Plectranthus (Isodon) longituba

I can’t imagine my garden in autumn now without this crazy late blooming blue, blue blue perennial. To 6 ‘x 6’ long stems terminate in clouds of bright blue guppy shaped flowers beginning in mid-October and continuing usually until the first hard freeze- often mid-December in the city. Part shade in deep rich moisture retentive soil. Kind of a quiet plant until autumn and then holy shit. Clouds of blue guppies people. Clouds of blue guppies. Often it gets yellow fall color simultaneously with this display. Incredible cut flower at a weird time of the year. Regular water all through summer. This plant gets big, big, big. Perfectly hardy to cold way below zero. So happy I found you Rabdosia now Isodon which sounds more like a freaking Dinosaur than a groovy late fall blooming perennial. Give this plant room, it will get much larger than it looks in a nursery pot. It can be nearly tucked behind shrubs or taller late season perennials. It often turns a soft straw color in concert with the blue flowers. Foliage out of flower is somewhat dull but the fall display makes it worth it. Native to Hokkaido, Japan. Formerly known as both isodon and before that Rhabdosia. Seems to have settled into the mostly tender genus Plectranthus. Fabulous late season perennial.

Podophyllum pleianthum

Bold species of Asian Mayapple with huge glossy leaves 2′ across with finely serrated angular sides. To 4′ tall and multiplying first by an expanding the immediate clump then in subsequent years it roams via stolons. In time creating prodigious colonies. In May/June pendant deep red odiferous flowers radiate from below the leaves and may be followed by ripening “apples” into autumn. Rich, well drained soil with regular summer irrigation. Part shade to full shade. Requires ample protection from bright sun. Winter deciduous.

We’ve met a lot of good gardeners and I’m always most amazed at peoples attention to detail. Good gardeners love detail. Mary De Noyer is a favorite customer and well known for her fastidious and beautiful garden. Several years ago Mary brought this seedling Podophyllum to us and asked that we grow it. Her only stipulation was that we name it ‘Audrey’.  Done! This is a remarkable perennial that we are proud to finally have a salable population. The large convex star fish shaped leaves are a glowing amber to madder red. Following the unufurlment and maturation of the leaves pendant dark wine red flowers appear on the leaf petiole- in this case the trunk. To 2′ tall a mature leaf can be more than 1 foot across. This probable hybrid May Apple is a bold and beautiful perennial for part shade to high overhead shade in rich soil with consistent summer moisture. Add all purpose fertilizer around the base each spring. For the first several years the clump of bold leaves increases close to a clump. After permanent establishment and with a lot of moisture this perennial will run by stolons. It will run as far as rich, moisture retentive soil allows. Beautiful plant. Thank you Mary De Noyer.

Polemonium carneum

Our native pink Jacob’s Ladder is a great plant for gardens. Hailing from valleys adjacent to the Cascades as well as the coastal strip the finely divided foliage of this clumping perennial is attractive but enhanced when the clusters of very pretty flowers open the palest pink aging to lavender over several days. Full sun to part shade in rich moisture retentive soil. To 28″ tall and somewhat spreading. Blooms for an extended period from April to June. Summer drought will bring dormancy but a little bit of water keeps it green. Great tolerance to dry clay soils and it persists in conditions that would end lesser perennials. Mixes well at the margins of woodlands or the front of perennial borders. Even in its habitat it tends to flop, or rather lean on its neighbors. Expect this and use it to an advantage. The softly colored flowers will wind into other plants playfully and you can achieve really cool and wild appearing vignettes. Very good in concert with native Geranium oreganum as they bloom simultaneously.  A really pretty native perennial. Adaptable to heavy clay soils. Soars in rich, amended soils and can be quite a bit larger than I’ve listed.  Fairly good cut flower.  Oregon native plant.

Polypodium guttatum

Fun little hardy evergreen polypody that has perfectly vertical fronds that rise to just 6″ high. In time it forms dense colonies. Very fun to grow in part shade to shade. A great evergreen texture to repeat in a woodland. Excellent appearance even after the most brutal winter. Surprise. To 2′ wide in rich, hummusy soil and regular summer water. Apply an annual application of mulch right over the top of the leaves each spring to feed and hold moisture . High deer resistance. Doesn’t normally begin growing until consistent days above 70ºF. Cold hardy to 5ºF. Evergreen.Easy to grow. The mountains of Mexico.

