Hemerocallis ‘Pearl Cove’

We don’t grow many Day lilies. To be honest they are kind of done. But we have chosen a half dozen that we think add a lot to a garden. This variety is not only subtly beautiful with complex soft colors, it will often re-bloom through the summer if given ideal conditions. What are those? Rich, moisture retentive soil with regular, dependable irrigation through the hot months. The 3″ flowers have hints of cream, golden yellow, soft pink and even apricot. Delicious- as they are edible too. A long lived perennial that forms an expanding clump to 2′ tall and more than two feet wide. Full sun to the very lightest shade. Loved by butterflies. A good looking, long lived, trouble free plant. Completely deciduous in winter.

Hemerocallis ‘Betty’s Pick’

One thing we know about Betty, she was obviously something of a size queen. We LOVE this unusual dwarf daylily that exhibits HUGE outsized startlingly beautiful flowers for 4-6 weeks early to mid summer. To just 14″ tall the outrageous yellow/chartreuse and mauve flower explode open and stretch to 6″ across. Its unbelievable . Forms a spreading clump with mid-green arching strappy leaves. Screams to be at the front of a border or where the context of the huge flowers can be appreciated. Full sun to light shade and rich, moisture retentive soil. Regular water through the bloom period enhances the already outrageous display. Completely winter deciduous.

Hibiscus syriacus ‘Diana’

Bred and released from the National Arboretum this is perhaps one of the very best hardy Hibiscus shrubs for our climate. Enormous pure white flowers up to 4″ across  begin in July and repeat until October. This cultivar was selected not only for its blooming power but for its lack of ugly seed heads. To 8′ tall by 4′ wide in 6 years. Full sun and deep but infrequent irrigation in summer improves performance. Moderately fast growing deciduous shrub that will handle quite a bit of drought once established. Fall color is yellow to non-existent. A very showy shrub at a great time of the year. Opulent large tropical like blossoms. Shrub borders, with Crape Myrtles whose bloom is simultaneous. This superior variety can be difficult to locate. We’re going to change that.

Sphaeralcea ‘Hot Pink’

Globe Mallow. Fun and easy to grow perennial that behaves like a sub-shrub. Semi woody wands of very silvery small maple shaped leaves wave to 3′ tall. Lining these silver stems are bowl shaped hot pink flowers. They begin as early as late May and continue unabated for months. As time goes on this perennial for dry, hot locations with good drainage becomes a showy hot pink mass of blooms. Excellent on hot slopes with light but consistent summer water. Very drought adapted but light water appears to improve the performance. Loved by bees, butterflies and other pollinators. By autumn this 3′ x 3′ shrub should be left intact to over winter. In spring when new growth is breaking from the base it may be cut back hard and recovery to bloom is rapid with the onset of warmer weather. Cold hardier if given very good drainage. As far as I can surmise it will take temperatures down to about 10ºF.  A selection or possible hybrid from two southwestern globe mallows.

Cuphea cyanea var. subhirtella

This plant has been a real surprise. Most Cupheas are decidedly tender to cold in our climate, however, this variety soars above the rest. Its been a long term reliable perennial for us. Perhaps just a smidge hardier than the species. This charming little bat flower delights with multicolor flowers- tubular and shades of pink and yellow. The petals that serve as the bats ears are maroon. Wonderful long blooming plant- flowers continuously all summer to autumn. To 1′ tall and as wide. As a perennial it excels in rich, well drained soil with regular summer water in full sun. Just when you think it won’t return in spring it quickly arrives with warm weather and commences blooming almost straight away. Loved by hummingbirds, butterflies and pollinators in general. Treat it well – water and establish and mulch for the first winter. As an annual it is wonderful as a continuous flowering container subject. Native to Mexico.

