Adiantum pedatum (Northern Maidenhair Fern)
I’ve posted pictures of this fern before and I’ll probably do so again. It’s a pretty fern and worth growing, if you have any interest in ferns. I actually have it in a less than ideal spot that gets pretty much full sun from about noon onwards. It would be happier in full shade. The Missouri Botanical Garden page on this plant says, “High summer heat may cause fronds to brown by mid to late summer, particularly if good soil moisture is not maintained and/or plants are grown in too much sun.” Yep, that happens here. I really need to move it, or at least take a piece or two of it to grow in a better location. It does amazingly well in the sun, but it could be so much happier.
