An interesting form of Arrow Bamboo, Green Onion develops alternating swollen internodes on older canes that is similar in appearance to the famous but tropical Buddha's Belly Bamboo, with Green Onion Bamboo being winter hardy to zone 6. The thin stems on young plants don't have the onion bulbing, this typically begins to appear on stems that are pencil diameter and is the most pronounced on stems that are about thumb diameter. Mature plants look their best when they are thinned every few years to select for the largest stems and maintain an open habit where the canes are very visible.

Our main crop of most plants is available starting in late fall.

Production notes: in production most years but is unavailable in some due to limited seed/division material or finicky propagation Like the standard form of Arrow Bamboo, Green Onion is an excellent species for privacy screens due to its dense deep green foliage and attractive large leaves. The stems are strong and hold up well to wind, Arrow is also salt resistant and can be planted along the coast. Arrow Bamboo is very shade tolerant and will maintain a dense form even in deep shade, afternoon shade is best when grown in hot climates. The plants spread by the roots so they do best when grown in containers above ground but they can be controlled in-ground with bamboo barrier as well.

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. |
