A reader pointed out that last week in the discussion of fall-blooming wild flowers I failed to mention Maximilian Sunflowers. There is a valid reason for that. I was unaware of their existence. In order to rectify that deficiency I did some research.
The first thing that I learned is that at 75 miles an hour many of what I took to be Saw-leafed Daisies may well have been Maximilian Sunflowers. These sunflowers were named for a German prince that led an expedition into the American West in the 1830’s.
These perennials are native from Texas northward into Canada. They grow upright from two to 10 feet in height. Bright yellow flowers which are as large as five inches in diameter are borne on the upper portions of the stems.
These flowers grow on the terminal ends of their own stalks or from the leaf axils (area at the base of the leaf between the leaf stem and the main stalk). The sunflower’s leaves are lance shaped being more narrow at both ends than in the middle.
The Maximilian sunflower does not seem to be very picky about the soil type in which it grows but a full sun exposure is necessary. Inadequate sun, over watering, and too much fertilizer tend to produce weak stalks that fall or blow over easily. Some growers recommend that the stalks be tied up to a fence or other support when these plants are put into the landscape.
These sunflowers can be grown directly from seeds which are available commercially from both the large mail-order houses and the major wild seed suppliers. It appears that the usual poor germination rate can be improved by placing the seeds in refrigeration over the winter. The plants are reported to bloom the first year.
These perennial sunflowers grow not only from seeds but also from underground rhizomes. Another, and perhaps more reliable method of propagation, is to divide the rhizome clump in early spring then replant and water immediately. Like many plants that reproduce from rhizomes as well as seeds the Maximilian sunflower can become invasive.
Maximilian sunflowers are grazed by livestock and the seeds produced are food for several bird species. Bees also make use of the nectar and butterflies, including Monarchs, like the nectar and a place to rest. The rhizomes were eaten raw and cooked by several Native American groups. The young shoots can be eaten raw or cooked in stir fry or soups.
Another reader asked me what I knew about Burkett pecans. My answer was that, in addition to generalized pecan information, I knew that they made good pies. That seemed to be an inadequate answer so I resorted to more research.
Burkett pecans were discovered in Callahan County in the fall of 1900 by the sons of J.H. Burkett. It was introduced into the market in 1911. The trees are recommended by the Texas Pecan Board only for landscape trees in West Texas. It is not recommended that they be planted in the rest of Texas because of the diseases of scab and downy spot.
The female organs of the Burkett mature before the male organs with pollen shed being in the mid-season. Pecans do not come true from seed since the nut is the product of the pollination of one tree by another tree.
Like humans, the resulting offspring will be a blend of the genetics of the parents. Burketts are used by growers as the female parent of “Apache” and “Comanche” varieties. Burketts are prone to pre-harvest germination resulting in unusable nuts.
In case you are interested, according to the Texas Forest Service the original budded tree was located in Callahan County. It was on the north edge of Interstate 20 about a half mile east of Farm Road 880. The original tree was destroyed in 1910.
The beauty of writing this column is that I am always learning.
