Floral fasciation is a rare developmental disfigurement of a bloom, supposedly caused by the fusion of two or more blooms. Many fasciated blooms really do look like two blooms stuck together, like double daisies. Alternatively, fasciation can cause distention of a single flower of many on a foral spike of foxglove.
Fasciation of lily-of-the-Nile bloom is typically expressed merely as a few stray florets on the otherwise bare stalk below the main floral truss. A smaller subordinate stalk may seem to be fused to the main stalk below the stray florets.
The specimen in the picture above is exceptional. It really does look like a double bloom, with one stacked on top of the other. The atypically short and stout stem looks like a tightly fused bundle of several smaller stems. Those who do not know better might find the more billowy and more colorful fasciated bloom to be more appealing than the normal bloom pictured below.
The first picture of my ‘Six on Saturday‘ post this morning shows that this is not the only fasciated bloom here. There is another similar fasciated bloom right next to it. This suggests that the fasciation is likely caused by a genetic mutation that was shared with each of two rhizomes that split from the original.
If the mutation is sufficiently stable, and not likely to soon revert, more copies could be propagated later by division. The rhizomes split after bloom; so if one split into two last year, the two that are here now could split into four next year. If genetically stable, all four should bloom with the same fasciation next year.
To monitor their genetic stability, I should probably relocate these two odd rhizomes, to separate them from the others for observation. I suspect that they will eventually revert anyway.
It may not look too nasty, but barberry, Berberis thunbergii, is the sort of small hedge that one goes through only once. It does not have big strong branches to hold anyone back. In fact, the limber branches are quite twiggy. The tiny spines are not impressive either, and might go unnoticed by cursory observation. Yet, they are sharp enough and plentiful enough to make quite an impression!
Autumn foliar color is not the concern yet. It develops later as deciduous plants defoliate for winter. Purplish, reddish, yellowish, bluish or gray foliar color that can be seen now is provided by plants that are colorful while actively growing. Almost all of this sort of foliage is most colorful when it is young and fresh, early in spring. Then, through summer, some of the best foliar color fades.
Among pines, firs, redwoods and most excurrent trees (with central leader trunks), stubs or stumps of limbs that were shed are common and more apparent than they are among decurrent trees (which branch into many main limbs). The older lower stubs slowly but eventually decay and fall away as the trunks compartmentalize (heal over) where they were formerly attached.
From formerly dormant bulbs just below where their foliage shriveled in the warmth of last spring, the naked brown floral stalks of naked lady, Amaryllis belladonna, grow fast to about two feet tall. They bloom suddenly with a few or several garish pink lily flowers about three inches long. They are sneaky about it too. Without foliage, and prior to flashy bloom, the bare stalks are easy to miss.
California buckeye, Aesculus californica, is an enigma. How does it survive while defoliated for so much of the year? Not all are so mysterious. Those that live in sheltered or forested situations behave like normal deciduous trees, by defoliating in autumn, and refoliating in spring, after a brief winter dormancy. Those that are more exposed in warm and windy situations make us wonder.
Weeping flowering cherry is another type of tree that almost never gets appreciated like it should. Like so many Japanese maples, they get planted into situation where so-called ‘gardeners’ shear them into nondescript globs of worthless foliage that only get in the way. Some get shorn so regularly that they are deprived of bloom. Their form and bloom are their two main assets.
