Hi, I noticed that certain parts of Illinois (including Champaign) were updated to be a Hardiness Zone 6a. That said, I am considering planting some Azalea shrubs that are rated for Zones 6-9. According to the grower, it can withstand temperatures as cold as -10F, which is the outer limit of our Zone. If I plant this shrub, can I reasonably expect it to do well in my area? For reference, I am looking at the Double Shot Salmon Azalea. Thanks!