Erigeron glaucus ‘Bountiful’

Such a long, long, blooming tough and dependable native this forgiving perennial outshine all other cultivars in the  size of each flower. The many rows of glowing lavender petals that characterize this fabulous perennial outline nearly 2″ wide flowers. They begin in earnest in late May and proceed unabated until early autumn. If the flowers become tired or scorched simply cut it back and wham! You’re quickly back in business. Adaptable to many soil types and will subsist on only natural rainfall but occasional deep soaks in summer reaps rewards. To 10″ tall forming around round perennial to 18″ wide. Full sun,  to very light shade. Pollinator masterpiece. Oregon native Plant.

Agastache ‘Berry Princess’

We believe this to be a cross inheriting some of the coloration of A. auranticus as well as A. cana. To 28″ tall this clump forming, everblooming perennial brings bright red buds that open to purple flowers. The colorful combination lasts all summer into autumn. New flowers are born on the same spikes so do not remove. Moderate consistent water through the first summer to establish. Double dig soil to incorporate oxygen into the soil and aid in irrigation to the roots. Established plants get by with a little less. Loved by hummers and  pretty decent cutfower as well. Full all day sun for best performance, will not be quite as floriferous in part shade. Sweetly scented foliage is an extra benefit. To 18″ wide and slowly increasing. Excellent on berms as well as slopes. Mulch in fall.  Small rosette of winter foliage is protected by the previous years defunct stems. Prune these away after all threat of a hard freeze has passed.

Cerinthe major var. purpurescens

Cool mediterranean annual that we love for its complex combination of bract and flower colors. To 14″ tall the nodding bell shaped flowers are blue with a white ring around the lip. The base of these flowers is yellow. Large bracts protect the flowers and turn from blue green to shades of indigo as they mature. A cool season annual that often self sows. These seedlings cruise through winter without much of a hitch and are up and blooming by mid spring. By the heat of july they quickly die setting profuse seed and disappearing. Light additional water besides rainfall will lengthen the show. Seedlings appear where they are happy- this can even be the cracks in the sidewalk. Seedlings are easy to spot and move or dispatch if unwanted. Nice in spring containers. Plant with early blooming Euphorbias for a real picture of yellow and blue contrast.

Pittosporum tenuifolium ‘Garnettii’

One of the cold hardiest selections of this species native to New Zealand. This stunning evergreen shrub of unknown origin shines in the garden with round leaves edged in white with an interior of soft green. And these bright leaves are held on dramatic black stems. In spring small black to maroon flowers decorate the leaf axils. Moderately fast growing pyramidal shrub to 8′ tall x 4 wide in 7 years- and gradually larger. In winter the leaves become even more colorful taking on bright pink tints. Requires a somewhat protected location- avoid exposure to subfreezing winds directly. Best sited with protection from east winds. Full sun to high over head shade. Accepts regular summer water which will increase the rate of growth- but established plants are remarkably summer drought tolerant. Excellent cut foliage for arrangements. A luminous shrub that virtually glows in the landscape. Cold damage begins at about 10ºF- but spring recovery is rapid.  Limited quantities.

Pittosporum tobira ‘Variegata’

An old shrub that deserves a new lease on life. Venerable old specimens are found throughout Portland proving its durability over time. The rounded evergreen leaves are edged in cream with an interior of soft sage green. In May/June masses of small white  deliciously citrus-blossom scented flowers perfume a wide area. Not as dense or fast growing as the species- and prone to losing older leaves in colder than normal winters- so it can have an open appearance. Excellent evergreen specimen shrub for a hot location. A south or west facing wall is ideal and it can withstand the most withering afternoon heat. Slow growing to 6′ x 6′ in 10 years. Very drought adapted when established, but it will happily take regular summer water. The foliage is so fetching that it is often seen for sale as cut material in bouquets. It lasts for several weeks in a vase. Full sun to quite a bit of shade. Nice foundation shrub. Established shrubs are cold hardy to about 5ºF. Avoid exposure to strong subfreezing winds. Easy and pretty urban plant.
