I haven't done so yet, but was watching Carol Klein do it on an older Gardeners world and I really want to try. I have a few varieties and so does my MIL, so might try to get some new version. I want to try with day lilies as well.
I LOVE ferns. I just started some more Ostrich and Christmas ferns this Spring from bulbs inside. I am acclimating them to outside just starting last night, as they are doing really well. It was such a success that I am going to now try ordering more tubers of various varieties and starting them indoors in late Winter for Early Spring planting. What I love about the ostrich, besides how amazing tall they are, is that their heads are the variety used in restaurant/food for fiddlehead salads! I just made over two new beds at our front door for Hosta/hydrangea/ferns and am going to put some of my Hellebore in there.
I watched the same one ( love Gardeners World)- and Carol is on the TV right now in Life in a Cottage Garden with Carol Klein :D Do you have your bit of ribbon ready for marking which ones you've cross pollinated?! I think I may have left it to late, they don't look like they have much flowering time left in them.
I didn't know that they used fern in salads! I have to keep my hostas in pots away from the snails, but that is still a loosing battle!
