Even after so many pretty shades of yellow, red, pink and and white have been been developed, the natural orange of the native California poppy, Eschscholzia californica, is still the best. That is probably why they all eventually revert to orange after reseeding. Although native, they do not reseed everywhere, and actually seem to be more reliable in unrefined and unamended areas of the garden than in rich soil with generous irrigation. However, a bit of watering can prolong sporadic bloom until autumn. Bloom otherwise ends before warm summer weather.
California poppy is grown as an annual because the perennial plants get tired rather quickly. They fortunately self sow prolifically. Flowers are typically about two inches wide, with four petals. The intricately lobed leaves are slightly bluish. Foliage is not much more than half a foot deep.
Colorado must really like blue. Not only is the state tree the Colorado blue spruce, but the state flower is the Colorado blue columbine, Aquilegia caerulea. However, the flowers are not always blue, and in fact, are often white or various shades of pink or soft yellow, or a combination of two colors. The many other specie and hybrids of columbine add even more shades and combinations of richer shades of blue, red, yellow, orange and purple. The distinctively lacy foliage is somewhat bluish. A few varieties have chartreuse foliage.
Although potentially perennial, most columbine do not reliable regenerate after winter dormancy, so are instead grown as spring and summer annuals. Flowers are not as abundant as those of other annuals, but are interesting close up, and very attractive to hummingbirds. Mature plants stand about a foot tall, so work nicely in pots surrounded by lower and more colorful annuals like lobelia and alyssum. Columbine prefers partial shade and rich soil. Plants in full sun tend to be more compact and seem to be a bit faded. Incidentally, some parts of the plants are toxic.
Alaska, the biggest state in America, claims one of the most diminutive state flowers; their native alpine forget-me-not, Myosotis alpestris. Common woodland forget-me-not, Myosotis sylvatica, is the more familiar species here. It is not as common as the name implies though. Where naturalized, it stays within riparian or coastal situations, where the soil does not stay too dry for too long.
Forget-me-not is not notably popular in home gardens nowadays either. Of course, that only means that it is not often planted intentionally. Like violets and alyssum, it can proliferate where it gets a bit of water. Those who recognize it as more than a weed often leave it to provide delightful sky blue bloom until it succumbs to the warmth of summer. It is pleased to toss seed for the next year.
Common woodland forget-me-not is an annual, or at most, a biennial. Self sown seed starts to germinate through autumn, and grows into plants that can bloom before the end of winter. Manually sown seed wants to be in the garden early too, even if it grows slowly. New plants are too delicate to be commonly available in nurseries. Mature plants are less than a foot tall and two feet broad.
Colorado is another state that was able to designate one of the most excellent wildflowers of North America as the Official State Flower because it happens to be native there. Rocky Mountain columbine, Aquilegia caerulea, however, did not contribute as much to the breeding of the many modern hybrid varieties of columbine as did common European columbine, Aquilegia vulgaris.
Most are short term perennials that are more often grown as biennials or, if they do not continue to perform through the dry warmth of summer, as spring annuals. Seed can be sown directly earlier in spring, but new plants may not bloom until the following spring. Plants that are grown in a greenhouse through winter, as well as self sown plants that grow though winter, should bloom in spring.
The famously spurred flowers can be just about any color; white, blue, purple, red, orange, yellow, pink and even pale green (fading to white). Most are combinations of two colors. Some varieties proudly bloom with frilly double flowers. The thin flower stems stand about a foot tall, with flowers facing slightly downward. The trifoliate and delightfully lobed leaves are like big lacy clover leaves.
If California is the most excellent state in the entire Unites States of America and surrounding Universe, and Oklahoma is the second most excellent, then Oregon might be number . . . hmmm . . . fourteen or fifteen . . . or maybe like twenty or something. However, in MY (very important) opinion, Oregon is like the third most excellent state, and almost ties with Oklahoma! That makes it even slightly more excellent than Pennsylvania, Vermont and Arizona! Yes, it is THAT excellent!
Even the state tree of Oregon is excellent. It is the Douglas fir, pseudotsuga menziesii. That is like the second most excellent of the state trees, right after the coastal redwood of California. If California did not claim the coastal redwood as the state tree, Oregon is the only other state that can claim it as a native, since the native range of coastal redwood extends ever so slightly into the very southwest corner of Oregon.
There was a time when redwood was the main timber tree here, but that was only because it was the most readily available. As the supply was depleted, it was reserved for fences, decks, structural lumber that is in contact with concrete foundations, or any other situation in which its innate resistance to decay was important. Douglas fir became the most common lumber, and is still what homes are built from now.
Besides all that, Douglas fir is one of the grandest of trees in North America.
Then there is the state flower of Oregon. Well, it is not so much to brag about, although it is still better than the state flower of Oklahoma, which happens to be mistletoe. (Okay, that is another subject for later.)
Oregon grape, Mahonia aquifolium, blooms late in winter with these bright golden yellow, but otherwise unimpressive flowers. The few small black berries that develop over summer are mostly taken by birds before anyone notices. The glossy and prickly dark green foliage is quite appealing, and happens to do well in partial shade, but this is the state flower, not the state foliage.
Oregon has good taste. Douglas fir, one of the most useful of timber trees in America, was selected as the state tree. Oregon grape, Mahonia aquifolium, was designated as the state flower. Although the tight clusters of tiny bright yellow flowers that bloom about now may not be as flashy as other state flowers, they contrast handsomely against the glossy and deep dark green foliage.
The pinnately compound evergreen leaves are larger than they seem to be. The smaller individual leaflets that resemble holly get noticed first. They are are not quite as wavy, spiny or thick as leaves of English holly are, so can work well where spiny foliage would be objectionable. Dark grayish blue berries are not abundant, but happen to make good jelly for those who hunt for them.
Mature plants get about five feet tall and broad, and can spread wider like Heavenly bamboo does. Foliage might be a richer shade of deep green, with a slightly more relaxed texture, in partial shade. A few garden varieties are available, including some that are more compact, and some with more rounded leaflets. Old canes should be pruned out as they get replaced by newer canes.
