Plant of the Year 2025

Brunnera Macrophylla ‘Jack of Diamonds’ is the Plant of the Year for 2025, celebrated for its bold foliage and charming spring blooms. This shade-loving perennial features large, silver leaves with dramatic dark green veins, offering a striking visual appeal in gardens. In mid-to-late spring, its delicate baby blue, forget-me-not-like flowers add a touch of elegance, making it a perfect choice for shaded borders and woodland settings.

This plant may face challenges in Charleston’s climate, as it prefers cooler conditions and partial to full shade. While it can grow in USDA zones 3-8, Charleston (in zone 8b) might be on the warmer edge of its tolerance. If planted, it should be placed in shaded areas with consistently moist soil and protection from the intense summer heat to ensure its health.

Brunnera Macrophylla ‘Jack of Diamonds’:

  1. Placement: Plant in a shaded or partially shaded area, such as under trees or on the north side of buildings, to protect it from intense afternoon sun.
  2. Soil: Ensure the soil is rich, consistently moist, and well-draining. Add organic mulch around the plant base to retain moisture and regulate soil temperature.
  3. Watering: Keep the soil evenly moist but not waterlogged, especially during Charleston’s hot summers.
  4. Heat Protection: Use a layer of mulch to cool the roots and reduce water evaporation. Provide extra shade during the peak summer months if necessary.
  5. Maintenance: Prune back dead leaves and spent flowers to maintain its appearance. Monitor for slugs, which can be a problem in moist environments.

Flower of the Year 2025

Sunflowers have been crowned the Flower of the Year for 2025, symbolizing warmth, resilience, and optimism. Their vibrant yellow petals evoke feelings of joy and positivity, making them a timeless favorite for gardens and floral arrangements. Whether planted to brighten landscapes or used as cheerful décor, sunflowers continue to captivate enthusiasts with their enduring beauty and significance.

Sunflowers thrive in Charleston, South Carolina, due to the region’s warm, sunny climate and well-drained soil. They grow best in full sun and are highly tolerant of the summer heat and humidity typical of Charleston. Ensure they are planted in a spot with at least 6-8 hours of sunlight daily and provide moderate watering.

Sunflowers:

  1. Planting: Choose a location with full sun exposure, ensuring at least 6-8 hours of sunlight daily. Well-draining soil is essential to prevent root rot.
  2. Soil Preparation: Add organic matter, like compost, to improve soil fertility. Sunflowers prefer slightly acidic to neutral soil (pH 6.0-7.5).
  3. Watering: Water deeply but infrequently. Allow the topsoil to dry between waterings to encourage deep root growth. Avoid overwatering, especially in Charleston’s humid conditions.
  4. Pest Management: Keep an eye out for common pests like aphids or caterpillars. Use organic pest control methods, such as neem oil, if needed.
  5. Support: For taller varieties, stake the plants to protect them from Charleston’s coastal winds.

Fragrant and Beautiful Mosquito Repellent Garden: “A Scarborough Fair!”

There is a long history to the lyrically famous ingredients of “Parsley, Sage, Rosemary and Thyme.” Initially, they appeared in an old English folk song about a Medieval festival, “Scarborough Fair,” in Yorkshire, England.  Several centuries later, in the mid 1960’s, Simon & Garfunkel made them popular once again. Prior to the folk hit version of the lyrics, they were also sung as “Savory Sage, Rosemary and Thyme.”

Sage (Salvia officinalis), Rosemary (Rosmarinus officinalis), Thyme (Thymus vulgaris)

Though the jury is still out for what purpose the original herbal mixture was intended, these three plants combined with a few others, can be used to create an intensely fragrant and beautiful space that not only delights “true lovers” of gardens, but repels mosquitos and other annoying pests. Perhaps the organizers of Scarborough Fair wanted to ensure a bug-free festival experience!

The secret is in the scent. Mosquitos and other biting insects seek out their victims by the gases and odors they emit. Sweat and exhaled carbon dioxide are just some of the enticing elements that make us so attractive to Mosquitos, No-see-ums and other biting pests. Creating a garden space with plants capable of giving off scents strong enough to interfere with the insects’ receptors can make it more pleasant for us to spend time out of doors and more difficult for them to enjoy a free lunch!

