Fern little earner

MOH doesn't like the ferns we have so much. But I do and as Head Gardener (I've just promoted myself!) I rescue the ones he tries to throw out. In the sprit of congeniality I thought I'd check out what's available to buy online. And there's some great site names - simply ferns and fernatrix. 

While browsing fernatrix I noticed the picture below, these are the ones I like over and above the more traditional ferns...

These are selling for eight quid each!!!  We have them growing in an old stair well in a secluded part of our garden, maybe I should go into business!!  Or at least, educate MOH!
