , particularly those which require protection from the cold-blooded winter temperatures we get here in New England . If I lived in Seattle , Oregon , New Zealand or the United Kingdom where the mood is both cool in the summer , and winter are besotted and temperate , grow these rarely seen rhododendron would not be a job . But most of us subsist in areas where the temperature sack is too wide , where utmost heat or extreme cold makes any success with pinnace Rhody ’s nearly insufferable .
With a inhuman greenhouse like mine , where wintertime temperature stay near 40 deg . F in the winter , I ’ve notice that tropical and tender Rhododendrons thrive . Most of them perform splendid in crapper , where they can be hauled out in the summertime and kept under the shade of tree . They must never dry out , but with right care , many of these flora ( or pocket-size trees ) can make spectacular specimen plants . There was a clock time when land greenhouses and botanic garden often had displays of tender Rhododendrons , but today , only a few hoi polloi grow them as container plants , since modern homes have standard pressure that are too red-hot and dry with central heating , and New luxuries like insulation and reliable thermostats .
If you happen to own an onetime home , you may have some luck grow these plants indoors , with the best succeeder come from an unheated room , where there are bombastic window , and perhaps a window nates which has been convert into a works window with crushed rock in tray for added moisture . Ideally , success will descend easily with a chicken feed greenhouse , or a conservatory , where the air is hold open cool and perky . If you are interested in more info , check out theAmerican Rhododendron Society , and theRhododendron Species Foundationfor details and radio link to nurseries . For Vireya ’s , check out theVireya netsite .
The classic Rhododendron species for conservatory culture in containers are the Asian species , especially R. fragrantissimum , R. Fragrant , bell shaped white blossoms , which let in R. edgeworthii , R. nutallii and others . Perhaps the most tropical provide the brightest color , and those would be find in the radical bed as the Vireya ’s ( most are native to the cool misty pile slope on the island of Borneo ) . Few greenhouse sell Vireyas , butBovees Nurseryin Oregon is the act one pick , and this is the near time of year to arrange them .
R. sainpauli , a new coinage with very interesting flower . It would be great in a hang wooden slat field goal , as many Vireya like .
Vireyas make amazing potted plants , and of all of the bid Rhododendrons , are the best suited for naturalise on windowpane sill and plant windows , as long as nights are cool , and moisture can be bestow to the air .
