Good evening folks! I received blessings from Pitimpinai :)
She gave me these grasses. Can I put them in full sun?
Yes...they would prefer full sun.
I have a piece of Mone's Yaku Jima also. It's still in a pot, but will be installed as soon as I see if it survived winter.
Which one is taller? What will be their height in September? I need this info so I can decide where to plant them.
'Yaku Jima' will be a bit taller. Foliage to 50" and blooms to 60". It blooms earlier, too...~August.
'Morning Light' is 40" in foliage and 60" in blooms, and it blooms in ~September.
These heights are always dependent upon conditions, as is bloom time.
You can find this information yourself on Bluestem's Grass Comparison Chart:
Thanks for the link.
The clump I received was 11" in diameter. I planted it today. Will it bloom this year?
I'd say it will. Every Miscanthus I've transplanted or divided and transplanted has bloomed in it's next bloom season. It's usually a fairly sparse bloom, compared to an established plant.
