While aster are unremarkably associate with the autumn garden , Frikart ’s aster ( Aster x frikartii ) blooms during the summertime months .   A loanblend of ItalianA. amellusand HimalayanA. thomsonii , this plant is a welcome addition to the mid - summertime assorted mete .   Starting in June or July , it puts on a show that lasts until late summer or other fall .   Although not native to this country , Frikart ’s aster is well comport and non - invading .   It forms a 2- to 3 - foot marvellous , loose , bushy pitcher with dark green leaf and 2- to 3 - column inch all-embracing gamy - reddish blue blossoms .   It favour full sun to partial specter and tolerates dry soil .   splendid drainage is an inviolable must for this plant , specially in the wintertime .   This drought - liberal works enjoy a long bloom period and , if dead - headed , can continue blooming well into downslope .   When deadheading , be careful not to cut off the bud of new flowers that are forming next to the drop blooms .

Four cultivars of Frikart ’s aster were make grow in the 1920s by German hybridizer Frikart :   ‘ Wonder of Staffa ’ ( or ‘ Wunder von Stafa ’ ) , ‘ Monch , ’ ‘ Jungfrau ’ and ‘ Eiger . ’    Of the four , the two most commonly available   in this country   are ‘ Monch ’ and ‘ Wonder of Staffa . ’    Both have   daisy - like blooms   with lavender - patrician rays and yellow center .   ‘ curiosity of Staffa ’ bloom earlier than ‘ Monch ’ and is taller with a promiscuous habit .   It has paler lilac-colored - dismal heyday that combine well with deep blues and yellow in the landscape painting . According to the Thomas Jefferson Center for Historic Plants , ‘ Wonder of Staffa ’ was praised in 1939 as “ one of the most constant blooming plants in existence produce freely branching sprays of clear lilac-colored - aristocratical efflorescence in lavish profusion . ”   The color harmonizes particularly well with deep dark glasses of lavender - downhearted and violet .   ‘ Homestead Purple ’ verbena is an excellent comrade as well as magenta - colored globe amaranth ( Gomphrena globosa ) .   Another sound companion industrial plant is ‘ Grand Parade ’ bergamot mint ( Monarda didyma ) with its cryptic reddish blue color .

Frickart ’s aster can become floppy as the season pass on .   Cutting it back in May or June can better the growing use but will delay flowering .   Toward the end of the growing season , the foliation be given to become thin , so it is wise to veil its stalks with a lower - develop plant .   Deep purple petunias are idealistic for this purpose and offer a sensational demarcation with the paler aster blossoms .

Although sturdy to Zone 5 , Frikart ’s aster appreciate being left standing during the winter months and then skip back in outflow .   It may be propagated though cuttings or division in the give .   grow from seed is possible but not recommended because the new plant will not be true to colourise .

While no works is ever completely deer proof , Frikart ’s aster is generally not bothered by either deer or rabbits .   It also has adept mildew - resistant qualities .