Along with the melodic trio mentioned above, a beautiful and fragrant mosquito repelling garden can also include Lemon Grass (Cymbopogon citratus), Citronella grass (C. nardus), Lemon Balm (Melissa officinalis), Basil (Ocimum basilicum), Catnip (Nepeta cataria), Lavender (Lavendula officinalis), Bee Balm (Monarda spp.), Floss Flower (Ageratum), Marigold (Calendula officinalis), Mint (Mentha spp.), Lantana (Lantana camara),  Fennel (Foeniculum vulgare), Eucalyptus (Eucalyptus cinerea), (E. globulus subsp. Bicostata), (E. vernicosa).

A strong and concentrated amount of the oils present in these plants can help throw these annoying critters off of your scent. Burning or crushing some of these leaves can create an eco-friendly repellent. During an outdoor BBQ, toss a bit of Sage, Rosemary and Lemon Thyme on the grill. While working in the garden, pluck some lavender or mint foliage, crush them together and apply the oil. (Just be aware of any skin allergies before use.)

The best deterrent is to eliminate the environment that benefits the breeding of these insects. Finding and removing sources of standing water is an important first step. Mosquitos can lay 100 eggs at a time. They look for moist conditions that will trigger the growth of the larvae. Potted plants and containers, stagnant ponds, drainage ditches, and abandoned swimming pools are just a few of the common breeding grounds where mosquito and other annoying larvae thrive. Using products containing Pyrethrin (pesticides found naturally in chrysanthemum flowers) or Bacillus thuringiensis (Bt. a bacterium found naturally in soil) are some eco-friendly ways of mitigating mosquito proliferation. Pyrethrins come in a liquid concentrate or premixed liquid form that can be sprayed directly on plants and shrubs. Among other forms, Bt is available in a product known as “Mosquito Dunks” that can be submerged in water. It destroys mosquito larvae before they can become biting adults. It does not harm people, pets, wildlife or fish.

Lyrics, as published by Frank Kidson, 1891:

“O, where are you going?” “To Scarborough fair,”

    Savoury sage, rosemary, and thyme;

“Remember me to a lass who lives there,

    For once she was a true love of mine.

“And tell her to make me a cambric shirt,

    Savoury sage, rosemary, and thyme,

Without any seam or needlework,

    And then she shall be a true love of mine.

“And tell her to wash it in yonder dry well,

    Savoury sage, rosemary, and thyme,

Where no water sprung, nor a drop of rain fell,

    And then she shall be a true love of mine.”[6]

Pre-emergent Application to Keep your Lawn Weed Free and Grass Green

It is time to start planning for spring weed prevention and grass greening up. The advantage of applying a pre-emergent herbicide is that it is able to prevent the seeds of those pesky spring weeds from even getting started. Remember, DO NOT APPLY A PRE-EMERGENT HERBICIDE IF YOU PLAN TO SEED YOUR YARD. It will have the same effect on grass seed! In general terms the times to apply pre-emergent herbicides are Valentine’s Day to prevent spring weeds, Memorial Day to prevent summer weeds and Labor Day to prevent winter weeds.

Spring application is most effective when the pre-emergent is applied as daytime temperatures reach 65-70° F for 4 consecutive days. That is usually between February 14th and March 1st.  Herbicide should then be watered in with half an inch (½”) of water to activate. The type of pre-emergent to use should be based on what type of weeds you have. Scotts Halts works very well on crabgrass and other grassy weeds. The 10 lbs bag will cover up to 5000 square feet and should not be applied to landscaped beds. By the way, the Scotts product is now called WeedEx with Halts.  Hi-Yield Turf & Ornamental Weed & Grass Stopper works well to prevent many broadleaf and grassy weeds, including crabgrass, and can be used on landscape plants listed on the label. The 12 lbs bag will cover up to 3500 sq. ft. An organic option would be Espoma Weed Preventer made from corn gluten. A 25 lbs bag covers 1200 square feet. It has some nitrogen as a fertilizer component in it too. We have several other options, bring in pictures or samples of the problems you are dealing with when you visit Hyams Garden Center diagnostic desk and we’ll figure out the best course of action.

As you move into late March early April, you will see the warm season grasses start to green up. Please resist the urge to apply a weed and feed at that time, as the post emergent component and the high nitrogen levels could easily burn the new growth. After you have cut the grass a couple of times an application of a slow release lawn fertilizer such as Ferti-lome 15-0-15 Centipede Lawn Fertilizer will help the grass to green up slowly, not burning the new growth or contributing to fungus problems. The 20 lbs bag will fertilize up to 5000 square feet. Once fully greened up and actively growing, you can apply a weed and feed such as Ferti-lome 15-0-4, St. Augustine Weed and Feed or Bayer 35-0-3 3 in 1 Weed and Feed for your Memorial Day application. Be sure to read the labels of all these products and follow the direction carefully.
