Want a colorful plant that blooms nonstop, attracts hummingbirds and never needs deadheading? Cuphea ‘David Verity’ , a selection of Cigar Plant, is a strong candidate. His charm can?t be captured in photographs, but that hasn?t stopped us from offering this cutting grown Cuphea for over a decade. Customers who have grown him once now can’t be without him.
Cuphea ‘David Verity’ grows to 18-24″ tall in a season, and likes an average to moist soil. He produces an endless supply of tubular orange flowers which keep the hummers busy. When temperatures get cool in late summer the foliage takes on a burgundy cast. The show carries on into the fall until a frost signals the season is over. We’ve combined ‘David’ in planters with Colocasia , Heuchera ‘Caramel‘, and dark leaved Ipomoea ‘Carolina Purple’ but many more combinations are possible. ‘David Verity’ provides constant color in the mixed border?…try him with dark leaved Heuchera villosa ‘Mocha’ and a hot colored cone flower such as ‘Tomato Soup’.
Sometimes your garden needs something tall, something blue. The abundant display of summer perennials laden with yellow daisy-like flowers begs for plant selections which offer dark contrast.
A “temperennial” here in zone 6, Tall Mexican Petunia won’t winter over outdoors for us, but it certainly will in zones 8-10. Still, we always make room for it in our gardens and also use it in container combinations where the tall 3-4′ purple stalks are clothed with narrow dark green purple tinted foliage. The continuous display of violet blue funnel shaped flowers extend on short stems from the leaf axils, and attract bees, butterflies and hummingbirds.
Ruellia ‘Purple Showers’ does enjoy evenly moist soil, and will even grow well along a pond?s edge or in low standing water, a situation that can be challenging. This does not mean it won?t grow in average soil conditions, for it will, but it does not want to fry. Southern nursery catalogs list Ruellia as an evergreen shrub. We suspect Ruellia may become territorial in warm climates, and should be planted where its vigor is an asset.
Japanese Clethra is waiting to be discovered. It is a plant for all seasons, boasting fragrant mid summer blossoms, yellow-orange to red fall foliage, and exfoliating bark in winter. If left unpruned it will grow as a multistemmed shrub or small tree, but we prefer to see it trained to a single leader, with lower limbs removed, so that the showy bark can be better appreciated.
We were smitten when our young plant came into bloom in July. Trios of sweetly scented white, 4-6″, twisting racemes will drip from the branches into August. The ovate serrated foliage, in a shade of dark green, really sets off the white blossoms. Fall color is also striking, ranging form yellow orange to deep red. Although Clethra barbinervis is fast growing, it seems to reach an ultimate height of 15-20′. It prefers a well drained, neutral or slightly acidic soil with adequate moisture. Clethra barbinervis grows well in partial shade, although it will tolerate and bloom abundantly in full sun, if watering needs are met. It can be cultivated in zones 5-8.
This easy care combination, which will be very happy in a spot that receives 4-6 hours of sun, includes Fuchsia ‘Gartenmeister’ complimented by multihued Calibrachoa ‘Tequila Sunrise’, Helichrysum ‘Limelight’ for light contrast, and Coleus ‘Dipt in Wine’ which picks up the colors of the other 3 candidates.
The Fuchsia and Calibrachoa (Million Bells) will lure hummingbirds and bloom endlessly. Should the Helichrysum (Licorice Plant) or Calibrachoa exceed their bounds with vigorous growth, just clip back. Plant this grouping in a good quality potting mix amended with compost or PlantTone, and Osmocote. In addition to fertilizer in the mix, we always recommend liquid feeding your containers every 1-2 weeks with a balanced plant food, such as Dyna Gro.
What a workhorse! This plant always looks terrific. Beloved by hummingbirds for his endless supply of long tubular salmon-red flowers, this upright bushy Fuchsia has handsome velvety dark green tinted purple bronze foliage. ‘Fuchsia Gartenmeister’, also known as ‘Gartenmeister Bonstedt’, in honor of it’s hybridizer, can reach a height of 2-3′, but can be pinched back if a shorter stature is desired, and can grow to a width of 18-24″ in one season.
