Ruth Bancroft Garden in the spring

Last Saturday I went to the spring plant sale at Ruth Bancroft Garden in Walnut Creek, CA. Click here to read my write up about the sale.

After I had picked out what I wanted, I wandered through this 3-acre succulent wonderland to check up on my favorite plants and to take photos for this blog. I visit three or four times a year and every time I find something new and different—not surprising considering there are thousands upon thousands of plants. One of these days I’ll try to find out how many species of succulents there are in the Garden’s collections.

The first thing you see as you enter the Garden through the north entrance is a fantastic array of agaves, yuccas and dasylirions interspersed with shorter columnar cacti.

The most exciting discovery for me this past Saturday was this blooming Euphorbia caput-medusae. The flowers on most succulent euphorbias are small and plain, but I found these to be simply beautiful.

Inside the Garden I found a similar euphorbia, Euphorbia inermis var. huttonae, although it wasn’t in bloom yet (apparently it has the regular yellow euphorbia flowers). This specimen formed an almost perfect Medusa’s head.

Right next to it in the euphorbia section is this aggressively clumping species. I love the mats it forms, but I wasn’t able to identify it.

Needless to say these euphorbias weren’t the only plants of interest. In fact, they were just the tip of the proverbial iceberg.

120414_RBG_Dyckia Senecio-mandraliscae
Unidentified dyckia species surrounded by trailing Senecio mandraliscae
120414_RBG_Tulipa-saxatilis- -Brunsvigia-josephinae_05
Tulipa saxatilis, a wild tulip native to the Greek island of Crete, and Brunsvigia josephinae, a South African bulb which can become massive over time
120414_RBG_Gasteria-sp
Unidentified Gasteria species. I’m not used to gasterias forming such an open rosette (and having such long, pointed leaves).
120414_RBG_Bulbinella-nutans_01
Bulbinella nutans, a South African succulent whose flowers are a dead ringer for my old friend Bulbine frutescens, aka Cape balsam
120414_RBG_Aloe-striata
Coral aloe (Aloe striata) hybrids. Coral aloe is quite promiscuous and readily makes babies with other aloe species.

As nice as the Echeveria glauca in the lower right are, the real stars here are the
Aloe capitata var. quartziticola

Aloe capitata var. quartziticola
My one true aloe love!
120414_RBG_Senicio-kleinia- -Echeveria-glauca
More Echeveria glauca from Mexico and Senecio kleinia from the Canary Islands
120414_RBG_Aeonium-smithii_01
Aeonium smithii, one of the less frequently seen aeonium species, probably because it’s not as showy as some of its larger cousins. It’s not always size that matters!
120414_RBG_Aeonium-De-Cabrillo_02
Another rare aeonium, Aeonium leucoblepharum ‘De Cabrillo’. They had some in the spring plant sale, and in hindsight I should have snapped one up.
120414_RBG_aeoniums-on-rock
I love how this small aeonium species has filled the cracks between the rocks
120414_RBG_aeoniums porkandbeans
Aeoniums (green) and pork-and-beans sedum (Sedum rubrotinctum)
120414_RBG_Agave-americana-mediopicta-alba- -aeonium
Peek-a-book aeonium between the leaves of an Agave americana ‘Mediopicta Aurea’
120414_RBG_Aeonium hand
Unidentified variegated aeonium with a giant rosette (that’s my hand for comparison)
120414_RBG_Agave-attenuata-Boutin-Blue- -Aloe-plicatilis_01
Agave attenuata ‘Boutin Blue’ (formerly known as ‘Nova’)
and fan aloe (Aloe plicatilis) on the right
120414_RBG_Agave-attenuata-Boutin-Blue_103
Agave attenuata ‘Boutin Blue’: massive, solitary, and blue. When I saw it, I wanted to weep because mine (which I’ve coddled for four years) is a small runt. Mine is in a container, theirs has free root run. Maybe that’s the difference?
120414_RBG_Agave-attenuata_01
For comparison, a regular green Agave attenuata. Still, this colony is an impressive sight, especially for an inland location where Agave attenuata is notoriously difficult to keep alive, let alone make thrive.

Massive inflorescence on Yucca treculeana

If you’re ever in the Bay Area, Ruth Bancroft Garden is a must-see destination. It’s less than an hour from San Francisco.

They also offer a variety of interesting events, including an Agaves and Aloes Theme Tour this coming Saturday, April 21, at 10am. Check out their online calendar.

    1. Thank you, Loree! As you can see, the weather was quite different from when you were there. Spring sunshine may be welcome, but it's not so good for photography :-(.
