Hi Marilyn Long time no see . I know communications are a bit difficult with space crackle and alien gibildy glop.

Hi Arif!

Long time no see!

How are you?

We are finally getting some warmer weather here.

Are you growing Agastaches and Salvias?

Marilyn

Salvias seem to grow wild in this part of the world. Marilyn how much heat can these things take, could you please let me know. Not the wild ones but the domesticated ones.

I do not know the parentage of the above but these are the ones that I have planted. You all being experts can tell me what they are. Getting belly aches because the temperature, day time has reached 37c. Plus I have seedling of that scarlet salvia which someone said was Salvia aegyptiaca but after going through wild salvias I have my suspicions.

Above is aegyptiaca while I cannot find the photographs of the ones I planted. Have to sort out the photographs.

The Salvias in your pic look to be the short annual ones we have here in the US.

I'm not sure how much heat you are talking about. I'm zone 6a. Which is....

-23.3 °C (-10 °F) to -20.6 °C (-5 °F)

The temps will get hotter than my zone 6a. Zone 11 is the hottest in the database. Not sure what those temps are.

Hopefully, the others will comment on your questions.

Arif,
They look like the dwarf, cultivated versions of Salvia splendens to me. The species is a tropical sage, originally native to Brazil, so it is accustomed to warm temperatures but in an environment of high humidity and ample rainfall. I'm guessing that in your hot and arid climate (if my memory is correct in your location) you'll want to give them some afternoon shade and plenty of water.

Thank you both. Danita I thought so. Am a bit worried about them, by heat I mean 44c average may peak to 46, UV index will be at least 11 and as to the humidity maybe 18% except Monsoons. Lets me see this experiment closely.
Regards,
Arif.

Arif, love the "pots"

Arlene which pots or have you seen my pots on some other threads? Thank you. Like plants which I seem to keep buying due to what is known here as "ants in the Pants syndrome" I also keep collecting pots. All shapes and sizes but in terracotta.
Regards,
Arif.

What looks like little plastic bags. I know plastic isn't kosher, but I do paper pots and they reminded me of them. Flexible and small enough to do individual plants.

I collect pots as well, but usually USED ones! I did break down and buy some at the Dollar Store when I was in Michigan visiting my family.

Lovely salvias, Arif. Those in your picture should take your heat just fine as long as you can keep them watered enough. I agree with Danita, some afternoon shade would help. Your terra cotta pots would also help keep the roots cool because they evaporate water through the clay. (but you have to water them more than plastic ones) I lived in Utah, Zone 5a (or b?) until 10 years ago. In summer we used to have daytime highs well into the 40C's for a few weeks in summer, and everyone grew those salvias successfully in their gardens. My kids still live there, and I created a perennial garden for my daughter & son-in-law over the last 5 years. The salvias will not survive through her winters there, but they are widely used as annuals.

I love the pale blue salvias you showed at the start of this thread and they obviously survive the winters where you are. If they are considered "weeds" I would be out there digging them up for my garden. The definition of a weed, as I know it, is any plant growing where you don't want it.

The zone designations aren't good indicators of how hot it will get, eg. spots in Arizona and S. California are the hottest in the US but are not zone 11. The zones are based on the average cold temps in winter, so you can judge plant hardiness. I now live in zone 9a and it does not ever get as hot here as it did when we lived in Utah zones 5-6. Our highest temperature last summer was 92deg.F or 33C. Down in the Florida Keys, zone 11, it is the same in summer, it hardly ever gets to the mid-90's. But it also never goes below 40ish in winter.
