The Prairie experienced about 36 consecutive hours of temperatures below freezing in early January. The freezing temperatures did some damage to my agaves and a few other plants. I think everything will pull through, but here is a look at some of the damage.
Above is an Agave americana that a neighbor gave me a couple of years ago. It looked so healthy and blue at Christmas. I need to take a walk and see how the mother plant handled the cold.
I received this agave as a door prize at a Native Plant Society meeting. It is supposed to be a cross between Agave americana and Agave scabra. I can't tell. It looks like Agave americana to me, however it seems to have a little more freeze damage than the Agave americana. The pups to the left are completely burned.
Poor little Agave parryi v. Truncata. Its roots were infested with fire ants all summer and then the winter cold damaged the leaves.
Note the Four Nerve Daisy, Hymenoxys scaposa, and Prairie Verbena, Verbena bipinnatifida, seedlings in the decomposed granite. DG seems to be a great medium for sprouting seeds. I use DG as a mulch around all of my agaves.
This is an Opuntia prickly pear of some sort. The pads were all upright before the freeze. Now they are flopped over.
Finally, my toughest agave. This Agave neomexicana does not have a bit of freeze damage on its leaves.
I will know in a few months if any of the agaves will need to be replaced. If they do, I have a couple of Pale-Leaf Yucca, Yucca pallida, that are waiting to be planted.
