    Brian Bixley sent along this note:

    The most charming comment on Minding The Garden: Lilactree Farm, a new gardening book that pushes the boundaries of the gardening literature, comes from an American purchaser’s comment on Amazon: ‘This is an outstanding gardening book - highly literate, witty, and engaging as the dickens. The author is based not in some ancestral English manse but on a frigid Canadian site he and his wife have developed themselves. I really like the serendipitous qualities of the book. There are 125 sections, some only a paragraph long, and you can savor them two or three at a time, like chocolates, all winter long.’ Get ordering Info

    Lost Horizons' stock is available at 20% off. Larry Davidson, the owner, has informed us that the nursery  will be open this fall from Wednesday to Sunday, 10AM - 5PM, for as long as the weather holds. If the weather turns nasty please call ahead to make sure they're open. They still hope the nursery will sell (glass quarter full) but if not it will be opening in the spring to sell off remaining stock.  http://www.losthorizons.ca

    This likely is a "brushing" scam. See https://fortune.com/2020/07/30/what-is-brushing-scam-china-mystery-seeds The Canadian Food Inspection Agency is warning Canadians not to plant packages of “unsolicited” seeds. The agency said in a statement that these seeds can contain invasive species and can be harmful to agricultural and natural areas.

Plant of the Month for November, 2020

 (or-ni-THOG-al-um  KAN-dee-kans)

General Information:

Ornithogalum candicans, is a tall, regal summer-flowering bulb that is little known in gardens. You might recognize it as Galtonia candicans. This plant was reclassified in 2004 when all of the Galtonia species were moved into the Ornithogalum genus, which I think is a shame since some of this genus, like star-of-Bethlehem, are garden thugs. O. candicans seeds very little and only at the base of the parent. It is no thug.
