Ostrich fern, Matteuccia struthiopteris The 'hedge' of Ostrich fern. Yes, they are in direct sun. They will burn in August, but survive. There is some mutual shading. Ferns were established when Hemlock trees (Tsuga canadensis) were present. They died due to Adelges tsugae. #fern #ferns

Sensitive Fern, Onocela sensibilis 360 Sensitive fern withers upon the first frost, thus its name The stalks with dark clumps of sporangia are last year's growth that have released their spores this spring #fern #ferns

Interrupted fern, Osmunda claytoniana 360 The sporangia are brown and mature. They appear about 1/3 up the plant. The sporangia 'interrupt' the frond, thus the name The sporangia shape is similar to Royal fern (Osmunda spectibilis), but in a different location. #fern #ferns

Royal fern, Osmunda spectibilis - The North American species of Royal fern 360 The sporangia are at the tip of the frond. In the video the tip is still green, but is rough and round, not leaf shaped. Will turn brown as the sporangia mature. Unique that the sporangia are the tip of the frond.

Christmas fern, Polystichum acrostichoides 360 The sporangia are 'naked' on the underside of the pinna at the upper 1/2 to 1/3 to the tip of the frond. The sporangia are green at this time. The underside is whitish green. The pinna will curl as the sporangia. #fern #ferns

Cinnamon fern, Osmundastrum cinnamomeum 360 The cinnamon colored spikes are the fertile fronds with specialized fronds where the sporangia grow, each with the spores of the fern. #fern #ferns

ATTENTION. This is NOT a 2024 repost. We are hiring NOW and the deadline for applying is fast approaching.

Interrupted fern, Osmunda claytoniana Close up of the fertile fronds having recently emerged. The sporangia of interrupted fern are found in three fertile pinna about a third of the way up the plant. The rest of the pinna are sterile. Thus its name interrupted. #ferns #ferns

Ferns, given time, seem to create 'fairy rings'. The scientific term is radial growth. It is a clonal ring, genet ring. Cinnamon fern (L), Royal fern (C), Interrupted fern (R) #fern #ferns

More 'family' resemblence. Cinnamon fern (L), Royal fern (C), Interrupted fern (R). All are members of the family Osmundaceae. Cinnamon fern has the thickest woolly coating. Royal fern is similar to cinnamon fern, but has brown/biege streaks. Interrupted fern is the thinnest. #fern #ferns

Wow! "This historical palaeobotanical collection comprises a large repository of plant fossils from the Portuguese Carboniferous, many of which are potentially new for science and need to be investigated in future studies."

It's spring, just a start of ferns. Left - Cinnamon fern. Osmundastrum cinnamomeum Right - Interrupted fern. Osmunda claytoniana One can see the 'family' resemblance. Both are members of the family Osmundaceae. Both have 'woolly' starts to their fiddleheads. Domestic plants #fernfriday
