Hi Nancy, I don't know where you are in zone 8 Calif. but probably Northern Calif.? The frost won't hurt them and in fact I think your difficulty would be more with not enough dormancy than anything else. As far as your now sunny garden, your biggest challenge will be water. If you can water a lot and often they should be fine. Think ahead of adding water holding mulches (not over the crown of the plant) and a good drip system. I'm growing quite a few hostas in half day, hot afternoon sun (in the 90-100 degree range). Very little burning happens and I have only moved one back into the shade in the third year. Good Luck, Myrle (McTavish)

what a name.. ninja.. but

anyway..

hosta REQUIRE full dormancy.. or sleep ... for something like 45 to 60 days ...

otherwise they would be a long lived annual.. that will eventually peter out ...

all that said.. they are ONLY shade tolerant ... and can handle a lot of sun ... if not full sun up my way ... GIVEN ENOUGH water ....

what they will do in z8 with lots of sun is unanswerable by me ...

Yup, as previously stated, Hosta are shade 'tolerant'. In their native lands, many grow in full sun. Again, as previously stated, WATER is the key. They may burn the first few years until root establishment, but then grow, baby, grow. Keep the faith, keep the Hosta!
