Although Emerald Gold can achieve somewhat larger dimensions by maturity (if left unpruned), these shrubs are most often pruned to be kept compact. With their low-mounding habit, Emerald Gold can function as a groundcover as shown in our garden.
Grow them in well-drained soils either in the sun or shade, however they will produce their best color display if planted in full sun.
This Clematis has enormous flowers, 8 to 9 inches across, which completely cover the vines from May through frost. Its vivid colors make the blossoms look tropical, but clematis is tough and hardy and is nearly carefree once established.
It requires a support and climbs 8 to 12 feet. Like all other Clematis it does best when planted in full sun with roots shaded.
You can find it growing on the archway between the Vegetable and Fountain Gardens.
Chocolate Chip Ajuga - This low growing ground cover offers both fetching foliage and showy flowers. Its narrow leaves are enticing shades of plum and chestnut. When not in bloom, Chocolate Chip Ajuga may be walked on with no fear of damaging its foliage.
Three inch spikes of frothy blue blossoms are produced in spring and sometimes reoccur in milder climates. Set against the darker leaves, these blue flowers really pop. This is a fast growing favorite that spreads rapidly by runners and makes a mat of dense, dark green foliage.
Chocolate Chip is a dwarf form that grows just 2-3 inches high but spreads up to 3 feet wide. Count on it to crowd out those pesky weeds. This plant will adapt to almost any garden or landscape locale.
This Japanese maple has a round shape with a height and spread of about 20 feet, making it nicely suited to residential landscapes. Its popularity is due mostly to the leaves, which stay red for most of the summer.
Leaves turn greenish red during hot weather in the southern part of its range. The multiple trunks are muscular-looking, picturesque, grey and show nicely when lighted at night. Fall color is reddish and less striking than other Japanese maples. Lower foliage branches can be thinned to display the attractive bark and trunk structure.

This plant has proven to be a showstopper. This alluring plant cries out for attention with its beautiful spring flower display, gray-blue summer foliage and exceptional, rich-red leaves in fall.
Of all its favorable attributes, the striking blue hue is what really sets this Fothergilla apart. It's a winner in landscapes and provides a sharp color contrast to companion plants, particularly those with golden foliage. 'Blue Shadow' forms a dense network of angular stems.
It's an upright grower that broadens with age, eventually becoming 5-6 feet high and wide. It is tolerant of both full sun and partial shade. A semi-shade location will result in a more open habit.
Like other Fothergilla, 'Blue Shadow' is native to the Southeast and has no known disease or insect susceptibilities and thrives in somewhat acidic soil with good moisture and adequate drainage.
In April to early May, 'Blue Shadow' will dazzle bystanders with honey-scented, bottlebrush flowers. Outstanding blue leaves soon follow. In mid-October to late November, fall colors appear. Rich red dominates and is often accompanied by shades of orange and dark yellow, so this plant has seasonal interest galore.
You can find this wonderful plant in full spring bloom in our Boulder Garden and as a container plant near the greenhouse.
This Redbud is highly drought tolerant once established and grows well in all areas within its hardiness range of 6B thru 9A. The deep pink to red flowers appear in profusion up and down the tree limbs in springtime, well before the leaves begin to emerge, creating probably one of the best Redbud displays. It also has a subdued red-burgundy fall color. As a young tree it will benefit from some training and pruning to form an upright, more uniform crown.
You can find it across the path at the top of the Boulder Garden next to the fence.
Fantastic new Weeping Redbud variety with dramatic foliage color. Ruby Falls blooms prolifically in early spring when bunches of tiny, hot pink, rose-purple, pea-like flowers accentuate the bare, pendulous branches and trunks for 2-3 weeks before the foliage emerges.
As the year progresses rich ruby-purple leaves appear, gradually changing to deep green during the summer. In the fall the foliage changes to bright yellow. With its unique and elegant weeping habit, this plant is perfect for small gardens, lawns or woodland gardens. This tree can grow up to 6' with a 4' spread. It’s the first weeping purple redbud developed. Minimal pruning is needed.
You can find this tree in our entry garden next to the steps leading to our annual display beds.
