I have been madly photographing for our Florafind database, and as a result, I have managed to capture many new plants added to the garden over the last year. What follows (in no particular order) are but a few of my favorites from the class of 2011. Bill Cullina (see notes below gallery)
Triosteum aurantiacum ‘Red-leaved Form’ (Wild Coffee)
Wild Coffee is an unusual woodland perennial in the honeysuckle family from the eastern US. We got this form from Enchanter’s Garden. The leaves emerge burgundy red and remain that way until well after the small red flowers fade in late spring. Orange berries develop in the leaf axils late in the season. Look for on the north side of the Bosarge Family Education Center. An image of the curious red flowers appears in the Spring Has Sprung post.
Polygonatum pumilum (Small Whorled Solomon’s Seal)
We are building a large collection of Solomon’s Seal species and this is one of the cutest in flower. Six to eight inch tall stems support whorls of three leaves from which emerge relatively large, pink flowers. It keys out most closely to this species in Flora of China.
Polygonatum kingianum (Red-flowered Solomon’s Seal)
There are probably at least three different species being sold under the name Polygonatum kingianum. According to Polygonatum authority Aaron Floden, this may be actually P. huanum. In any case it is a very large, arching plant with very colorful flowers. Look for it near the Pavilion in the Lerner Garden of the Five Senses.
Plectranthus kameba (Hardy Plectranthus)
Though primarily a tropical genus, this hardy herbaceous member from Japan becomes a five by five foot mass bedecked in violet flowers in October. It is a startlingly impressive specimen for such a late date! It grows along the cat fence in the Bibby and Harold Alfond Children’s Garden
Paeonia ‘Pastel Splendor’ (ITOH Peony Hybrid)
We are trialing a number of intersectional or ITOH peony hybrids. These crosses between herbaceous and tree peonies have lovely foliage and strong stems that do not need staking. Look for this selection Near the Whales in the Alfond Children’s Garden
Lilium ‘Conca D’Or, a.k.a. ‘Golden Stargazer’ (Golden Oriental Lily)
When this spectacular lily flowers near the entrance to the Lerner Garden of the Five Senses in July, there is no finer place to be in the Gardens. The flowers are six inches across and heavily scented. Wow!
Leucosceptrum stellipilum (Japanese Shrub Mint)
This unusual perennial resembles a hydrangea during the summer, but in early fall, knobby spikes gradually develop at the stem tips and finally burst into flower in mid-October. Still in our nursery, propagator Sharmon Provan is working to increase our number so we can establish it in the garden.
Iris cristata ‘Dick Redfield’ (Crested Iris)
Named for my late friend and mentor Dick Redfield from eastern Connecticut, this is the prettiest crested iris I have grown. Iris flowers are typically composed of three standards (upright tepals) and three falls (lower tepals, often bearing a wrinkled crest. ‘Dick Redfield’ produces an extra set of falls, do the flowers have symmetry and patterning that is uniquely beautiful.
Hydrangea paniculata ‘Quick Fire’ (Panicle Hydrangea)
Panicle hydrangeas are hardy and durable flowering shrubs. The old cultivar ‘Pee Gee’ is a fixture in dooryards, parks, and cemeteries throughout Maine. In recent years a flurry of new selections has hit the garden centers, and we feature a number of these in the Gardens. Most of these bloom in late summer, but ‘Quick Fire’ is unique in that it begins blooming a full month early in July. The colorful bracts begin white and fade to light then dark pink as the season goes on. Look for it near the rill between the Slater forest pond and the Lerner Garden of the Five Senses. Though Hydrangea paniculata will naturally grow into a small tree, we cut ours back to 12-18 inches in late March to keep the plants manageable and to encourage better bloom.
Hamamelis × intermedia ‘Birgit’ (‘Birgit’ Witchhazel)
Of the dozen hybrid witchhazels in our collection, perhaps the most distinctive is ‘Brigit.’ Located near the group entrance to the Alfond Children’s Garden, this small tree flowers in March, unfurling its ruby red blossoms on warm days and furling them when the weather turns cold.
Epimedium simplicifolium (Single-leaved Barrenwort)
As with Solomon’s Seals we are developing a large collection of barrenworts. From the forty or so accessions in our collection, this is one of my favorites. The large evergreen leaves make this foot-tall woodland plant an excellent groundcover, and the large, garnet and white flowers are a welcome surprise in early spring.
Disporum cantoniense (Pink Chinese Fairybells)
I just wrote about the pink-flowered form of pink Chinese fairybells from an upcoming issue of horticulture magazine. Another woodland perennial from Central China and south, this species is related to a group of North American wildflowers that taxonomists have moved from Disporum into the genus Prosartes. It is an elegant plant that you can find growing with yellow lady-slipper orchids in the Woodland Garden.
Baptisia × bicolor ‘Starlite’ (Starlite False Indigo)
The Chicago Botanic Garden has been actively breeding our native false indigos for a decade or so. This introduction is a hybrid between large blue false indigo (Baptisia australis) and the demure Baptisia bracteata. As a result it is much more compact than most false indigos – a good thing as typical Baptisia australis grow three feet tall by four feet wide.
Alstroemeria ‘Freedom’ (Freedom Peruvian Lily)
One of a series of winter-hardy Peruvian Lilies from Dr. Mark Bridgen at Cornell University, this light pink perennial began blooming in June and is still in flower now in mid-November behind the drying shed in the Alfond Children’s Garden!
Abies numidica (Algerian Fir)
The final mention is one of our most asked about trees. Also in the Alfond Children’s Garden near the whale terrace, this prehistoric-looking conifer hails improbably from the high mountains but looks very much at home in conifer-rich Coastal Maine. Ruby-colored pollen cones poke out from the needles in spring.
