Cyathea dealbata available in USA?

Posted by leean_gardener (My Page) on

My boyfriend fell in love with the Ponga fern (cyathea dealbata) while visiting New Zealand and now I would like to buy it for him. I am having a hard time finding it, however. Is it for sale in the USA and if so, is it strictly an outdoor plant or could it be grown in a terrarium? Thanks!!!

I didnt have much luck finding it in the States either, but I did find this. (link below)

Although it would take a while you could grow them from spores. You might try the LAIFS sale Labor Day weekend.

RE: Cyathea dealbata available in USA?

If you do find a source would you share the info. ?? Cant't find anything locally except Australian lol
Would think they would do well in a terraium but what about the 6 meters tall with an equal spread?? That would be one large terrarium lol gary

Tree ferns don't really take to life indoors at home

All tree ferns are strictly 'outdoor plants'...assuming you live in a virtually frost-free part of the country. But with the cooler temperate New Zealand varieties, like Cyathea dealbata, that would also have to mean fairly cool summers as well - surely a contradiction in terms for most of the US that offers the necessary mild winter conditions. You guys can't win! So, for many people in the US, that leaves a cool and humid glasshouse or plant-orientated conservatory as the only way of maintaining tender tree ferns all year round.

Cyathea dealbata is not an easy tree fern to home-propagate unless you have access to freshly harvested spore. I've never heard of anybody succeeding with seed catalogue stock - although plenty of other species are possible via this route, I guess the viability for dealbata spore is too short for the turnaround of the mainstream distributors. A bare pot that never germinates is the only reward for all that time and effort. As for the terrarium option: they are easy to kill with over-watering, poor drainage and insufficient ventilation...everything that an inexperienced terrarium grower would inevitably run into. The other side of the coin is that a healthy dealbata sporeling would, hypothetically, outgrow any terrarium within a season or two...and then what would you do with it?

To source a ready-made garden specimen (assuming you have the climate) I'd be looking at Vancouver Island nurseries and seeing if there was any practical way of shipping a potted-up dealbata youngster from British Columbia back into the US. Can it be done with your red tape?

More on Cyatheas in terrariums...

Just thinking about the terrarium question one more time: it's not practical. Given the 'wingspan', and the flat low-lying frond characteristics of all the Cyatheas when small, you could barely maintain even one plant at a time in your terrarium - they'd be insufficient light or room for anything else to share the tank. And a shared community terrarium wouldn't easily allow you to progressively reduce the humidity to harden off the Cyathea prior to growing it on outside - the other little plants in there might crisp up. Try and find a garden specimen up North over the border and get it shipped down to you.
