Thunderhead Dwarf Japanese Black Pine


'Thunderhead' Japanese Black Pine is a wonderful compact specimen conifer.  Like most pines it is drought tolerant and deer resistant but what sets it apart from other pines is it's tight, dense form and handsome white candles in spring that stand out from the dark green needles.  It is a slow to medium grower ranging from 5-10' tall and 5-8' wide but keeps it's dense form over time.  This Japanese Black Pine will tolerate drier, sandy soils or moister soil as long as it's well drained and requires full sun. They look striking in trios or as a specimen in a smaller garden.  Makes a great pairing with the white bark of birches, or yellow Spirea 'Ogon', or purple Smokebush.

'Biokovo' Hardy Geranium (Cranesbill)

BiokovoThis versatile and easy-to-grow hardy geranium is a great choice for an evergreen perennial that is deer resistant, drought tolerant in part shade, and even gets fall color.

When looking for deer resistant plants it's always imortant to seek out scented plants, especially leaves with a strong smell. 'Biokovo' Geranium is one of the rare perennials to have a strong, spicy scent that is not Meditteranean or needing lots of sun. It performs best in a cool location with morning sun or at least protection from the hottest part of the day. The broad, lobed leaves provide striking contrast to finer leafed perennials and grasses.

'Biokovo' spreads by rhizomes to make a nice spreading mound about 6-10" tall and 2-3' wide and can be a bit aggressive so make sure it's neighbors can hold its own. Dainty, pale pink to white flowers with pink stamens emerge in late spring through summer, but this perennial remains interesting all year. The variety 'Cambridge Blue' is similar except with a lavender-blue flower.  We usually have several varieties of hardy Geranium in stock; they're great, tough, long-blooming perennials!

geranium biokovo fall coloCool fall weather brings out vibrant red and gold tones in some of the leaves but the leaves don't go completely dormant so you won't have an empty spot there in the winter. This tough geranium can be drought tolerant once established but will look freshest with regular water and a shearing after winter. A great groundcover for use with bulbs as it will mask fading bulb leaves and add flower interest after the bulb flowers are done. This is our go-to plant for a deer infested shade garden!

Baptisia australis

Blue False Indigo


Baptisia or Blue False Indigo may not be all that familiar but it should be for it's striking purple flower stalks and refreshing blue-green foliage.  It has what we always look for- drought tolerant (has deep roots), deer resistant (poisonous), good cut flowers (blooms in late spring), long lived (so can require some age to bloom and is slower growing), North American prairie native (can tolerate clay or sandy soils), and butterfly attractor.  The easy to care for Baptisia can get 3-4' tall and 18"-3' wide and is rather vase shaped, so low growing perennials at it's base might be nice. Looks great with chartreuse Euphorbias, round headed Alliums, or silver Artemesia nearby. The sweet pea-like flowers make a great contrast with grasses as well. We have an exciting new variety called 'Solar Flare' -  a sulphur yellow that just grabs your attention.

'Summer Ice' and 'Eternal Fragrance' Daphne

Daphne_Summer-Ice-plant-of-By far, one of our most asked about plants!

Daphne Eternal FragranceThis species of Daphne blooms throughout the spring, summer and fall, and is less fussy than some of the other Daphne species. We generally carry two varieties: 'Summer Ice' and 'Eternal Fragrance'.

'Summer Ice' (pictured left) has a creamy, variegated edge. Plants get about 3 to 4' tall by 4 to 6' wide, and has a moderate growth rate. 'Eternal Fragrance' (pictured right) has plain green leaves and is more compact (2 to 3' tall and wide) and slower growing. 

Daphnes are considered partially evergreen plants. In mild winters, they will will keep almost all their leaves, but in severe winters they will drop quite a few leaves - but will flush out beautifully in the spring. What Daphnes are known best for is their fragrance. A light wind will carry their musky sweet fragrance to wherever you are in the yard. 

Daphnes will tolerate full sun, but in our climate a little protection from hot afternoon sun is probably best. We have a huge 'Summer Ice' on the east side of our office and it seems very happy there. While D. transatlantica isn't as picky about watering as other Daphnes, well-drained soil is best. These plants are also deer resistant, and fairly drought tolerant once established. Like all Daphnes, though, it doesn't like to have its root system disturbed so be gentle when planting and don't try to transplant it once it's settled.  


We also regularly carry two other types of Daphne that are a bit fussier, water-wise - but are well worth the effort:

Daphne odora (Winter Daphne): Winter Daphne gets to approximately 3 to 4' tall and wide, and there are both plain and variegated-leafed varieties. One of the secrets of successfully growing Winter Daphnes is to make sure they have excellent drainage. In heavier soils, plant them slightly higher than the surrounding soil, or plant on a mound.

Daphne Lawrence CrockerDaphne 'Lawrence Crocker': This is a really sweet dwarf Daphne (just 12" tall and wide) with purple flowers. Daphne 'Lawrence Crocker' was named after one of the original partners of the Siskiyou Rare Plant Nursery, and this plant is a lovely namesake. They also prefer well-drained soil, and are an excellent addition to a dry shade garden. 

Pulsatilla vulgaris

Pasque Flower


Of all the flushes of new growth and bright flowers of spring, Pulsatillas are my favorite harbinger of this vibrant season.  Among the earlier of perennials to bloom, Pasque flowers emerge from dormancy covered with silky hairs that lend a silvery tone to their soft green, lacy leaves.  They quickly produce fat buds that are equally furry; the entire plant just begs to be touched!  These buds open into both nodding and upright cup shaped blossoms in shades of purple, red and white.  Their stamens are arranged in a ball of golden color with a tuft of purple in the center, looking like a little pineapple.  The seed heads that follow are akin to thin, silky feathers gathered into pompoms that last for weeks, swaying in the slightest breeze and really adding to the overall show.  Pulsatillas are one of those refined yet bold flowers that don't need any frills to be visually exciting.  They truly stand out when placed at the edge of a border or nestled among boulders in a rock garden, especially when scattered about.  They can reseed themselves if happy, although not so heavily as to be a nuisance.  The seedlings of this special perennial are welcome in most gardens and often vary in bloom color from their parents, creating a wonderful blend of tones throughout their clumps.  Pasque flowers are best situated in a spot with plenty of spring sun, but some afternoon shade during the hot summer months, otherwise they simply go dormant early.  This can be achieved by placing them next to a perennial that does not have much of a presence in spring, but come summer is a towering, shade providing neighbor.  Native to the prairies and steppes of central Europe, Pulsatillas prefer well drained soil and will even tolerate gritty, nutrient poor soil.  On the smaller side, Pasque flowers only reach 6-8 inches tall and spread 12-18 inches in time.  Their diminutive stature allows them to be easily stashed into any remaining blank nooks that show up in the springtime garden.  Year after year this sweet little plant will reward even the most negligent gardener when it sparkles with morning dew in March and is smothered with jewel toned beauties throughout April.
