citronelle has been the best one I own. It is never small all summer and winter it only loses a couple of leaves so it comes back a large plant in the Spring.
It has been in this pot for 3 yrs this is yr 4.
I plant all my plants in pots which has given me success the last two years. They were always dead or so small after winter and slowly would die through the summer.
I use coir pots which give them perfect drainage I line them with oak leaves and fill with my homemade compost soil
Once I place them in the garden you cannot see they are in pots. When winter comes I remove them and place them in a corner on the patio and cover with leaves.
Here are some lined up ready to be placed in the hosta garden.