We recommend growing ‘Gartenmeister’ in morning sun/afternoon shade, although we have grown this plant in a very sunny spot, where the flower supply was even more generous. Use a rich well drained soil and keep well watered. Fertilize container grown plants bi weekly. Plants are winter hardy in very warm climates (zone 10) but can be easily wintered over indoors, should you wish to keep plants for next year.
A classic combination for a sunny spot. We’ve combined our favorite Pelargonium sidoides with a new heat tolerant pale pink Marguerite, Argyranthemum ‘Pink Reflection’, silvery Centaurea gymnocarpa ‘Colchester White’ and Dichondra ‘Silver Falls’ and a compact selection of Gaura ‘Belize‘, with wine tinted foliage and wine/pink blossoms that dance on 18-24″ stems all summer.
This has been one of our favorite species “Geraniums” since we first offered it in 1997. Pelargonium sidoides is native to South Africa, and herbalists may be aware of it’s medicinal qualities for colds and bronchitis. We grow P. sidoides because it is superbly ornamental.
P. sidoides has attractive aromatic silvery gray foliage, and wiry branches with wispy clusters of dark wine colored blossoms, which are continuously produced all season. It does best in full sun, and forms tidy mounds 6-10″ tall with a spread of about 12-15″ in a season. It seems to perform admirably in both cool and hot summers, and, although only winter hardy to 20 degrees F, will easily winter over on a sunny window sill.
‘New Century’ is another tidy compact Rhododendron, with pale citron yellow blossoms. It has a very full foliage appearance due to the fact it holds its evergreen leaves for 3 years, rather than just 2 like most other rhodies. It grows to a well behaved 4′ x 4′ size and is quite hardy for a yellow form, (to minus 15F).
Grow this selection in a spot protected from drying winter winds. Morning suns and afternoon shade is ideal, but plants can take more sun if well irrigated during drier conditions. Like all Rhododendrons, ‘New Century’ appreciates a humus rich soil that remains moist but well drained.
Handsome violet blue blossoms in late April/early May distinguish this welcome addition to the mid spring garden. Introduced by Weston Nursery of Hopkinton MA, Rhododendron ‘Blue Baron’ falls into the lepidote group of Rhodies, which with a few exceptions, have smaller leaves, smaller more open trusses and prefer to grow in a more sunny spot. ‘Blue Baron’ has a compact habit,and is often listed as growing to 3-4′ in height and width, but at maturity can reach 6?. His fine textured elliptical foliage is glossy green in summer but takes on a bronzy cast in colder months.
Grow ‘Blue Baron’ in humus rich soil in full or part sun, and morning sun with some afternoon shade has proven ideal . He can tolerate a bit of wind, but we recommend using an anti-dessicant if winter winds are harsh. Like all Rhododendrons, ‘Blue Baron’ is shallow rooted, and will need irrigating during dry spells. Hardy to minus 10F.
Here on High Hill Road, much of the winter is spent searching for sources of the most promising new plants available in the horticultural market. We’re always optimistic, but we hold all newcomers to the standards set by great plants introduced in the past. Clematis macropetala ‘Lagoon’ introduced in 1958 by George Jackman and Son, has been on the market 52 years. Wow! This is comparable to the career of BB King and just as blue, but “the thrill is not gone”.
We planted Clematis m. ‘Lagoon’ at the base of a mop-headed silver leaved Capulin Cherry, Prunus salicifolia. That “bad-hair-day” cherry’s branches bowed down and insisted on giving ‘Lagoon’ a ride. As early as April, this vigorous clematis beguiles nursery visitors with blue blossoms as it adorns the branches of its silvery companion. “What is that blue flowering tree out near the parking area?” we are asked. You won’t need a tree to enjoy this 6 to 10′ vine, as it would do equally well climbing a trellis or arbor.
Clematis macropetala ‘Lagoon?’ needs little pruning. If it does get too rambunctious where it is planted, it can be pruned back in late June or July, after it has finished flowering, since it blooms early on old wood. Clematis like a slightly alkaline soil, so scratching in a handful of dolomitic limestone will keep it happy if your soils tend to be acidic. It is very hardy, growing well in USDA hardiness zones 3-8.
