This winter took out several of our trial barrel cactus, but despite the losses, we’ve still got a good selection of survivors. Peak flowering season is late April through late May, so below are a few that we’ve manage to photograph during that period. The key for growing barrel cactus in cold wet climates is excellent winter drainage and bright sun. There are many genera to choose from, as you’ll see below.
Coryphantha scheeri is a Chihuahuan desert species that ranges from Texas south into Northern Mexico.
Coryphantha macromeris ssp. runyonii is a sea level species that’s only found on both sides of the Rio Grande River, which divides the United States and Mexico.
Echinocereus coccineus is native to much of the Southwestern US. This seed grown collection hails from Hudspeth County, TX.
Echinocereus x roetteri is one of our favorites. This naturally occurring hybrid between Echinocereus coccineus and Echinocereus dasyacanthus has flower colors that range through the entire rainbow spectrum. This is a stunning purple flowered form, we grew from seed from Pecos. County, TX.
Echinocereus palmeri is another Chihuan Desert species from Northern Mexico.
Echinocereus papillosus var. angusticeps stradles the Texas/Mexico line. Our plants sailed through our 11F winter.
This beautiful clump of Echinocereus reichenbachii var. baileyi was grown from seed from a population in Granite, Oklahoma.
Gymnocalycium deeszianum hails from south of the Equator in the Cordoba Province of Argentina. Unlike most of the previous cactus, which tolerate or prefer alkaline soils, gymnocalycium prefer acidic soils.
Notocactus floricomis is another superb performer from Argentina
Notocactus x hertonis is from a Mike Papay cross of the pink flowering Notocactus herteri and the yellow-flowering Notocactus ottonis.
Finally, Notocactus x subteri is another superb Mike Papay hybrid of the pink-flowering Notocactus herteri and the yellow-flowered Notocactus submamulosus.
