Drought Busters

Midsummer in Carolina Country is often a time of high heat and cloudless skies, which leaves many a plant lover stressing over their pretties in the garden. Regular waterings and mulch will, of course, help, but many plants just don’t do well when the temperatures are scorching and rain is scarce. However, some do.

Here are some perennials I have grown in my garden that I call “drought busters” because, once established, they have performed well in wicked heat and extended dry times.

Autumn Sage (Salvia greggi). This Southwest native does best in sunny sites and, true to its origin prefers well-draining soil. Don’t let the name “autumn sage” fool you — my sassy pink “Lipstick” selection hasn’t been shy about blooming anytime during the growing season.

Anise Sage (Salvia guaranitica). Another tough sage, this one hails from the hot tropics of South America. Mine begin blooming around May and just keep rollin’ until the late fall. In particular, the cultivars “Black and Blue,” “Argentina Skies,” and the hybrid “Amistad” have performed like champs for me.

Lantana (Lantana camara). Have a garden with less-than-ideal soil in full sun? Lantana is your kinda plant. I’ve grown the old cultivar “Miss Huff” for years, not because I’m stuck on it, but rather, with minimum maintenance, nothing Mother Nature has thrown at this beautiful brute has killed it yet.

Purple Coneflower (Echinacea sp.). Being native plants, these tough beauties are used to surviving in the elements without human help, so in a cultivated garden, they thrive. Mine sure have. They not only flaunt the typical purple flowers, but also shine in shades of white, yellow, salmon and orange from newer cultivars.

Goldenrod (Solidago sp.). Another native that readily survives heat and drought in the wild, goldenrod, with its flashing yellow florets, is finally finding its way into backyard landscapes. New cultivars have even been developed, with “Fireworks” and “Golden Fleece” being two of the more popular.

Gaura (Oenothera lindheimeri). This native of Texas and Louisiana can take the Gulf Coast summer sizzle, so it is a dependable, tough-yet-pretty addition to gardens in our state with waving stems full of small, delicate flowers that start their shows in midsummer and continue until the first frosts. I have enjoyed the pink blossoms of “Siskiyou Pink” for many growing seasons. It is a common cultivar — in other words, easy to find — as is “Whirling Butterflies” with its wispy white blooms.

Queen Annes Lace

Garden To-Do's for August

Although pretty, Queen Anne’s lace is a Euro-Asian import that can aggressively spread in meadows, fallow fields and roadsides, making adding it to cultivated gardens questionable. However, the graceful white umbels, which are blooming now, can still add a special charm to your home this Christmas. Snip off blossom clusters at their bases and place them flat on a screen in a warm, dry spot. When it’s time to decorate your home for seasonal celebrations, lightly coat the dried blooms with hair spray to prevent shedding, and then adorn your Christmas tree with botanical “snowflakes!” Just be careful not to confuse it with the highly toxic Poison hemlock — its flowers are similar, although hemlock grows much taller with thicker, purple-spattered stems.

• While “Drought Busters” can survive high summer temperatures, some cool-season veggies actually need warm soil temperatures to develop properly and thrive, meaning this month is a fine time to begin planting such garden-grown delectables as mustard greens, radishes, spinach, onions (bulbs), lettuce (both leaf and head), kale, collards, broccoli, cabbage, carrots and cauliflower.
• If you enjoyed growing herbs such as dill, basil, oregano, chives and cilantro this year, allow a few plants of each to go to seed and fall in the garden. These seeds easily survive most winters outdoors in our state and will jump start your herb patch next spring.
