Been Watching the Stones

We’ve tried growing living stones (Lithops) a few times over the last decade in the garden, but could never get them to last longer than a couple of years. We weren’t loosing them to cold temperatures, but to moisture. So, when we built the crevice garden, lithops were one of the first plants we wanted to try again. We designed the crevices with overhangs to keep water completely off certain special plants, and that’s where we planted our seed-grown living stones.

For those who haven’t grown these irresistible gems, Lithops are South African succulents in the Azoiceae family, native to very dry and mostly tropical regions. They are prized for their odd appearance that consists of only two camouflouged succulent leaves.

We’ve never been able to coax a lithops to flower until last week. In their new crevice home, several finally decided to bloom this fall, with a sucession of flowers that still continues. We are currently growing only one species, Lithops aucampiae, but now that we’ve been successful, we’ve planted seed of more species to try. It takes us about 18 months from seed to get a plant large enough to go into the garden.

Despite everything written about lithops being tropical, we have not found this to be the case. Like so many plants, not enough people have been willing to experiment in colder climates in the right conditions. Of course, if you believe everything written on line, you’ll know for sure that they can’t take anything below 40 degrees F. Hint…ours have made it fine in the garden to 13F, so we expect them to tolerate even colder temperatures if kept dry. Wish us luck and be sure to check out the stones growing in the crevice during our next open house.

Cooperi…Aloe, not Alice

Our patch of Aloe cooperi has been beautiful in flower this summer, but every time I see it, my mind automatically associates it with rocker, Alice Cooper. I guess he made quite an impression on me as a child. Aloe cooperi is the hardiest of the aloes, first cousin to the better known Aloe vera. Aloe cooperi has been fine here in Zone 7b for decades, but we doubt it would be winter hardy much further north.

Upside down in Dry Shade

At our home, we have a very wide overhang which never sees any moisture, so we were looking for plants that would stay low, ideally evergreen, and would tolerate seriously dry shade. The answer was Echeveria ‘Topsy Turvy’. These patches of the Northern Mexican succulent, with blue-green foliage, have absolutely thrived here. While they probably wouldn’t be happy in deep shade, they love this high canopy with good light, but no sun. These were planted in 2018. We’d rate these as Zone 7b/8a if kept dry in winter.

Falling Waters in the Garden

Here’s a new photo we just took in the garden that showcases the amazing architecture of xMangave ‘Falling Waters’ when it reaches maturity…pretty amazing!

Find out more about xMangave and their uses as a container specimen on FaceBook @MadAboutMangave.

xMangave ‘Falling Waters’

The genus xmangave is an exotic botanical curiosity that was derived from a cross between an agave and a manfreda. Crosses between two genera are somewhat rare in cultivation and extremely rare in nature. However, agave and manfreda have broken all the rules and ‘hooked up’ on more than one occasion to produce the attractive offspring called x Mangave. The ‘x’ on the left side of Mangave tells you that it is a cross between different genera.
