Deck the halls with succulent monocots!

Agave neomexicana
Everyone knows how valuable conifers and broadleaf evergreens are for winter color. But the year around drama and beauty of succulent monocots--especially Agave, Yucca, Hesperaloe and Nolina--these are admired for their flowers and summer effect. But winter is when they reveal their stellar status!

Yucca schottii ?? in Watersmart

These pictures were all taken in the last few days--although still technically "autumn" we've had several snows and temps down to the lower teens pretty consistently. These, in any case, will hold up all winter like this!

Yucca linearifolia in Watersmat
Everyone wants these in their garden hereabouts!

Agave utahensis v. kaibabensis

Hesperaloe x 'Pink Parade'

Yucca baccata

Yucca faxoniana (left) Y. thompsoniana (middle) Yucca rostrata (right)
When Mountain States Nursery sent a semi load of these monsters to the Gardens in the late 1990's I had a conniption: surely these would be the most expensive annuals ever? But they (and Dan Johnson) knew better: these and the masses further out around the entrance to our Boetcher Education building are now labeled "Yuccarama" on our Gardens map (a jocular nickname we used at first that stuck!).

Agave parryi

Yucca rostrata 'Sapphire Skies'
Three of Sean Hogan's selection perched on three parapets at the west end of Watersmart--one day soon these will be a spectacle!

Agave neomexicana

Yucca elata

Yucca glauca
We even grow our local yokel that's found in vacant lots around town! Here in Sacred Earth--our ethnobotanical native garden.

Yucca harrimaniae
Easily 40 years old, this clump came from a collected specimen from Southwesternmost Wyoming--a gift of Budd Myers. It's turning into a miniature tree.

Yucca rupicola
One of my favorites--army green. It never ceases to amaze me how hardy plants are from the Edwards Plateau of Texas.

Yucca pallida
The OTHER Edwards Plateau endemic, also thriving here.

Agave lecheguilla (above) and A. neomexicana (below)


Yucca sp.
Not sure which species Mike Kintgen tucked at the top of the very first crevice garden at DBG...I'll fill in when he tells me.

Yucca filamentosa 'Color Guard'
Early morning picture: look how different it looks with backlight compared to the one below!

Taken in the evening half-light: looking quite different.

Yucca thompsoniana
Another tree yucca, this one on our parking structure.

Yucca harrimaniae
In 1980 I collected a series of Yuccas around the Uncompaghre--and planted them in a big semi-circle around the Upper Meadow of the Rock Alpine Garden: "they Persisted!"... they are surprisingly different from one another in bloom...

The "West Terrace" Nexus berm: from generic annuals to a desert extravaganza full of cacti, monocot succulents and more
I was startled when told this was planned: but I think it's already turning into a tour-de-force!


Agave toumeyana var. bella
One of the many choice morsels planted in the new terrace bed.

Nolina microcarpa


Denver is not the only place that monocot succulents are used effectively: this is a stunning garden in Pueblo that belongs to the Conrad family: one of Colorado's most spectacular gardens. Like a mini-Huntington--only with views of Pikes Peak and a huge pond!


A view down one of the Conrad's succulent planted slopes: what a collection!

Agave lecheguilla at the Conrad's


There's Pikes peak in the distance and the Conrad's pond below: this is a killer garden!



Bill Adams' greenhouse
Everyone needs enablers: we wouldn't have the enormous selection of rare plants available to us in Colorado without Bill Adams, whose Sunscapes nursery (www.sunscapes.net) has consistently supplied us with the choicest, rarest plants of all kinds. Including a revolutionary series of rosulate succulent hybrids (x Aloinanthus)! Bill is a national treasure.


Jeff Ottersberg stepping gingerly in his succulent garden
The ultimate enabler, Jeff's Wild Things nursery has provided literally tens of thousands of rare succulents (mostly natives) grown meticulously from seed to regional retail nurseries and our Botanic Gardens sales for decades. Jeff's plants are not only beautifully grown, they're ridiculously cheap.

Here Hans Graf (who owns the largest hardy cactus nursery in Europe) is admiring a plant with Jeff


A few of Jeff's treasures: that's Delosperma sphalmanthoides immediately at above these words. The first new species to be described from plants that came from Denver Botanic Gardens (ultimately from John Lavranos and Komsberg Pass).

More succulent gems to be sold next spring

Kelly Grummons
The "Hardy Cactus man", Kelly Grummons is not only a local leading purveyor of cacty, but Cold Hardy Cactus is providing these plants everywhere.

Cold Hardy Cactus views
He has an unparalleled selection of hardy cactus, yucca, agave, hesperaloe: you name it! Many superior selections and hybrids. And you can buy these now!

And many plants outside as well...



A greenhouse full of gallon sized agaves and manzanitas galore. All selling for ridiculously cheap prices.

There is no reason you can't fill your garden with these treasures. I know I've got more than my share growing at Quince: come by some time next spring and you will be evergreen with envy!

  1. Panayoti,
    Major gratitude for this overview of cacti and succulents that you at DBG had the progressive foresight to grow and the favored few gentlemen bringing these hardy and tough plants, often with spectacular flowers, to local gardeners. Just of late, trying my hand with rosulate succulent hybrids (x Aloinanthus) grown by Sam Hitt here in Santa Fe. Yucca thompsoniana and rostrada
    are among my favorites of the tree varieties and lend such an 'exotic' look to our landscapes.

  3. Such a timely post for the "quiet time" of our gardening year! These men are brilliant. Panayoti, your blog is simply the best in North America and you are a national treasure. Can you PLEASE write a blog on Sean Hogan in the near future?
