Hedera colchica ‘Sulphur Heart’  VARIEGATED PERSIAN IVY Large leaf ivy with thick curled heart shaped leaves. A bright yellow center and veining accent the light and dark green leaf colors. Clings to any rough textured surface as long as the aerial roots can get a grip. Long lasting as a variegated cut green in flower arrangements. Hedera helix IVY Use as a ground cover where it will stabilize the soil, or as a climbing vine. Vigorous in the shade and the best growth occurs in moist soils but this ivy is tough and adaptable. Will climb almost any vertical surface. Many cultivars are available and the variegated forms tend to be less cold hardy. Severe winters and exposed sites can cause the foliage to burn and the leaves to drop. Prune or trim to control growth at any time of the year.

Helenium SNEEZEWEED Long blooming native plants that have been extensively hybridized in Europe. Falsely accused of making one sneeze, common ragweed is the real culprit having a similar bloom time. Appreciates moist soil and will tolerate poorly drained soils. Good cut flowers are also attractive to butterflies. Shorter cultivars reduce the need for staking. Basically pest free.

Helianthus salicifolius WILLOWLEAF SUNFLOWER This perennial sunflower provides a stunning mass of color for fall gardens, at a manageable height. Leaves are narrow and willowlike, plants are upright and self supporting. Prefers average well drained soils. These yellow flowers with dark brown eyes make a nice cut flower. Birds enjoy the seeds.

Helleborus HELLEBORE Large, hand like leaves break foliage patterns beautifully under deciduous trees, shrubs and shady spots, providing handsome foliage for most of the year. Their nodding cup shaped blooms signify the start of the long awaited growing season and are very durable, yet delicate in appearance. Prefer moist, fertile garden soil that is not too wet. H. foetidus STINKING HELLEBORE produces evergreen leaves in a fanlike arrangement with 7-10 toothed leaflets. The word "foetidus" meaning bad smelling, refers to the foliage when bruised or broken only. This star of my winter garden will start to bloom in late autumn and then hold midstream unaffected by the winter, only to continue the bloom cycle in the spring, an amazing thing to witness every year! H. orientalis LENTEN ROSE grows abundant glossy green basal leaves, with a finely toothed outline in a 7-9 leaflet span. H. argutifolius CORSICAN HELLEBORE With thick foliage and sturdy stems this hellebore offers a generous display of green flowers that, over time, open completely flat. Young foliage is green, maturing to a blue grey and complemented with silvery veination. Each leaf is comprised of 3 leaflets displaying widely spaced, finely toothed edges.

Hemerocallis DAYLILY Thrive in a wide range of soils as long as drainage is adequate, but are at their best in deep, moist, fertile loam. Practically indestructible plants used in borders, as a ground cover, edging and specimen plants. Arching leaves are bright green and grassy. Highly useful plants for exciting shows in successive blooming design.
A word on ploidy- Sometimes you see Daylilies being referred to as a tetraploid.  Normally Hemerocallis is diploid, meaning they have two sets of chromosomes in their cells, one set from each parent, humans, too, have a diploid number of chromosomes in their cells.  Tetraploidy is having 4 sets of chromosomes in each cell, 2 sets from each parent.  So, how and why?  The how could be anything from a naturally occurring phenomenon to gamma radiation, but with Daylilies it is most often done with the chemical colchicine.  When applied to the plant it causes a disruption in Meiosis (division of cells for sexual reproduction) that doubles the set of chromosomes.  As for the why, tetraploids normally have larger flowers with brighter saturated colors and flowering is often prolonged.  Flower scapes and leaves are sturdier and the overall habit is often more robust.  For plant breeders the increased number of chromosomes offer better control of plant characteristics.

Hepatica acutilobaLIVERLEAF Ushering in spring with bouquets of blue, violet and pink flowers, this charming little native is a great addition to the sunnier woodland garden.  Due to its small stature plants show best when planted in mass or among the rock garden.  Hepaticas native habitat consists of rich wooded soils often around limestone.

Heptacodium miconioides SEVEN-SON FLOWER Originally collected by Ernest Wilson in 1907 from the mountains of southern China, it was somewhat forgotten until a recent expedition back into that area in the 1980’s.  Seed’s of this small tree were collected and it is now becoming readily available in cultivation.  Offering multiple seasons of interest.  In late summer, fragrant, white, jasmine like flowers branch in terminal clusters of seven.  After a stunning floral display berries are formed surrounded by cherry red petallike leaves (calyces).  In winter, exfoliating bark reveals a light nutmeg brown inner bark.  Heptacodium has been called “The Crepe Myrtle of the North”.

Heuchera ALUM ROOT These plants have woody roots that slowly spread to form dense clumps of rounded leaves. Useful in the border or woodland garden and as an edging or ground cover. Numerous wiry stems arise holding tiny bell shaped flowers. Various kinds are particularly enjoyed as cut flowers. Many forms are available having evergreen leaves that may be silver mottled, marbled or beautifully tinted gray silver or bronze purple. Thrive in moist fertile soil. H. 'Palace Purple' has deep purple foliage in spring and fall, fading in hot summers to bronze green.

The native H. moscheutos (palustris) MARSH MALLOW is common in NJ wetlands, with large 6 in. flowers mixing the three colors on plants that grow in clumps. These Hibiscus all prefer wet sites and rich soil, but will thrive in average moist gardens as well.

Hosta PLANTAIN LILY Extremely useful and long-lived plants, growing best in deep, moisture retentive soil containing humus. Foliage of diverse color and character is generally larger when grown in denser shade. When grown in a brighter position, plants tend to be a bit more compact and flower freely, but require more moisture. Semi-shade to full bright shade is preferred, and siting as such will help preserve the color of blue leafed hostas. The blue coloring comes from a waxy coating that fades away over the season with exposure to rain, heat and sun. A wide range of heights, color, variegations, leaf shape and texture are available to accent that specific area, including flower color and sometimes fragrance.

Hydrangea arborescens ‘Annabelle’ SMOOTH HYDRANGEA Flowers on the new growth of current season. Native hardy to zone 3. If previous season stems are cut to the ground, the new shoots produce larger flowers up to 10 or 12 inches in diameter. Hydrangea macrophylla BIG LEAF HYDRANGEA Blue or pink colors depend on the amount of available aluminum in the soil or media. High acidity (low ph) solubilizes aluminum result in blue flowers low acidity (high ph) or alkaline conditions tie up aluminum in insoluble forms resulting in pink flowers. Hydrangea paniculata ‘Limelight’ PANICLE HYDRANGEA Easy to grow. Flowers on the current seasons growth. (with the exception of the cultivar ‘Praecox’) Best pruned in late winter but before leaf emergence to remove old flowers and to improve and open the plant structure. Quite adaptable to most soil conditions as long as drainage is good. Hydrangea quercifolia OAKLEAF HYDRANGEA A beautiful native shrub offering handsome leaves and flowers, good fall color and exfoliating bark.

Hypericum calycinum ST. JOHN'S WORT A semi-evergreen sub shrub. Somewhat slow to establish but in time makes a very solid, woody cover. Adaptable to various fertile to infertile soils, but best in fertile loam soil with average moisture conditions. H. calycinum is a fine ground cover with light green smooth leaves above, and glaucous beneath. Especially useful to break foliage patterns and bright flowers bring an extra surprise, decorating an already beautiful cover. Hypericum a. 'Albury Purple' has larger green leaves with burgundy purple leaf tips that compliment the yellow flowers. As the season progresses, the attractive ripening fruit extends the interest considerably. Should be cut back hard in spring.
