Scouler's Willow is native to a wide range of climates across the west coast from Alaska to California and is one of the few willow species that grows on dry, free draining mountain slopes in addition to wetland sites. Willows are critically important for many native species, with the dense branch structure supporting crucial shelter and nesting sites for many bird species and the very early spring flowers providing nectar for native pollinators at a time when little else is available. The twigs are also an important browsing source in late winter when other food has become scarce. Scouler's Willow allows for these functions to be provided on drier sites where other willow species would not survive.

unrooted cutting - $1.25 each deep plug - $6.50 each Scouler x Sitka hybrid - deep plug - $6.50 each
Our main crop of most plants is available starting in late fall.
Additional batches of plugs and quarts are added throughout the year.
Many of our plants are propagated in limited quantities and can sell out quickly when posted, get on the notification list below so you don't miss out. Add your email to be notified as soon as we have them back in stock:

Production notes: in production most years but is unavailable in some due to limited seed/division material or finicky propagation In the landscape, Scouler's Willow has glossy deep green leaves and a wide form, making for an excellent summer windbreak. Plants can quickly achieve 20-30 foot heights as a multi-stemmed tree with a 10-15 foot width. The wood is much stronger than most willow species and because it tends to produce long unbranched first year stems it is an excellent source of garden stakes or tool handles. We prefer Scouler Willow stakes to bamboo stakes in our nursery because they are much stronger. This also makes Scouler Willow plants very conducive to windbreaks.
Like many willow species, Scouler's Willow has significant variation between populations. At the edges of its range Scouler Willow will hybridize with other willow species which can provide plants with intermediate characteristics. Fully upland plants tend to be shorter with browner stems and smaller leaves while lowland plants have some characteristics of Sitka Willow such as a taller, more upright habit and lighter green to yellow stems with longer, slightly serrated edges. The lowland populations are generally easier to propagate and grow in garden settings while plants from the upland populations tend to be a little bit tricky to transplant or grow from cuttings.

Packing Plants For ShippingWe pack our plants depending on the needs of each species and size, most plants ship best with the roots packed in moist sawdust or bark fines but some species don't like root disturbance and are shipped in a soil-less growing media. Excess soil is washed from the roots in preparation for shipping (18-24" White Pines)  Plants are bundled together to fit in boxes  Bundles of plants are secured in long boxes. Plant Sizes 3 gallon Dawn Redwood  Standard quart shrub  Standard 14-18" multi-stem tree size  Standard deep plug pine tree Bamboo Plants Are Shipped In Their ContainersBamboo roots are not flexible and so plants have to be shipped in their containers. These plants are heavier and are shipped separately from bare root plants. Because they are potted they can handle longer transit times so can ship via UPS Ground instead of USPS Air Mail. Potted plants can also be shipped year-round.We regularly top our 1 gallon bamboo plants at 24-30 inches tall throughout the growing season. This results in dense, bushy foliage while allowing for economical shipping. From this size most running species will grow to 5-6 feet tall in the first spring and clumping species will usually grow to 4-5 feet tall.  1 gallon bamboo plants strapped in and ready to be sealed. Unpacking Bare Root PlantsYou will be sent tracking details as soon as your plants are shipped. Unpack your plants as quickly as possible after they are delivered. We use two types of boxes, side-sealing and top-sealing. For boxes that are taped along the whole length you can cut the tape on either side and remove the plant bundles by cutting the tape holding the bundle to the bottom. For boxes that are sealed on the top and bottom, it is easiet to open the bottom of the box (the shipping label is at the top) and pull the bundle of plants out straight out. Check that the box is empty as there can be a second bundle of plants stuck towards the top. A bundle of trees. What if I am not able to plant right away?You can usually leave the plants in their shipping container unopened for 1-2 days if there were no shipping delays and you have received your plants from late November through February. Plants shipped when it is warmer can't stay in their packages for as long.For longer term storage of plants you can pot them up or plant them in rows close together temporarily and then pull them out later in the spring to be planted again. This keeps the roots moist while allowing for air flow to the tops. The roots should have good contact with the soil to ensure they have access to adequate moisture. |
