Wow, I didn't realize your zone is so low. Inspiring for me, for sure, as ours is Zone 3...
How old is your Cyp. Phillip? What sort of soil is it growing in? Do you do any amendments to the soil for your cyps?
Beautiful photos of your garden as usual. Love the peonies, especially that red Alexander Woollcott. Scrumptious! :drool:
Actually we are in a 4a canadian zone and a USDA 3 zone.
I bought the Cyp. Phillip in 2010. It was a blooming size plant from Fraser's Thimble Farms. The plant is grown in a ....acidic loam with a lot of compost. There is a mulch of dead leaves on top of the soil. So, there is nothing special in the soil. I bought 3 other Cyps the same years and they are near Philipp. Every plant are vigourous and bloomed this year (Aki Light, Aki Paster, Michael). I didn't want to grow them in special mix like a lot of growers do.
