USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

2-4" tall x 15-30" wide. Lion's Spore is a little-known plant that is a fantastic, cold hardy succulent from the high elevations of the Drakensberg Mountains in Lesotho and South Africa. The small, 1/2" diameter, spineless stems grow to form large, tight mounds. I was thrilled to first see this species up around 9,000 ft. on the mountain flanks surrounding Tiffindell, South Africa. Here, old, mature specimens form huge mounds more than 3' in diameter! Plant in a well-drained soil, preferably on the south or west facing slope of a berm or hillside to facilitate good drainage. Does not like to sit under snow for extended periods of time; cover with plastic or row crop cover (frost blanket) in snowy winter climates. Our Lion's Spore is propagated from stem cuttings. Good for Firescaping

Tips For Growing Euphorbia (Spurge)

Euphorbia (Spurge) is a huge genus of annual, perennial and succulent species that can be found worldwide. All Spurge have milky sap that can be very irritating to eyes, nose and mouth tissue. Some species have poisonous sap.  Handle with care. Rabbit and deer proof.
Preferred growing conditions:

  • Plant in a fast draining, infertile soil with full sun. Avoid clay soils. Mulch with gravel or not at all.
  • Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
  • Deadheading recommended to prevent re-seeding, as some species can spread aggressively. Use gloves to protect hands from irritating sap.
  • Fertilize lightly in the fall with Yum Yum Mix.

Special comments

  • Succulent species have evergreen stems. Prune to shape in the spring if needed.
  • Cut back herbaceous species in late fall.
