One of the mysteries of the English language finally explained.
1A plant of the daisy family that has bright rayed flowers, typically of purple or pink.
- ‘Sow annual flowers such as asters, cosmos, zinnias and marigolds as soon as the frost has passed and the air begins to warm up.’
- ‘Among the favorites are asters and daisies, milkweeds, mustards, mints, peas, and vervains.’
- ‘There are flowers everywhere in a carpet of colour: orange globemallows and white asters and purple lupins.’
- ‘As with other members of the daisy family, annual aster flowers are composed of many long, slender petals radiating from a central disc of bright yellow.’
- ‘As tender perennials are damaged by frost, remove them and pop in fall-blooming asters, chrysanthemums, and pansies.’
- ‘The fastest-growing asters require yearly division in spring.’
- ‘Plant late-blooming asters behind shorter perennials to hide the damage until they finish blooming.’
- ‘Butterflies feasted on purple asters, and dragonflies zigzagged over the buttonbushes, which bore a crop of round, dry fruits.’
- ‘Roses, pansies, perennial asters, zinnias and even weeds become mildewed.’
- ‘The aster is considered the other classic autumn flower.’
- ‘Then, long after the foxgloves have withered and the last crabapple has rolled from the tree and been carted off by a brown squirrel, the asters bloom, the last flower before snow.’
- ‘But asters also come in a full range of reds and pinks, plus white.’
- ‘After the first hard freeze, cut back perennials such as aster, campanula, daylily, phlox, and veronica, leaving 6-inch stubs above the ground.’
- ‘When new leaves appear, divide asters, bellflowers, chrysanthemums, daylilies, sedums, Shasta daisies, and yarrow.’
- ‘Small-flowered plants such as asters, coral bells, nemesia, and yarrow are great fillers.’
- ‘Purple asters bloom in fall, attracting monarch butterflies and providing one last blast of color when many blooms have faded.’
- ‘After a bit of a summer lull, the blues of woodland asters and the yellows of woodland goldenrods render the forest vibrant in late August.’
- ‘These asters make excellent backdrops for larger flowers in bouquets, but we also like letting them shine on their own - toward the fronts of borders or in small, densely planted beds.’
- ‘Not long after we moved from our small, shady city lot to a sprawling sunny piece of land in the country, we were rewarded by a visit from a flock of monarch butterflies that stopped to feed at a plot of wild asters.’
- ‘Crabgrass and plantain are an indication of acidic soil, while wood asters and poppies prefer alkaline soil.’
A radiating array of microtubules associated with a centrosome in a dividing cell.
- ‘Such abnormalities can be due to abnormalities in the number of asters and spindle structures at earlier stages of meiosis.’
- ‘Before mitosis, the centrosome becomes duplicated and the daughter centrosomes move to opposite sides of the nucleus and form asters.’
- ‘Meiosis is completed shortly after ovulation, concomitant with the formation of an extensive sperm aster nucleated by the sperm-derived centrosome.’
- ‘Each centriole now consists of a pair of protein bodies surrounded by radiating strands of protein called the aster.’
- ‘The most interesting aster configuration occurs when the spindle is parallel to the surface.’
Early 17th century (in the sense ‘a star’): via Latin from Greek astēr ‘star’.
