"Hanging Gardens" is a technical term. Really. It's in Stanley L. Welsh's "A Utah Flora."
And Zion National Park in Utah, USA has them. This early November....
The autumn colours were fine.
(Acer grandidentatum, Wasatch/Bigtooth Maple lends the reds among Utah Juniper, Juniperus osteosperma/utahensis; Piñon, Pinus edulis; Doug Fir, Pseudotsuga menziesii; Singleleaf Ash, Fraxinus anomala; Silktassel, Garrya flavescens, and probably other fun things )
In spring, Zion boasts its namesake flavour of the Shooting Star, Dodecatheon pulchellum var. zionense, quite growable and availabel for gardens (look it up if you don't know it; it is worth it!) which is celebrated in the park's signage and easily seen up-close on the Emerald Pools walk.
Zion is a good place for plant inspiration for dry gardens, as the area gets about 20 inches (50cm) of rain per year, which is weighed against a hot summer more reminiscent of a furnace than one in Denver, say. Great massive sandstone features channel, divert, and trap a certain amount of this water- a complex situation that favours a delightfully variable hanging-crevice garden flora:
Linanthastrum nuttallii, a new and charming plant to me. It had a confectionary odour that I can't name.
A Heuchera literally hangs out in the shadier places. Generally, one tends to find these lot on North sides, which protects thier evergreen sensibilities from winter sun-burn.
Zion is the only place where I've seen Shepherda rotundifolia hang and cascade downwards with its mirror-glittery leaves. It is a much-sought-after-in-gardens evergreen shrub.
This year in gardening seems to have been rough for everyone. Despite drought and a long, hot summer, nature still clips along, even beautifully. The plants at Zion don't care that Colorado's Reservoirs are quite down right now, and that a favourite and progressive gardening mail-order nursery has closed, or that my home squash crop was a bust. It's rather comforting, somehow.
May we emulate the levity and steadfastness of nature.
