The tall everlasting was collected and described by the botanist and explorer Allan Cunningham in Augustin Pyramus de Candolle's 1838 work Prodromus Systematis Naturalis Regni Vegetabilis as Helichrysum elatum,[1][2] the species name being the Latin adjective elatus 'tall'.[3] The large genus Helichrysum was long recognised as polyphyletic and many of its members have been transferred to new genera. Botanist Paul G. Wilson erected the new genus Coronidium for 17 species of daisy of the eastern states of Australia,[4] and it was given its new name of C. elatum in 2008.[5] Three subspecies are recognised, two of which are highly restricted in distribution. Subspecies vellerosum is found on the summit of Mount Warning and is more woolly-leaved and reaches a height of 1 m (3 ft), and subspecies minus is found only at Point Lookout in New England National Park. Reaching 80 cm high, it has smaller and thinner leaves than the nominate subspecies.[4]

Here is a link that might be useful: Coronidium elatum

It looks like the last response to my posting should have gone somewhere else.

Please note the pdf of Northeast native nurseries, noted in myh posting, has been scanned with Avast antivirus and also with Malwarebytes to make sure they're clean.

It is very interesting to see what is going on in the northeast North America temperate climate plant world.

You could reach more people if perhaps you created a blog (Blogspot is easy to use, no cost to you) with this information. That way people that are searching the internet will find what you've compiled.

I'm sorry but that link to Coronidium elatum goes to someplace weird. Are you sure that is correct?

The registration date of that individual is the same that the date of the post. It was likely made to improve the chance of getting a hit for the site on a search engine. The text posted was probably cut and pasted from somewhere else to make it appear relevant to this forum. Happens a lot here as these forums are not monitored very closely.
