ASTELL

astell, mary (1668-1731), english author, was born at newcastle-upon-tyne. she was instructed by her uncle, a clergyman, in latin and french, logic, mathematics and natural philosophy. in her twentieth year she went to london, where she continued her studies. she published, in 1697, a work entitled _a serious proposal to the ladies, wherein a method is offered for the improvement of their minds_. with the same end in view she elaborated a scheme for a ladies' college, which was favourably entertained by queen anne, and would have been carried out had not bishop burnet interfered. the most important of her other works was _the christian religion, as professed by a daughter of the church of england_, published in 1705. aster (gr. [greek: astaer], a star), the name of a genus of plants, given from the fact of the flowers having a radiated or star-like appearance (see below). the greek word also provides many derivatives: e.g. _asterism_ (gr. [greek: asterismos]), a constellation (q.v.); _asteroid_ (gr. [greek: astero-eidaes], star-like), an alternative name for planetoids or minor planets (see planet). the genus of composite plants named aster (natural order _compositae_) is found largely in north america, and scattered sparingly over asia, europe and south america. they are usually herbaceous perennials; their flowers arranged in numerous heads (_capitula_) recall those of the daisy, whence they are popularly known in england as michaelmas daisies, since many are in bloom about that time. they are valuable plants in a garden, the various species flowering from late summer right on to november or december. the only british species is _aster tripolium_, found abundantly in saline marshes near the sea. one of the species, _aster alpinus_, grows at a considerable height on the mountains of europe. some of them, such as _aster spectabilis_ of north america, are very showy. they are mostly easy to cultivate in ordinary garden soil, and are readily propagated by dividing the roots in early spring. the following are some of the better known forms:--_a. alpinus_, barely 1 ft. high, and _a. amellus_, 1-1/2 ft., with its var. _bessarabicus_, have broadish blunt leaves and large starry bluish flowers; _a. longifolius_ var. _formosus_, 2 ft., bright rosy lilac; _a. acris_, 2 to 3 ft., with blue flowers in august; _a. ericoides_, 3 ft., with heath-like leaves and masses of small white flowers; _a. puniceus_, 4 to 6 ft., blue or rosy-lilac; _a. turbinellus_, 2 to 3 ft., mauve-coloured, are showy border plants; and _a. novae-angliae_, 5 to 6 ft., rosy-violet; _a. novi-belgii_, 3 to 6 ft., pale blue; _a. laevis_, 2 to 6 ft., blue-lilac; and _a. grandiflorus_, 3 ft., violet, are especially useful from their late-flowering habit. the china aster (_callistephus chinensis_) is also a member of the order _compositae_. it is a hardy annual, a native of china, which by cultivation has yielded a great variety of forms. some of the best for ornamental gardening are the chrysanthemum-flowered, the paeony-flowered, the crown or cockade, the comet, and the globe-quilled. crown asters have a white centre, and dark crimson or purple circumference, and are very beautiful. the colours range from white and blush through pink and rose to crimson, and from lilac through blue to purple, in various shades. they should be sown early in march in pans, in a gentle heat, the young plants being quickly transferred to a cool pit, and there pricked out in rich soil as soon as large enough, and eventually planted out in the garden in may or june, in soil which has been well worked and copiously manured, where they grow from 8 to 18 in. high, and flower towards the end of summer. they also make handsome pot plants for the conservatory.
