Hypericum

St. John´s Wort

<i>Hypericum androsaemum</i>

Native to western Europe and North Africa, this handsome species’ common name comes from toute-saine (heal-all) and refers to the many healing properties the plant was once supposed to possess. Interesting throughout the year, Tutsan is a cure-all for lightly shaded garden areas that need some brightening up. The wine-infused stems and deep green foliage contrast beautifully with cheerful golden yellow flowers in summer, and later with glossy red berries, which eventually turn black. The weight of the fruit causes the branches to arch, giving the plant a relaxed look and making it perfect for shrubby borders.

Tutsan also does well in the sun, planted with Lavenders. In late summer, its colors make a striking combination with Nepeta ‘Wild Cat’ and Buddleja ‘Ellen’s Blue’.

Blooms June–early August.

Size: 4' 0" high x 4' 0" wide.

Hardy to zone 6.

<i>Hypericum frondosum</i> ‘Sunburst’

In an ebullient “sunburst,” large 3 in. wide yellow petals cushion a spry central cluster of stamens that look like orange powder puffs. Dense stout branches plus oblong curvy leaves with soothing glaucous blue hues shape a compact round mound, revealing narrow reddish brown seed capsules through autumn and exfoliating purplish brown bark for winter appeal. Indigenous to our South-eastern limestone glades, this tailored semievergreen Hypericum can be massed or sited singularly in the mixed border where it triumphs over dry compacted soil and clay.

Blooms JuneľAugust

Size: 3' 0" – 4' 0" high x 3' 0" – 4' 0" wide.

Hardy to zone 5.

<i>Hypericum inodorum Hypearl™</i> ‘Compact Red’

Enticing butterflies, florists and all who behold it, this newly introduced compact shrub makes an ebullient statement. The resilient well-branched frame is characterized by sturdy, upright red-tinged stems plus comely medium green foliage that remains evergreen during mild winters. Hosting big round golden buds, decorative pale green calyces, flashy yellow starbursts of bloom with prominent stamens and plump, bright red berries, ‘Compact Red’ keeps us mesmerized for months. Acquiescent to sunny sites, it’s tailor-made for gardens short on space, mixed borders or patio containers.

Blooms June–mid September

Size: 18" – 2' 0" high x 18" – 2' 0" wide.

Hardy to zone 6.

Selected from our native American species, this exciting relatively new Danish cultivar premiers droves of small yet radiant yellow blooms with dense showy stamens, resembling miniature golden starbursts. Handsome bright green willow-shaped foliage and close-knit branches craft a neat bushy shrub that can be utilized as a low informal hedge or a stylish mounding ground cover. Small growing, sturdy and reliable, 'Gemo' delivers ample doses of flowery good cheer for months at a time followed by decorative pointed seed pods for added intrigue, while Geranium 'Walküre' and Aster divaricatus make worthy companions

Blooms June – September.

Size: 2' 0" – 3' 0" high x 2' 0" – 3' 0" wide.

Hardy to zone 5.

<i>Hypericum kouytchense</i> <i>Hypericum kouytchense</i>

This truly elegant Hypericum is covered with an abundance of large, bright yellow, pointed buds, followed by golden yellow flowers whose prominent long stamens seem to sparkle. Against a background of smooth blue-hued leaves, the bright red berries and starlike calyxes make a colorful late season display. Though deciduous elsewhere, along our coast the aromatic leaves fill the garden with their scent all year round.

Blooms June–September

Size: 3' 0" high x 2' 0" wide.

Hardy to zone 5.

Our featured plant: Athyrium niponicum var. pictum

Fresh Fern Fronds, Early-blooming Clematis, Marvelous March Foliage!

Fresh Fern Fronds...

Coveted for their artfully hewn fronds, the deciduous ferns featured above unfurl spritely new fiddleheads every spring. Varying shades of green, silver, henna and burgundy embellish their delicate-looking foliage. Tailor-made for shady nooks, these easily-grown flowerless perennials can be planted as specimens or en masse in shade gardens, mixed borders and woodland settings. They also lend exquisite feathered accents to patio containers or cut arrangements. Ferns flourish in cool moist well-drained locales enriched with compost or well-rotted manure. Feel free to peruse the Perennial section of our website for other Athyrium & Dryopteris species.

Exquisite early Clematis and marvelous March foliage...

Early-blooming Clematis herald spring with charm to spare. The armandii, alpina and montana Clematis species are generally the first to flower, with some even wafting sublime scents. Clematis armandii ‘Snowdrift’ and Clematis montana ‘Elizabeth’ sprout larger statures than the more petite Clematis alpina ‘Constance’ or ‘Jan Lindmark’, while all showcase beguiling blooms. These delightful vines can twine up arbors, trellises, walls or trees, offering vertical accents to the fresh flourish of head-turning foliage that blankets the beds beneath. The new growth featured in this newsletter was photographed this week in our garden and nursery.

All of us plant wranglers at the nursery, along with Boobah, our wee greeter and self-appointed nursery manager, and shy kitty, Parker, wish you countless happy hours digging in a garden of your own!
