I found several statements that aren´t accurate but i was intrigued by this one:

Livistona chinensis Chinese Fan Palm 9a

Livistona chinensis var. subglobosa Taiwan Fan Palm 8b

My experience is that the subglossa are hardier. I have left 5 gallon sizes of each outside in past winters and the L. chinensis fronds spotted with some damage to emerging leaves at 22 F in Jan. 2007. The L. c. var. subglossa(Trebrown Seeds, UK) had no damage. This winter we have had sunny days, 55-68 F but with many mid-30s F nights. The subglossas have been pushing new leaves in these temps but the regular L. chinensis are not showing growth. We had our first hard freeze last week, I moved the regular chinensis into the greenhouse but left out the subglossas to experience 25F and they are undamaged. With that said L. chinensis has a fairly large range and there is probably some variability in hardiness of different seed collections. I have read the subglossas are from southern Japan and the Ryuku Islands but have also heard those islands' population segregated as var. ryukuensis. L. chinensis is also from Kyushu and Shikoku, farther north, and should see colder weather. I don't know where they draw the line around each variety but these northernmost populations should be hardier. If you can find older cultivated trees from marginal climates such as N. Florida, N. California, Canberra, or Argentina for example, these probably have been selected by freezes over the years to be hardier. Same applies to Queens, etc. A few hundred years of cultivation and freeze culling probably yields individuals hardier than seeking out the coldest natural habitat for any given palm. Zone pushing has its dividends, especially if we could live to be 500, and see our mad-scientist style gardening projects to fruition. Good luck.

Alberto, I don't know if L. Chinensis Subglobosa is hardier than L. Chinensis Chinensis, because both the species don't show any damage after a temperature of -6,2°C, but for sure the Subglobosa ssp. is faster than Chinensis ssp. in my climate.

I hope to take pictures today and post them this evening.

Both the plants are sprouted in June 2009 and growed in the same condition.

Giuseppe, the seeds of both the plants come from Rome Botanical garden.

For sure Giuseppe, the LCC's seeds is elliptical while the LCS's seeds is ovoid.
