Last year I bought 3 Queen Mum Agapanthus plants. I planted them in a sheltered area. Now, these were truly a wonderful display, as they stood around 6 feet tall and the blooms were glorious. Now here we are this year in mid May, and I'm still waiting for them to start growing again. I know we had some hard frosts to -8c but according to the tag, they should be OK to -9.5. Just wondering if they will come back...will let you know if they do.
