carex from seed
I want to try to grow some carex from seed but I have a few questions to anyone who might have experience.
1. Is it easy from seed? (I got the impression maybe some types vary from what I read online but nothing specific) Does it benefit from special treatment like stratifying? When is the best time to sow in pots or flats for plugs? Best sown indoors warm or outdoors cool?
2. I am interested in the fine bladed varieties like 'Flagellifera' 'Comans' and 'Testacea' for color and texture. Will these survive very hot summers with some irrigation?
3. Will they grow well in bright shade in summer? The area has full sun from September until early spring but is under a cedar that has branches high enough to walk under in summer casting shade most of the day during the days when the sun is highest. Will the cedar cause a problem with the soil? (the soil is pretty good but I can amend it if necessary)
4. I read you should divide the plants every 4 years to renew because it is short lived, does that mean the whole plant dies or just the centers?
