Sticking Lavender in the Greenhouse

One of the most effective ways to generate a multitude of plants is to grow your own from cuttings that will get a good start in the greenhouse. This month, I’m talking with Nancy Connolly Blum, a professional landscape gardener and former owner of the Sawmill Ballroom Lavender Farm in Oregon. Here are the propagation […]

Low Growers with High Expectations

Ideally, plants in gardens and greenhouses are designed in layers. And the most neglected layer is right at the bottom—the groundcovers. Using living plant material instead of just mulch makes for easier maintenance, and less weeding. This is true in garden beds and in containers, where shallow-rooted groundcovers do not compete with their deeper-rooted companions. […]

Jellyfish in the Glasshouse — Great Ideas from the Northwest Flower & Garden Festival

Growing Artichokes in New England

Here in coastal Rhode Island, I live in the US Department of Agriculture’s Plant Hardiness Zone 7a. This zone has a medium-length growing season and winter temperatures that, at their coldest, can drop to between 0° and 5°F. This makes growing artichokes outdoors difficult. These plants prefer a more temperate climate because most set buds […]

Weather is Coming—Will We Be Prepared?

I was all set to write about the latest Hartley greenhouse that will be gracing Seattle’s Northwest Flower & Garden Festival—next month I will bring you that—but now, life (and the weather) has interfered with my plans.

Why Do Plants Look Good in the Store and Then Do Badly at Home?

When you go to a garden center, the plants look wonderfully healthy and vigorous, so you buy lots of them.

First their growth may slow; then they may stop flowering; and finally they may start to […]

Christmas Trees Wanted: dead or alive?

 The holiday season is upon us and in the Clarke residence it shows its face with the resurrection and plugging in of the Psychedelic Christmas Tree. As a couple of old groovers, this totem has particular significance, marking our first Christmas in Iowa in a rental and not knowing a soul in the state. […]
