Here are a few highlights:
■ Yew Dell Botanical Gardens in Crestwood: In the January/February issue of Horticulture magazine (Hortmag.com), Yew Dell is featured as one of the country's 10 inspiring public gardens that have opened in the past decade and are being restored, supported in part by the national Garden Conservancy (Gardenconservancy.org.)
The garden's researchers study and develop plants that will thrive in this region, and they share their results in display gardens and programs such as the vegetable garden design seminar at 10 a.m. Feb. 11, and hellebore day, which begins at noon April 7. New varieties of this winter- blooming evergreen will be discussed and sold. Yew Dell is just east of Louisville at 6220 Old LaGrange Road. Traveling there from Lexington is an easy day trip. Find a full schedule and details at Yewdell.org.

Go to the horticulture page at www.ces.ca.uky.edu/fayette for information.
■ Seed and garden catalogues: Winners and survivors in this year's catalogues are not only gorgeous and tasty but have been selected for their ability to withstand the elements and extend the growing season. High Country Gardens (Highcountrygardens.com) supplies plants that generally require only moderate watering. Take a look at the new annual blue Serena Angelonia, which I had a chance to preview in my garden last summer. Compact 12-inch spikes of small blue flowers that appear delicate but act tough form a perfect backdrop behind spreading white petunias and golden marigolds. You also can find a great collection of ornamental grasses to add four-season interest in your landscape.
The herbaceous perennial Brunnera macrophylla, named Jack Frost for the silvery-white variegation that ices its otherwise rich green, heart-shaped foliage, is a shade-lover that tolerates sun well. Its spring-blooming, true-blue flowers look a lot like classic forget-me-nots, but the foliage is the main attraction for most of the summer. It was named the 2012 perennial plant of the year by the Perennial Plant Association (Perennialplant.org), so you should be able to find it easily in garden stores or from mail-order sources such as White Flower Farm (Whiteflowerfarm.com.)

Sunshine Daydream is the 2012 award winner from All-America Rose Selections (Rose.org). A mellow-yellow grandiflora, it's a continuous bloomer with lustrous, deep green foliage that resists black spot. This is the first year that AARS roses were judged under "no spraying" regulations, with an eye toward choosing roses that could be grown sustainably in home gardens. You can find it at Wayside Gardens (Waysidegardens.com.)
