A flower we need to share with everyone today is great for any sunny garden and areas with well-drained soil — ‘Big Blue’ Sea Holly. It’s drought and deer resistant, and grow as tall as three feet. Rabbits have appeared in much larger numbers this year in many of the Northern Virginia neighborhoods closer to DC, such as Cherrydale, and the Sea Holly is also rabbit resistant, so plant away everyone in NOVA! The silvery-blue flowers, which bloom in mid-summer, will take your breath away when they’re in full bloom. I pair my Sea Holly with Yarrow and Balloon Flower, pictured to the right, and they’re a trio of old friends I can’t wait to see in my home garden each year. Here’s a pic I took last year at home. When they’re in bloom with such wonderful colors and textures, I smile every time I see them, knowing that summer has arrived and will be staying around for a while.
Feed the Soil not the Plant. Plant health depends on healthy roots; healthy roots depend on healthy soil for air, water and nutrients delivered in forms plants can use. Soil that is rich in organic matter, aka compost, is rich in nutrients and in the life that makes those nutrients available to the plants (bacteria, worms, etc.) .
Ornamental plants in good soil usually do not need added fertilizer, and crop plants that do need extra food need less of it when it’s released slowly by friendly soil from things such as rock powders, kelp and green manures.
Water Fountains Make an Impact
It’s the second day of spring, and I’m thinking about water features! There’s nothing more inspiring than a well designed water feature blended into the natural environment to transform your garden into a destination. Let’s revisit an informative LOWE’s story by Jake Fowler from last year on water feature – water fountain trends that continue with full force into 2011.
GardenWise on Clay-Heavy Survivors
I work often in the clay heavy soil of Northern Virginia, which means I have the opportunity to share some of the most beautiful clay soil survivors, with blooms that will take your breath away. Blue Cornflower, a Kennedy favorite, and more are guaranteed to take your breath away. Below are some suggestions for those with clay-heavy soil, beginning with the irresistable Blue Cornflower.
• Blue Cornflower (Centaurea cyanus) These brilliant flowers are what memories are made of — rare among “blue” flowers as they are actually blue. They are delicately fragrant and drought tolerant. This flower has a lot of history — it’s the national flower of Estonia, was used in Pharaoh Tutankhamunand’s funeral wreath, and was President Kennedy’s favorite flower, worn by John Kennedy Jr. at his wedding to honor his father.
• Coneflower (Echinacea purpurea) These plants (herbs, actually) do very well in clay-heavy soil, are drought tolerant, and come in a variety of colors — the purple blooms will stop you in your tracks. They will break up soil as they grow, and are a favorite among those who practice herbal health as they have been known to boost the immune system.
• Daylily ( Hemerocallis) A must grow for anyone with clay-heavy soil, they do well in a wide range of soil conditions, come in a variety of wonderful colors, and are rugged. They also establish quickly, grow vigorously, and survive winters with little care.
• Liriope (Liriope muscari) With spikes of tiny violet-blue flowers, this grass-like plant is named after the nymph Liropie, mother of Narcissus. The plant is a member of the lily family, has dark green, ribbonlike foliage that recurves toward the ground, and does very well in soil with clay.
• Coreopsis Verticillata or Tickseed is a plant that is very tolerant of clay and its disc florets and ray florets are bright yellow that will make you smile from ear to ear, even on a not so sunny Fall day.
• Black Eyed Susan (Rudbeckia) is the Maryland state flower and a cheery perennial with bright yellow petals that surround black centers. It’s a striking flower that does very well in clay soil. Plant them en masse and enjoy the show!
• Shasta Daisy (Leucanthemum x superbum) With its classic daisy appearance of white petals around a yellow disc, they are attractive to bees and birds, and are drought-tolerant. They do well in clay-heavy soil and have cheery blooms.
The main maintenance task for hyacinths is called deadheading. Deadheading is simply pinching off old blooms to encourage new growth and transfer energy from making seeds. However, if you bought a self-sowing variety do not deadhead because you will lose the seeds.
The only other concerns for hyacinth bulbs is the occasional animal or rodent. If you notice missing bulbs and see signs of them being dug up, put up a barrier or fence to discourage intruders. If no signs of digging around missing bulbs are apparent then you may have a rodent problem. In this case you can protect the bulb by simply digging it up and putting a wire mesh in the hole to surround the bulb.

One of my all time favorites, and a recent top choice by GardenWise as a “must-have” Fall 2010 garden favorite, is Toad Lily (Tricyrtis.) As I earlier wrote, Toad Lily, with its beautiful orchid-like white flowers, purple flecks and graceful arching growth habit, compels anyone who gazes upon it to stop and take a closer look.
Better Homes & Gardens lists Toad Lily as one of their best perennials for shade, and I’m thrilled that more attention is pointed in this fantastic perennial’s directon. Make your shade explode with interest and color by adding the unforgetable beauty of Toad Lily.
