<br />,oOn4c,s <br /> <br />they might deem important, and to fill in with objects <br />from nature. It is not our intention to try to bring <br />back or create a ceremonial event, but rather to <br />recognize what a unique experience it is to be an <br />intern at The Land Institute. The circle is a gift to <br />The Land and to all interns past and future. We <br />would like to think that each intern who has been or <br /> <br /> <br />The Sunflower <br />Puzzle <br /> <br />Tracy Noel <br /> <br />Anyone who <br />walked near the green, <br />house or classroom <br />building this last <br />summer likely would <br />have noticed a sun, <br />flower that wasn't <br />familiar. <br />The plants were nearly twice as tall as a <br />person, but the surprisingly narrow semi-woody <br />stems, that seemed to be just stuck into the ground, <br />managed to remain vertical in even an average <br />Kansas wind. An aspiring botanist might have <br />guessed by the long slender leaves and light colored" <br />flower disks that this was Maximilian sunflower <br />(Helianthus maximiliani) with an extra dose of tall <br />genes. Knowledge that The Land Institute has <br />studied Maximilian sunflower might have helped in <br />making this assumption. Closer examination would <br />have revealed a few flowers with darker disks and <br />leaves that were smooth and not hairy like those of <br />Maximilian sunflower. One might then conclude that <br />more than one species had been planted; and the <br />other species, given the long smooth leaves and the <br />dark flower centers, was probably willow leaf sun, <br />flower (H. salicifolius) which, like Maximilian sun, <br />flower, is a native perennial. <br />Though this wouldn't be exactly correct, I <br />would applaud the botanist for getting much farther <br />than I did without a handy wildflower guide. ' The <br />truth is that the seeds from which these plants grew <br />were collected from only one species. In 1989 staff <br />ecologist Jon Piper collected H. salicifolius seeds from <br />the herbary, which was established in 1978 to evalu, <br />ate about 300 different perennial species for research <br />as potential crops. Jon planted these seeds in the <br />greenhouse, and they were transplanted into the <br />flower bed west of the greenhouse and also in the <br />garden east of the classroom. So why was there <br />variation in the flowers? <br />Maximilian sunflower is a native species which <br /> <br />'1' <br /> <br />will be a part of these surroundings will flnd some <br />personal significance in the season circle. For all, it <br />can be a celebration of the cycles of interesting and <br />eager people who come to The Land as interns each <br />year. Just like the cycles of the seasons, each is <br />constant, yet unpredictable, and no less significant <br />than the last. <br /> <br />readily hybridizes with other members of the sun, <br />flower family, and it too had been evaluated in the <br />herbary. Since flowering times of the two species <br />overlap-H. maximiliani flowers from late July to <br />mid-October and H. salicifolius flowers in September <br />and October-pollen from Maximilian no doubt <br />reached ovules of the wiJIowleaf plants from which <br />Jon collected his seeds. Plants which grew from these <br />seeds took on many traits of Maximilian sunflower, <br />and plants which grew from seeds pollinated by other <br />wiJIowleafflowers naturally took on willowleaftraits. <br />Now we can conclude that several of Maximilian's <br />traits are dominant when crossed with willow leaf. <br />As for the height, both Maximilian and wil- <br />low leaf are among the tallest of perennial sunflowers, <br />Maximilian commonly reaching about ten feet and <br />wiJIowleaf eight to nine feet. Our eleven feet tall <br />plants could be a result of vigor common in second <br />and third year perennials. They could also be evi- <br />dence of the idea that "two bigs make a bigger." Or <br />maybe they're simply the products of a little love. <br /> <br />, <br /> <br />~~ <br /> <br />~ <br /><-; <br />~ <br />, <br />7 <br />!i <br />t; <br />~ <br />k <br /> <br /> <br />" <br />~ <br />t <br />~ <br />~~ <br />~ <br />.;: <br />~ <br />i <br />,~ <br />':~ <br /> <br />,.. <br />}~;, <br />S <br />:} <br />~:) <br /> <br />i~ <br />'i." <br /> <br />~: <br />io.; <br /> <br />,.' <br />.,i; <br /> <br />..:; <br /> <br />Tracy, on Jake's shoulders, checks sunflower Might. <br /> <br />~:.: <br /> <br />:'-}, <br /> <br />32 <br /> <br />, <br />'..; <br />~~.. <br /> <br /><}. <br />~<~. <br />
