I said I would try to remember to check on some of my plants that go into summer dormancy and here are some I noticed today before my camera went wonky!
'Sailing At Dawn'

'Enchanting Esmerelda'

'Paper Butterfly'

What specifically is it about the plants that means they are summer dormant? They all look like they have at least one plant which is producing new small leaves in the centre of the fan which to me means that they are not dormant. Were they dormant before and now they have broken their dormancy and are growing again?

@admmad, What I refer to as a period of where certain CVs disappear almost completely. This conditions occurs when our temperatures get extremely hot for very long periods of time.

I too have experienced this with a lot of my plants. They are however, breaking this condition and producing new growth from the center of the fans.

I do not have any photos right now but will attempt to get a few tomorrow morning, when it is in the 80 vs. 90s with a heat index of triple digits.

To me the plants are exhibiting summer dormancy because they are now only a small percentage of the size they were in late spring and early summer. It could be that they are coming out of dormancy and hopefully they will be large again by fall.

I noticed today that my Sailing at Dawn looks like it is losing fans, hope it recovers in the fall.

They will recover and often with more fans. From what I can tell it's a survival mode for when temps hover around 100 for days on end and water is in short supply. The foliage that comes back can sometimes be thin and wimpy but come spring everything is back to normal. I also have several that display summer dormancy and it's always about this time of year when it's really noticeable.

So glad you posted this Larry! I didn't know some CV's did this, I thought a couple of mine were dying on me but now I think they're pulling this trick.
