Thread OP

I have several large well established lithadora that have thrived on a burm I planted. They have been there for about 10 years. I live outside of Portland Or.. This year we had quite a dry cold spell and then some cold with snow. After the snow all of the lithadora turned black. What could be the cause and what can I do about it. Thank You!

@catdocrn... first of all.... Welcome! Welcome! Welcome!

I hate to say but they might have root rot. Can you dig one up and look at the roots and the crown?

Another problem is you mentioned a long dry spell, from what I read they do not tolerate any drought at all.

Parts of mine have black on them too. At this point in our weather (PNW) just leave them be. I have had them sprout and grow and others that die that turned black. It got a little cold for them here and I believe the black is frost burn. Come May they just might sunrise you.

Thanks I saw that. If you have a picture it would be great. I think I am close enough to 7b to make it work. I will put it in a raised bed or a pot. I got a 50 lb bag of perlite yesterday so drainage is no problem. LOL.

Here's 2 pictures. Every summer I give these plants a hair cut and cut all the dead stems from underneath the plants. They can get large.
Taken in June. This one takes over the entire corner of the rocky. This may have been after a trim. These plants are often hanging to the bottom of this wall.

Lithodora diffusa grows well in zone 9, whether we have a drought or excessive rainfall. It grows equally well in containers and in the ground. All of my lithodoras are growing in sunny spots. I had some in the shade, but they only lasted a few years.

Julia, do you know what kind of lithadora this is, maybe we could put it into the database. Beautiful picture!!

Sorry Susan, I planted about ten plants 20 years ago and no idea of the name.

Catdocrn, forgot to welcome you Welcome! Welcome! Keep us posted as to what happens to you black plants when it warms around here. I think you will be surprised with growth at least around the base..
