Plant Highlights By Date
Agave dasylirioides is single-headed, and when a plant flowers one must start over again from seed, since this is the end of its life-span. 2020 marks the first year we have ever had A. dasylirioides come into bloom, so this makes it a special occasion for us.
South Africa is home to many plants in the Ice Plant Family (Aizoaceae), and they are well-represented in the winter-rainfall area in the west of the country. A few of these are widely grown, but others are seldom seen in cultivation, as is the case with Wooleya farinosa.
At the Ruth Bancroft Garden we grow Trithrinax campestris, a palm native to northern Argentina and Uruguay. This species is known as the caranday palm, or alternatively as the blue needle palm, with the latter name referring to its sharp-tipped leaves.
Coryphantha is a genus of relatively small globular or short-columnar cacti native to the southwestern U.S. and Mexico. While some Coryphantha species are found over a large area, others are quite localized. One such localized species is Coryphantha tripugionacantha, which is found only in a remote area of far western Zacatecas in west-central Mexico.
Collectors have long been drawn to the many fascinating dwarf succulents in the genus Haworthia, native to southern Africa. One of the new genera is Tulista, with only four species, all of them found in the southwestern part of South Africa.
Among South Africa’s many species of Aloe are Aloe pearsonii and Aloe distans, two related species from the winter-rainfall region in the western part of the country. Read about what happened when the two species were hybridized.
Plants in the Amaryllis Family (Amaryllidaceae) are found around the world. Among the African species are several featured prominently in the plantings at the Ruth Bancroft Garden, and one of these is Boophone disticha.
Most of the cacti commonly referred to as “barrel cacti” belong to the genus Ferocactus, and these are found in the southwestern United States and through much of Mexico. One of the large species is Ferocactus pilosus, found in north-central to northeastern Mexico.
The plant named Banksia formosa was originally published as a Dryandra, and its common name of “showy dryandra” reflects this.
The genus Yucca is widespread in the southern part of the U.S. and southward to southern Mexico. Among the tree-like species, one of the better known is Yucca brevifolia, often referred to as the Joshua Tree.
