Eryngium

Sea Holly

From its leathery lobed leaves to the spiny decorative bracts that host the flower, the dynamic Sea Holly has a sense of movement that is up and out. Excellent in fresh or dried arrangements, the flowers are borne on tall branching stems, and the terminal blooms hold their color while lateral flowers develop, until the entire stem is covered with mature blossoms. Eryngiums love sharp-draining soil in the open sun, and are an arresting ad­dition to the mixed border, especially when planted amidst Rudbeckia, Achillea and grasses.

Feathery-fine ferns, Refresh your summer border, Summer Shipping!

Characterized by delicate-looking fronds...

the deer-proof ferns, which are featured above, unfurl spritely new fiddleheads every spring. All are deciduous save for the lustrous Polystichum, otherwise known as Tassel Fern. Varying shades of green, metallic silver, russet, bronze and burgundy imbue their artful foliage. Second-to-none for shady alcoves, these easy-care perennials can be planted as specimens or grouped in shade gardens, mixed borders and woodland settings. Their filigree-fine features lend sophisticated accents to patio containers or cut arrangements. Ferns will flourish in cool , well-drained moist nooks enriched with compost or well-rotted manure.  

Refresh your summer plantings...

During the month of July, gardeners sometimes wonder how they can perk up their summer gardens. Sunshine-hued blooms, golden leaves and crisp white flowers lend lively accents. They can be sprinkled amid a mixed border, perennial bed or other plantings, melding well with flowers that include a broad color spectrum from blue-violet to purple and lilac, as well as clear pink and darker rose hues.  

Apart from adding more plants, there are a few simple maintenance techniques that will help your garden maintain a fresh appearance during the summer. The addition of a chipped-bark mulch or well-rotted compost early in the season, not only reduces water requirements throughout the warmer months, but promotes vigorous growth and peppy-looking foliage. Many perennials, such as Nepetas and Geraniums, can be trimmed in June or July. This midseason cut back ensures a tidy stature and more blooms, often all the way ‘til frost.

We hope some of the plants in this newsletter spark some interest and beckon you to dig them into that empty spot in your garden.
