Eryngium pandanifolium var. lesseauxii

Eryngium pandanifolium var. lesseauxii

Fun tall growing sea holly that may be impossible to pronounce but its easy to grow. Upright growing finely serrated or prickly leaves first make a low 2′ wide rosette then when it feels like it- usually the second year a big as spike rises with a divided scape and tons of off white prickly clover like flowers dot the stem tips. Its cool. This whole perennial is cool and its slightly hardier than the species. Very cool. Evergreen perennial for full sun and just about any well drained soil. Flowers rise to 5′ tall and with time there will be many spikes. Pollinators arrive in droves to pollinate this very unusual but architectural perennial from South America. High deer resistance.

Eryngium proteiflorum MX

This is a spectacular plant and Brandon collected the seed outside of Mexico City- at a very high elevation. Still we are not completely sure of its ultimate hardiness so I’m going to guess. Based on other Mexican and S. American Eryngium and considering this is a widely spread species I’ll say its good in rich amended soil that drains to about 10ºF. That is somewhat irrelevant as the flower on this member of the Apiaceae (Carrot family)is phenomenal. In May-August HUGER 6″ wide flowers with a protruding central cone are metallic silver and sage green Unbelievable. Full sun to light shade in a protected location. Worth protecting in a pot as it makes a stellar container plant. The unearthly flowers are held on vertical stems to 3′-4′. As a cut flower it is a wet dream, lasting weeks and drying too. Kind of prickly a low rosette of serrated evergreen leaves is permanent. Cut away the spent flower stalk when it fades and you  tire of it. Light, consistent water. Fantastic. Thank you to our great employee Brandon for capturing the seed.

Fargesia dracocephala ‘Long Leaf Form’

Intriguing CLUMPING bamboo that rises to only 6′ tall but arches as wide. Fine, arrow shaped leaves protrude in the same direction giving an airy symmetry. Takes pruning very well and is recommended for small spots. In the open give it room to arch. The 1/3″ wide culms clusteer tightly forming a moderately fast increasing clump. After 10 years the base of culms will be no more than 2′ wide. Full sun to part shade to shade in rich soil with consistent summer irrigation. Established plants can take far less. Wonderful in a woodland or as an asian accent in themed gardens. This is a very hardy bamboo- tolerating temperatures slightly below 0ºF. A great bamboo for those in the line of east winds. Plant on 3′ centers for a dense hedge. Prune in spring if needed or allow it to gently repose with natural grace. Moderate deer resistance. SW China.

Fargesia robusta

Fargesia robusta

Excellent CLUMPING bamboo that is adaptable to a wide range of situations. Ultimately 15′ tall the 3/4″ culms rise up green with dramatic white culm sheaths before changing to a golden yellow. The foliage is dense and clusters around the top 3/4th of the canes. Easy to grow bamboo for redistricted sites in high overhead shade to full sun (but avoid the reflected heat of walls). Spreads moderately fast by a steadily increasing clump- each new culm is just inches from the other. Forming a grove to 4′ wide at the base in 6 years. Very upright growth makes it ideal for the thin space between houses, or for shading a courtyard. Regular summer water in rich, moisture retentive soil that drains. Drought adapted when established. Good performance in ice and snow. Hardy.

Fatsia japonica 'Murakamo Nishiki'

Fatsia japonica ‘Murakamo Nishiki’

Fatsias are invaluable in our climate for their tropical good looks, and overall hardiness. They endure dry shade with aplomb and in autumn they explode into exotic bloom with large stems supporting orbicular white flowers. This cultivar has leaves with an interior zone of yellow. Slower growing than the species it will eventually top out at 6′ x 6′ in full to part shade in rich well drained soil. Light summer water. Moderate deer resistance. Cold hardy and very easy to grow. Light consistent summer water speeds growth.

