Plant in full sun to light shade (much whiter gray with brighter light) and irrigate little to occasionally. Hardiness is not well known but we did not have any damage on a small plant left outside in our January 2007 cold spell, when we had several nights down to 25 F. This plant is an older hybrid attributed to Ed Hummel and is thought to be the result of crossing Kalanchoe beharensis with K. millotii. We first noted this plant on the coastal bluffs in Malibu on a private property that “Grassman” John Greenlee had planted with many succulents, coral trees, New Zealand flax and grasses. This Kalanchoe was growing right on the edge of the cliffs overlooking the Pacific Ocean, with little or no supplemental irrigation and looked great. Our thanks go to John Greenlee for sharing pieces of this durable gem and for John Trager at the Huntington Botanic Garden in his help identifying it. The information on this page is based on research conducted on this plant in our nursery library, from online sources, as well as from observations made of it as it grows in our nursery, in the nursery’s garden and in other gardens where we have observed it. We will also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural tips that would aid others in growing Kalanchoe ‘Oak Leaf’.
Oak leaf Kalanchoe
$1,500 – $3,000
Kalanchoe ‘Oak Leaf’ (Dwarf Velvet Plant) – A densely-branched shrub to 2 to 3 feet tall with fuzzy, gray, lobed and upwardly-cupped 3 to 4 inch long succulent leaves that have broadly dentate margins. In midsummer appear the branching stems with small flesh-colored flowers in tight cymes at the branch tips just above the foliage. This plant is similar to the Velvet Elephant Ear (Kalanchoe beharensis) but is a smaller and denser plant with much smaller leaves that are not nearly as rigid.
