Blake, thank you so much for your follow-up question about what to plant instead of Crepe Myrtle. A gardening group that I belong to on Facebook had a newbie question about "What is this beautiful tree?" and folks were trying to persuade them not to plant it. I was challenged with, "Well, what would you suggest instead?" and could only come up with one answer. I have written down the different choices offered and will share them with the group.

That container scraping on the table!

How much sun is Confederate Ghost getting? Can it take full sun for most of the day in 7B?

Something to replace the nasty crepe myrtle? Yaupon Holly!!! Multi-stem, evergreen, and America's only caffeine-producing plant so you can get delicious tea all year long. Great for the ecosystem and great for the taste buds. You can't beat that combination, imo. I just wish more people were growing it in their yards. Got three of them going last year and they are doing well. It's still early days, but I hope they'll be around 12' tall soon.

Great information

Great discussion, thank you. Have a question about Cornus kousa 'Summer Fun'. I planted it under a large tree in spring of this year, it did get an hour or two of afternoon sun. But as soon as our temps climbed to 90s, it died. I live in zone 8a, NC. The question I have is, can it tolerate our heat, I want to try to grow it again.

💚💚💚

So glad you guys mentioned hedgerows. I’ve really been digging into them and love the natural services they provide. I think this would be a great topic for an individual talk.

Thank you for a wonderful presentation. Looking forward to reading the book!

Thank you Tim and Blake for an excellent presentation!

What a fantastic presentation. I learned a lot and I'm looking forward to reading the book.

Grew a guaranitica hybrid Salvia x Plum Crazy this summer, because of its performance in UGA trial. Nice magenta purple too. Not so "blue". Dark calyx, and good dark green foliage.

Perfect description of the heat domes that form over Texas and large city's that are covered with asphalt and concrete. There is nothing to absorb the heat and use it for growth instead of radiating it back into the environment. Concrete and asphalt are not discussed about their contribution to global warming. People don't look around them much when looking for a cause they look for someone else to blame.

To me as a gardener dirt is something that is on your shoes and soil is something plants grow in. ❤ . People say I must have a greenthumb and I say no its actually brown because you have to keep your hands in the soil to learn anything 😂.

I’ve not had luck with Nemarosa either in Savannah, GA. At 46.25, what is the name of the variety that Tim said was in the Sclarea sub group, is across from the rose garden and looks like a “giant Nemarosa”? Tx

Great video. You mentioned salvias creeping into the rose garden. Sarah Raven says she intentionally plants salvia with her roses because she thinks it cuts down on diseases and pests with the roses. Any evidence of that at JCRA?

You could say where the JC Raulston Arboretum is located. I don't think there was mention of that in this video. I had to look it up and found you are located in Raleigh, North Carolina. Thank you.

Love salvias! Great video!.... what was the video suggested at the beginning of the video?

Thank you for the tour! Excellent job!

Excellent Video. Thanks Mark!

New Japanese gardener here. Planning and grateful for info. Beautiful grounds!

Very interesting program, thank you Minus aliens stuff, are you familiar with these publications? Plants reflection of animals communication, animals and plants communication publication titled: Acoustic communication in plant-animal interactions, Current Opinion in Plant Biology, Volume 32, August 2016, Pages 88-95. please see-Sound evoking physiological changes in plants, check : Front Plant Sci. 2018; 9: 25. Published online 2018 Jan 30. doi: 10.3389/fpls.2018.00025. Alot of claims in the book are now confirmed in scientific publications. Regard to communication among plants see: Plant Signal Behav. 2012 Feb 1; 7(2): 222-226. Also see publication from Center for Research and Advanced Studies of the National Polytechnic Institute. The article called Plant Communication.

Nice job interns.

Great job! What an awesome internship program to entice these wonderful talents!!!

Great job interns.

Great presentations by all

I've heard that you can grow Gloriosa rothschildiana on long island when you give them a good mulch for winter.

I have always wondered how to make these! How about a video on how those beautiful giant concrete (or plaster?) leaf castings around the arboretum are made?

Yeah! I’ll give this a try. Two questions: should you have put plastic over those bricks before smushing on the hypertufa mix? Did you make the square planter behind you in the video?

Mark I have seen people immerse hypertufa in water after a 24 to 48 hour set time and leave it for weeks or months. What do you say about this practice. Also can you use permatil instead of another medium. Thank you so very much for your consideration of plants you like or describe in talks .

1/1/1 even I can remember that.

Love this. I have done this using a old basket for added texture on the outside.

I’m in zone 8b 9a in PNW but the problem is we have really wet cool winters which a lot of the palms don’t like. I know some people who can grow Washingtonian palms in colder zones than me like zone 7b since they are in a dryer area

very thorough. Love the plant list!

Great picks and explanations by all interns! Well done!

I know fishermen who grow chitalpa trees just to get those sphinx moth caterpillars for fishing bait.

My deer love fuchsia sanihof

I thought that dessert willow was chitalpa tree?

Nice presentations😊

Platycrater is tea of heaven

Ailanthus likto spread

Good job to all the interns.

I think 'tree of heaven' is invasive in zone 9. Is that right?

why it's so long

I have several different Bletilla cultivar in my garden, Buffalo, New York zone 6b. I have found that growing them in full sun, but with a cool root system like clematis, shaded by evergreen ground cover. Fixes a lot of the problems that you mentioned.. I just posted a video on my channel about my Hardy orchids.

Thank you for this video. I would like to see more videos going to more details about watering and potting media needed to maintain the survival of orchids at home. I have a various orchid types at home. Overwatering seems to be the major issue for most orchid growers. Orchid disease is next.

Great presentation. Dr. Raulston would be pleased.

It’s been a few weeks, so I’m assuming you guys made it out alive after this one 🤪 Awesome midweek!

Thanks for another informative and inspiring program. Love the enthusiasm and varied knowledge you share. After over a month with only one superficial rainfall in 8b Georgia, I'm wondering if opting for less lush and more simple, meditative style garden might be more conducive to feeling a connectness to my garden, rather than the slightly frantic "gotta keep them alive" relationship I experience now.
