This one tolerates morning and evening sun and heat well without the leaves frying. Stays green too. Only thing that bothers it is wind. The wind cuts up the leaves easily.

I really love this variant - the mature specimen is truly spectacular. Mine is a 3 foot tall, 5 foot wide mound of bright green leaves that really is a show-stopper.
The only thing I might add is that apparently EARWIGS like it too, in addition to the slugs and snails. This isn't a waxy hosta, so be prepared to fend off the bugs looking for the salad bar.

This is one hosta I'll never be without. I've been growing 'Royal' for years and has survived our droughts. I have no slugs or snail problems with mine, give it very little water or food and it always rewards me.
I'm surprised to see notes that the blooms are only 'slightly fragrant', mine have a rich lily-like scent that fills my hillside garden each August.

I have been growing Royal Standard Hostas in the full (northern exposure) sun and partial shade for over 10 years in Florida, first in Leesburg (Zone 9a) for over 5 years and in Orlando (Zone 9b) for 5 years. They are wonderfully fragrant, bloom profusely twice a year and I have had blooms as early as March. The only downside is the same problem up north - snails and slugs. They need consistant watering and I baby them but they are worth it.

ROYAL STANDARD is one of very few Hostas that can be grown in Zone 8b Florida. Here, it makes two flushes of bloom, with the second coming as the last flowers of the first flush fade. I have it in filtered shade under a fairly large Redbud Tree, and it has done very well for me.

Very fast growing, and produces a large number of fragrant flowers. Mine tolerates a couple hours of direct morning sun and looks great. Scapes get about 30"-40" high.

Royal Standard is a fast growing hosta that can take some sun and has attractive foliage. The plant in the pix shows some sport leaf and RS has many recognize sports. Was introduced in to the mail order trade in1964.
