    to your woods and coastline, OD. Such a beautiful place! About one of the pine growing out of rock, you said:

    It's older than you might think, in these conditions.
    Truly! Growing on rock can't provide much in the way of nutrients, so it must grow very slowly. A naturalist with the Buffalo National River in the Arkansas Ozarks said there are cedars on its spectacular bluffs that are hundreds of years old, but quite small. Nice adaptation!

    I won't be hiking those bluffs to see to see them, but we have a three-year-old cedar growing on a boulder by a creek in the holler near Cotter, Ark. It seems to  be doing well -- no doubt getting some short-term soil in runoff from the hill when it rains. It's mighty tempting to give it a few handfuls of dirt when I visit. Seems like it couldn't hurt ;)

    In my backyard on the bluff, the neighbors' peonies have plump buds, but mine have none at all. Mine are next to a second-year redbud that recently emerged tall and leafy from its competition with the honeysuckle. Makes me wonder if some underground competition among the roots for nutrients has delayed the peonies.

    It's clear and cool here, 68 with only a few puffy white clouds. One of those perfect days.

    •  Yes! A few handfuls of dirt, why not. (12+ / 0-)

      It must be hard being a tree, making do with what's under it, unable to seek out what else it needs. Although I've been fascinated to learn the new discoveries about the networks of fungi underground that trees benefit from. Not only do they bring the tree needed nutrients, but apparently also news about dangers nearby, so trees can prepare. But the ground has to be reasonably intact, to support the whole multi-species system. I'll track down that recent article about communication.

      Age, yah. On the path out to the bluff yesterday I passed a tree that had fallen and been cut up by the county to get it out of the way. It was less than a foot and a half in diameter and I counted 120 rings. Slow growing indeed.

      Hope your peonies are just late. Those flowers are glorious. I used to have peonies but they got shaded by trees. A loss.

      Enjoy your beautiful spring day!

      •  Underground network of fungi! (11+ / 0-)

        So fascinating, I found an interesting piece at BBC News. I had no idea plants communicated among themselves! A snip:

        Plants can communicate the onset of an attack from aphids by making use of an underground network of fungi, researchers have found.

        Instances of plant communication through the air have been documented, in which chemicals emitted by a damaged plant can be picked up by a neighbour.

        But below ground, most land plants are connected by fungi called mycorrhizae. ....

        As the researchers allowed single plants in the sets to be infested with aphids, they found that if the infested plant was connected to another by the mycorrhizae, the un-infested plant began to mount its chemical defence.

        Those unconnected by the networks appeared not to receive the signal of attack, and showed no chemical response.

        Thank you!!
