Plant Spacing: 5ft apart Flowers: hundreds of yellow sunflowers produced from June through September Leaves: herbaceous, plant dies back in the fall and re-sprouts from the roots next spring One of the most drought tolerant flowering species we grow, the Maximilian Sunflower thrives in dry soils with only occasional watering. The plants have an open habit and often seem to have more flowers than leaves through most of the summer, with new flowers opening daily even without deadheading. Unlike many common sunflower varieties, Maximilian produces a large number of side branches which is what allows the plants to produce flowers over such a long time period. Maximillian was also one of our favorite plants for cut flower production in our early years due to its long stems and the lack of dense foliage around the flowers. For shorter bouquets, like 12-14 inches tall, there typically aren't any leaves to strip from the flower stem which was a big time saver compared to annual varieties that produced masses of foliage right up to the flower bud. The fact that this is also a perennial species that comes back every year without having to replant is also a bonus.
In our mild zone 7b climate we are able to produce winter crops such as kale that are seeded directly into our Maximilian patch after cutting the stems down in October. Our kale, spring onions, or radishes are ready to harvest by the time the sunflower shoots start poking up out of the ground in late April or early May.
This sunflower species is native to various midwestern plains in North America and its seeds are an important winter food source for many native bird species.

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. |
