Teucriums Are Deer-Proof Too

2024-06-27T19:27:53-07:00Categories: Blog, Garden Plants, perennials, Nora Harlow|

Those of us with unfenced gardens adjacent to wildlands usually learn the hard way which plants are ignored by browsing deer and which, without special protections, are not. It may seem that our choices in plants are rather limited, but lush and lovely deer-resistant gardens can be made. Madeira germander (Teucrium betonicum, in flower) with sages and santolina Perhaps the widest range of deer-resistant options for summer-dry climates lies within the Lamiaceae, or mint family, which includes among its more than two hundred genera many plants that are widely used in gardens where summers are dry -- salvia,

Lion’s Tail

2024-06-27T19:27:46-07:00Categories: Blog, Garden Plants, perennials, Nora Harlow|Tags: , |

Some plants just naturally bring out the child in all of us, and lion's tail (Leonotis leonurus) is surely one of them. The whorled clusters of softly woolly yet spiky-looking, neon orange flowers can look almost cartoonish --a caricature of flowers-- spaced out along emphatically upright, six- or even eight-foot stems. Leonotis leonurus in full bloom in the San Francisco Botanical Garden Of the nine to twelve or more recognized species of Leonotis, only lion's tail, a perennial or subshrub endemic to eastern South Africa, is reliably available in nurseries. Lion's ear (L. nepetifolia), an annual native from

Embracing Wildness and Change

2024-06-27T19:27:47-07:00Categories: Blog, California Native, Nora Harlow|Tags: , , |

It is possible that the most life-negating aspect of modern landscapes is the whole idea of landscape maintenance. Landscape maintenance implies -- no, insists -- that landscapes must be maintained as originally designed, whatever the costs and losses. A lightly maintained meadow garden in California In the service of what is called maintenance, most residential front yards and almost all commercial landscapes are forced into compliance, preserving the outlines of their original design but with virtually no sign of life. Shrubs considered too large or wrongly shaped are brutally distorted. Weeds and “bugs” are sprayed with pesticides. Soil,

Climate Change and Water Supply

2024-06-27T19:27:47-07:00Categories: Blog, Water, Climate, Nora Harlow|Tags: , |

Global temperatures have been rising at least since the middle of the last century, and most projections anticipate that this trend will continue. Effects of warming vary from one region of the world to another but prominently include the likelihood that precipitation will shift from snow to rain in many snow-fed watersheds. It is also likely that snow will melt faster and run off earlier, changing the timing of peak streamflow. Snow is an important, even critical, seasonal water source for many regions with large mountain ranges, including most summer-dry climates. Snowpack accumulates in the mountains in winter when demand

Mendocino Reed Grass

2024-06-27T19:27:44-07:00Categories: grasses, California Native, Nora Harlow|

Commonly known as Mendocino or leafy reed grass, Calamagrostis foliosa is usually described as having blue-green or gray-green leaves with seasonal tints of purplish red, but that's not how it presents itself in my garden. Calamagrostis foliosa flowering in California garden This cool-season bunchgrass is worth growing not for the color of its fine-textured leaves, which for me emerge a rather dull green and remain so throughout the seasons. I grow it for its manageable size, its pleasingly symmetrical form, and the improbably long-lasting, greenish white flowers that remain neatly arrayed on arching stems as they age to

Living with Wildfire

2024-06-27T19:26:31-07:00Categories: Blog, Nora Harlow|

The goal of "firewise" landscaping is to reduce the intensity of fire and slow its advance as it nears the house. The basic principles are simple and few. Harden the target by making the house as resistant to fire as possible. Keep the area next to the house free of anything that will burn. Design and maintain planted areas farther out to provide no continuous path for fire to reach the house or move up into the tops of trees. Retain sufficient vegetation to buffer the house from airborne embers. Low plantings and concrete patio next to house reduce

Wildland Invaders and Garden Thugs

2024-06-27T19:26:27-07:00Categories: Blog, weeds, Nora Harlow|Tags: , |

Plants that readily establish themselves in wildlands, on vacant city lots, and along rural roadsides typically are adapted to a wide range of environmental conditions. They are long lived, self-sow readily, and produce many flowers over a long season. Some bear abundant crops of fruit loved by birds and other wildlife. In other words, some of the same sorts of plants we seek out for our gardens are those most likely to take over and spread. Echium candicans, Pride of Madeira, in a California garden Most plants are not invasive in wildlands or even weedy in gardens. Many