Polypodium scouleri

Coast Polypody or creeping leather fern is an evergreen colony forming plant that is native from British Columbia south along the coast to even the Guadelupe Island off of Baja. It makes its home as an epiphyte trees, logs, rocks, the ground almost anywhere it finds adequate moisture and shade. During the summer it will take a surprising amount of dryness but we recommend light consistent irrigation for the best appearance and to spur multiplication. Fronds to 10″ long with rounded lobes. Excellent garden plant, grows very well in rich to average soil as well. Good year round appearance. A native fern that should be grown all the time. Great in winter containers- excellent winter appearance with little maintenance. Protect from hot sun. Highly deer resistant.  A natural for the Oregon coast  which is its native home.  Oregon native plant.

Polystichum minutum

Western sword fern is one of the most ubiquitous plants on the west side of the Cascades. In many forests in the Coast Range and Cascade foothills it is the sole understory plant. Western sword  fern is a large species with long arching fronds. Adaptable to a host of situations. Often self sown spore will show up in the oddest places. I’ve seen it as an epiphyte and even self sown into hot concrete steps. In rich, acidic soil this evergreen fern soar- provided soils rich in humus, organic matter and protected from direct sun with consistent access to water. Very well adapted to our winter wet/ summer dry climate- it will cruise through dry summers unscathed. In the garden it does useful duty in the toughest, dry, shadiest sites. Along with Cast Iron Plant (Aspidistra elatior) and Ophiopogon (Lily turf) it is one of the best dry shade inhabitants. As an understory component it is often accompanied by Cascades Mahonia (Mahonia nervosa), Inside-out-flower, (Vancouveria hexandra), and Pacific Blackberry (Rubus ursinus). To 4′ x 4′ in ideal situations. Though it is evergreen western sword fern does go through a transitional period before new croziers unfurl in spring. The 3′ long fronds begin to lie flat on the ground by winter. This is the time to remove tired, old leaves. and make way for fresh, new, unfurling foliage. Though very tough western sword fern does look its best with consistent light water.  Supremely deer and rabbit resistant. Long lived and not a slow grower.  Oregon native plant.

Polystichum setiferum var. divisilobum

Soft Shield fern is native to Alaska- well points north in general. That means its bone hardy to cold but its also a fantastic evergreen fern for dry shade in our region. Finely divided fronds taper to 2′ long. The central stem is a soft furry brown- good contrast. Spreading colony creating fern to 3′ across. It has the unique habit of vivipary. It makes small new plants spontaneously right off the frond. Useful. Good looking appearance year round. Rich, moisture retentive soil with regular water to establish. Incredibly drought adapted when older – as long as its in shade. High deer resistance. May be cut back hard in early spring to refreshen. Grows very quickly.

Primula ‘Guinevere’

Good reliable perennial Primrose with dark maroon leaves and stems in great contrast to the simple lavender pink flowers. A nice yellow eye adorns the center of each flowers. Blooms February to early May. Low growing form that makes colonies over time in rich, moisture retentive soil with regular water. Must have regular summer water to survive the drought season and this one will without huge amounts of effort. Under shrubs in woodland glens. Easy perennial.

Primula sieboldii ‘Ice Princess’

My personal favorite primrose. This sieboldii selection blooms later than others but the flowers which are soft blue on the back of the flower and have a pure clean white face on the front. Heavily frilled petals are elegant on 8″ stems. Blooms May to early June in cooler years. No other cv of P. sieboldii comes as close to true blue. Forms a clump in time in rich, moisture retentive soil in part shade. Goes quickly summer dormant with true heat. Still water the roots of the dormant plant- they like that and will reward you with a greater show the following spring. Mix with Lamium maculatum ‘Aureum’ and Tiarella ‘Steam Punk’ for the same cultural conditions and a long spring to summer show. Great around the base of hardy Fuchsias as well. The leaves of the Primula disappear just as the Fuchsia is gaining steam. Excellent selection of this long lived spectacular Primula.
