Gardeners' Notes:


On Sep 8, 2020, DDruff from Mesa, AZ (Zone 9a) wrote:

A handsome plant sold in all the nurseries around here but hardly a hardy agave for the Phoenix area. It cant take the full sun in summer, and quickly swells and collapses to mush if you try a little additional water to help it through the season. Rabbits eat the pups and younger plants. I have a few more mature specimens that get some filtered shade and are better established, but in general, it is a temperamental plant. Hardier and trouble-free agaves for the Sonoran desert would be sharkskins, octopus, or artichoke agaves. I wish the nurseries in town would provide better guidance and advice when selling these overly popular but far less resilient Frankenplants.

I was shocked to find my underpotted agave which I had neglected to bring indoors before going to Mexico for a week when it was 23 degrees, 25 degrees and 28 degrees 3 nights in a row and the daytime high those days was 40 degrees of less.

Very excited to report that today it was completely unphased and shows absolutely no signs of frost damage.

I am amazed. I have plans to bring it in as the next few nights will be dropping to 20 and calling for ice and snow but I think this is an fantastic observance.

This agave is clearly taking after agave ocahui reportedly surviving down to 18 degree which san marcos growers website states that there is a report in California of this agave surviving 17 one night, which I completely believe.

Does anyone know if agave "blue glow" has its red rimmed leaves when very small (two inches tall)? I acquired a few of these plants recently that are supposed to be "blue glow" but have no red rim.

I bought a 1 1/2 foot across Blue Glow 5 years ago - it was probably 5 years old at the time. Four months ago it started to grow a flower spike from the center. It is now about 10 feet tall and the top 1/3 was covered in white flowers. The flowers are now gone and I'm waiting to see what happens next. There are numerous babies growing about the back of the original plant. I was told the entire original plant will die back and then I can harvest the babies to plant. I have photos of the progression if anyone is interested.

I have Blue Glow in a turquoise-color ceramic pot with two other agave types under a small ramada. Blue Glow receives morning sun and shade the rest of the day. It is doing well after one year.The plant is watered deeply about once every 2 1/2 weeks in summer and receives a diluted dose or two of fish emulsion fertilizer during the hot season. Great-looking agave and relatively small. Grows well in a stock cactus mix.

This plant is surprisingly cold hardy. The same plant that i posted as a small pup is now much larger and survived two winters in Bishop, CA where it had minimal leaf damage after clear nights of 9 degrees Fahrenheit and other nights of being covered in snow.

Gorgeous plant with a great hue for the desert. They have these now at some of the big box stores around Phoenix but be warned, I've come across a couple that were mislabeled.

Beautiful, fast-growing Agave. It needs some sun protection here in the Valley, and it's relatively defenseless. No spines save an unimpressive terminal spine, thin skin, and very fleshy leaves. Rabbits and rodents will have a field day if given half a chance.

This is a very beautiful agave. My garden is in the Sonora Desert south of Tucson, AZ in zone 9A. "Blue Glow" needs some protection from the summer sun here if the deep blue-green color is to be preserved. Both filtered shade for the entire day or or full sun for half of the day works well.

As Palmbob mentioned it seems to be quickly gaining popularity as we now are seeing quite a few at the Desert Botanical Garden in Phx AZ. One thing I have noticed as well is the price at which they are selling. Small plants are being priced at ~$70. which is hard to stomach. Not sure if the price is going up or I just got lucky. :)

Certainly one of my top 5 Agaves though... they are beautiful.

Supposed to be a cross between Agave attenuata and A ocahui. It's a nice looking plant. I am not sure, but it sounds like the A attenuata is the blue form?... doesn't look much like either plant- none of the soft edges of A attenuata (dangerous sharp long black terminal spine, and wide deep blue green leaves)... some teeth but they seem to taper out to nothing towards the leaf ends (at least in the seedlings). Supposed to get up to 3-4' across eventually.

Sure enough as soon as I see at one nursery, all C&S nurseries seem to have it now. I see this phenomenon with a lot of 'new' plants.
