Plant List

Ajuga Repens ‘Caitlin’s Giant’
(8”, spreading ground cover, burgundy leaves with blue flowers - early summer)

Angelica Gigas
(3-6+’ x 3’, clump forming biennial or short lived perennial which self-sows freely, 
deep purple bracketed umbels 3-5” across late summer. A favorite!)

Aster Tataricus
(8+‘, lavender blue daisy flowers in fall, spreads stoliniferiously,
one of the late flowering perennials.)



Convallaria Majalis Rosea
(8”, pink Lily-of-the-Valley, spreads quickly)


Red/Yellow Daylily
The daylily is often called "the perfect perennial," due to its dazzling colors, ability to tolerate drought, capability to thrive in many zones, and requiring very little care. Daylilies thrive in full sun, although certain daylilies require partial shade, depending on color. Lighter shades, such as yellow, pink, and pastels require the sun to bring out all of their color. Darker daylilies, such as some red and purple flowers, need shade because their darker colors absorb heat.  Today, daylilies come in an assortment of shades, whereas they formerly were only available in yellow, pink, fulvous, and rosy-fulvous. Now the flowers can be found in many shades of yellow, pink, red, purple, and melon. The only shades daylilies are not available in are pure blue and pure white, which hybridizers are working on.  Daylilies have a relatively short blooming period, depending on the type of daylily. There are a variety of different daylilies; some of which will bloom in early spring, while other wait until the summer or even fall. Most daylilies bloom for one to five weeks, although there is a type of daylily known as a re-bloomer, which will bloom twice in one season.

Digitalis Lutea
(24-30” x 12-24”, clump forming perennial Foxglove, pale yellow flowers, self-sows)


Green Eyed Susan

Rudbeckia hirta ‘Irish Eyes’ – ‘Irish Eyes’ lives up to its name with large single golden-yellow daisy-like blooms with a prominent green central cone. It has long sturdy stems and makes a good cut flower. As with all Gloriosa Daisies, these are short-lived perennials that many treat as annuals, although they will often self-seed. Grows 28-32″ high by 12-18″ wide. Hardy to zone 5.

Hemerocallis – Yellow Minor Daylily
(2’ - very light yellow flowers, spreads)

Hemerocallis Fulva Daylily
(30” double orange/red flowers, spreads)

 Hosta ‘Gold Edger’
(12-14” spreading gold foliage)

Hosta Plantiginea
(2-3’, clump forming, fragrant large white flowers in late summer,
light green foliage)

Hydrangea Petioles
(climbing Hydrangea, 50’, white flowers in early summer)

Hydrangea Quercifolia
 Oak leaf Hydrangea
(6’ x 8’, panicle of white flowers tinged pink, green leaves turn bronze/purple in autumn)

Lamium Maculatum
(8” x 3’, groundcover, pink flowers in late spring, spreads rapidly)

Lamium Maculatum ‘Beacon Silver’
(8” x 3’, groundcover, white flowers in late spring, spreads rapidly)


Obedient Plant

Obedient plants are easily established and very drought tolerant, forgiving plants. Although they prefer a moist, slightly acidic soil (5.5 - 6.3 pH), they’ll grow just fine in average - poor soil and spreading will be less of a problem. The biggest maintenance chore is keeping obedient plant from rampant spreading. Although the plants pull out easily enough, they seem to pop up everywhere. If you’re tempted to wait and let them flower, be sure to get out there before they go to seed. Long season gardeners can get a second flush of blooms if you deadhead the first flowers. Wait until spring to cut back old foliage.


Rubus Cockburnianus Aureum - Gold
(Ghost bramble, 4-5’ x 5-6’, silver prickly branches with gold leaves,
adds great texture in the border, in winter gold branches add interest,
cut to ground in spring)

Tansy (Tanacetum vulgare) is a perennial, herbaceous flowering plant of the aster family, native to temperate Europe and Asia. It has been introduced to other parts of the world and in some areas has become invasive. It is also known as Common Tansy, Bitter Buttons, Cow Bitter, Mugwort, or Golden Buttons.