Fragaria vesca var. bracteata

Fragaria vesca var. bracteata

Woodland strawberry that is native to large parts of Oregon. This upright growing smaller strawberry is delightful when pristine white flowers morph into sweet pendant red fruits. To 10″ tall and as wide this clumping plant expands at a moderate clip forming patches in rich to average soil with light, consistent summer moisture. Blooms in April- fruit arrives in June. This is the locally native form of this widespread plant. it differs from the European version in that it produces runners.  I In France the same species is famous as Fraise du Bois. Our local species in Oregon will produce several rounds of fruit with reliable irrigation. It will increase by RUNNERS, the european variety does not run, but clumps. This is not a long lived species and it seems to find its happy place on its own. Expect several years lifespan and leave fruit on the plant annually to ensure reseeding and nurture new plants at the end of stolons. This is our local selection and it is very drought adapted. The European variety much less.  Great in containers. Use in partly shady borders, its a diminutive plant and fits nicely among larger perennials. Great for fresh eating…and dogs like them too so protect from marauding pooches. Very natural lining woodland paths. Semi-deciduous to winter deciduous. Native to the Portland city limits. Oregon native plant

Fuchsia ‘Whiteknight’s Pearl’

Big, huge hardy Fuchsia with much larger and more conspicuous flowers than the similar F. m. ‘Molinae’. To 4′ x 4′ in a season. Continuously blooms from June to frost in rich soil with REGULAR irrigation. This is a thirsty Fuchsia and pairs wonderfully with other thirsty plants as Hydrangeas and Weigela. Large flowers have a sepal and corolla of the same chalk pink. The wood is hardy to about 24ºF and it will freeze to the ground below that. Vigorous regrowth in spring shoots up from the semi-woody framework. Very hardy and recommended for the coldest gardens. Excellent performance on the Oregon coast. Purportedly has some resistance to rabbits but I would not bank on that. Makes a great hedge in full sun to part shade. Excellent on an eastern exposure with afternoon shade. Amend the soil well to enrich for the most vigorous establishment. Excellent in concert with all white flowered Fuchsia ‘Hawkshead’. Hardy in containers. A large plant in full bloom is spectacular.

Genista aetnensis

Mt. Etna Broom is a remarkable TREE from the slopes of Italy’s tallest active volcano. Unlike Scot’s Broom (Cytisus scoparius) this fine, leafless tree will NEVER become a pest in our climate. Rush like pendulous green stems are replete with yellow jasmine scented pea flowers for months in summer. This tree casts no shade but provides an elegant vertical element. The sweet perfume travels many feet on a warm day. Blooms May-August. Fast growing drought adapted tree to 18′ tall and 8′ wide in 10 years. Full, all day sun in a hot position in poor to average very well drained soil. Little summer water once established. Forms a very nice trunk in time. Plant with drought adapted shrubs/perennials. Wonderful small garden tree where you need height but don’t want shade. High deer resistance. Slightly tender when very young- fully hardy as an adult (3-4 years). Spectacular in bloom. No shade, it casts no shade.

Geranium oreganum

Not many gardeners are aware that we have our own native hardy Geranium. And its a really good garden plant. Bushy herbaceous perennial that displays very large magenta-pink flowers in late spring to mid summer. It peaks in June and is quite a display. To 2′ x 2′ and completely deciduous in winter. Excellent in manicured borders or areas that receive a bit of extra irrigation in summer. Adapted to clay soils it improves considerably under cultivation. Mix with native Sidalceas for a bonafide native combination. Native throughout western Oregon but also native in the Rocky Mountains. One of our finest natives that should be used more often. Fall color is yellow before going cleanly away. Not bothered by slugs or snails (!) but not entirely deer resistant. Full sun to light shade to very high overhead shade (a tall tree canopy). Best in enriched soil with consistent summer moisture. Associated plants in the wild are Sidalceas, Achillea. Very good performance in rain gardens. Oregon native plant.

Geranium x ‘Rozanne’

Possibly the best hardy Geranium ever selected. Sky blue flowers with a slightly white center appear non-stop from June to frost on this vigorous and flowery perennial. To 18″ tall and twice as wide or more. Well drained soil of average to rich fertility with light consistent summer water. Planted adjacent to shrubs and trees this perennial may actually act as a climber- rambling up into lower branches and displaying its cheery blue flowers up high. Full sun to light shade and regular summer water. Winter deciduous. As with all hardy Geraniums it shows great resistance to slugs/snails. Unauthorized propagation prohibited. PP#12,175.
