I was in the woods yesterday and decided to go by and check
on the Potato Dandelion, Krigia dandelion, tubers that I transplanted last August. At least a few of the tubers
survived and have developed clusters of leaves.
I planted over 50 tubers along this ridgetop, but only found
a small number of plants yesterday. The
bare ground chosen to receive the tubers in August has since been covered by
fallen leaves. By late April the Krigia plants
will have developed enough for the leaves to be easily seen above the forest
leaf litter.
In addition to planting tubers in the woods, I introduced a
few into a new container. These plants
are growing in a 22 inch diameter container that had been filled with recycled
potting soil. First growth appeared in late
September. Growth was rapid until the
sub-freezing weather arrived.
Leaves show signs of stress from exposure to cold, dry
air. Each warm spell allows the plant to
increase the size of the youngest leaves emerging from the center of the
rosette.
This is the seven inch diameter pot that housed the stray
Potato Dandelions found growing in the burned shed site last April. After sifting out the large tubers last
August, I returned the soil to the pot.
There were enough small tubers left in the soil to produce this growth.
A few drops of water, left by the rain a few days ago,
remain frozen on the leaves. I’ve seen
these plants receive much worse damage than this and still recover with the
return of warm weather. So much about this
species suggests that it should thrive in this area, but it still remains a
rarity in Ohio.
This 18 inch diameter container has been producing Potato
Dandelions for many years. Somehow, this
pot has become contaminated with Chickweed.
After harvesting the tubers in August, I’ll add a couple inches of fresh
soil to this container. That should
reduce the possibility of Chickweed next year.
Leaf damage is not quite as bad in this container, even
though there are still ice crystals sitting on the leaves.
Most of the plants show minimal damage. All three pots are situated in different
locations and this pot was in a position that allowed snow blowing from the
barn roof to cover most of the plants.
The snow protected the leaves from the dry air, which seems to be the
major cause of leaf damage. I hope to
have an abundance of tubers for transplanting next summer. Given time, I should be able to find other
suitable locations in which this plant can thrive at Blue Jay Barrens.
Based upon a casual look at flower and leaves, I've long assumed we had potato dandelions here on our place in the Arkansas Ozarks. I guess it a sign that dandelions usually get no respect, that I've never taken the time to confirm my ID, or to dig one up and find its potato.
ReplyDeleteHi, Marvin. I suspect this species is more abundant than commonly believed. The tubers usually grow at a shallow depth, so it's easy to brush a little soil aside to make certain of the ID.
