Campanula


          Campanulaceæ is the "Bell Flower" family and includes all of the genus Campanula and some others. Alaska's members of this group are all in the genus Campanula and called "Hare Bells". That insinuates they are not true Bluebells , which of course, they are.
          The flowers of this group are identified by their corollas being fused with five lobes, and they have five sepals. There are five stamens with noticeable anthers at their filament tips.
          The pistil has a superior ovary (above the sepals) and a three parted stigma at the top of the style. Notice that the stigma in the photo insert (left) clearly shows only two, the third is behind the one on the left and is barely visible.
          The species with the largest flower, found in Alaska, is Campanula lasiocarpa, a very small plant with beautiful large flowers. It is found in alpine heaths and gravel in the mountains. It is abundant along the Denali Highway at mile 17 and in a gravel pit area at mile 70. It also can be found in other areas: Crow Pass, Hatcher Pass, and it is common at Paradise Lake on the Kenai peninsula. You may find it whenever you are high in the mountains or far north. Its range is restricted to the lands of the North Pacific, to the Arctic and into North Western Canada.

          Liliaceæ (Lily) is a typical Monocotyledon having petals in "threes" or multiples of three. They lack sepals and have stamens in "threes' or multiples of three. A single style with a flattened stigma at the top is usual for this genus.
          Leaves of Monocots have all veins beginning at the center vein at the bottom and meeting at the center vein at the tip, No cross veins occur in monocots.
          As with most lilies, this species has no true "bulb". A bulb is an underground leaf bud being nothing but young leaves. An onion is a true bulb. Most lilies have corms.

Things To Remember
  • A pistil has an ovary, a style and a stigma. A stamen has a filament with an anther at its top.
  • Sepals are a division of the of the calyx before. The Calyx is all of the sepals together.
  • Anthers are the pollen bearing part of a flower. Petals may not be present on some flowers.
  • Bracts are reduced leaf or leaves before the pedicel which is the flower stem.

clematis petiol

          Yellow Clematis (pronounced klem-ate'-us, see Webster's Dictionary) is one of those rare vines that do especially well in Alaska. They will grow as high as a two story house and the most severe winter never seems to bother them.
          In the spring they look and feel dead and dry, but they soon sprout leaves and climb fencing or poles using their leaf petioles to wrap around anything they touch (left clasping its own stem).
          The flower (above) has no petals, it has yellow sepals, dark brown stamens and greenish anthers.
          At left is the flower with sepals removed showing how the styles grow and spread after pollination by, primarily, bumble bees.
          The seed head then turns upright and the filaments grow and spread. At first they produce a beautiful silver bouquet and then becomes much larger and remains like a mass of white puff-balls through the winter.

          In the far north, the seeds (right and far right) do not blow and grow as weeds in your yard. They must be taken indoors before a hard freeze (early October) and planted in trays or pots in early April indoors. Plant them out June 1st with lots of climbing space, with their roots in the shade and the vines in sunlight. They don't need scarifying in cold to germinate. Just keep them in a dry place in the house until ready to plant.
          In my Alaskan home, I built a tall garden gate for them to cover, arbor-like. If you make one, it must be strong enough to withstand heavy snow, because this plant becomes very dense.
