Tanacetum Parthenium ‘Tetrawhite’

Trial: Annual

Years Trialed: 2000

Good Qualities:

Good filler flower (2); Nice size flowers; Uniform, clear white, strong stems, yellow disk, mild fragrance, highly floriferous; The best one of the three Tanacetum trialed, traditional white flower color and double appearance; Big plant, long stems; Good flower dusters.


Strong stems but most were bent; I would recommend fall seeding (Zone 7.5) as the stems would have been longer and flowers more prolific; May be susceptible to Aster yellows; I just can’t grow because of Asters Yellows; It attacked the majority of the planting; Growth habit not uniform, flower is open and a bit wild looking.


This crop seemed to do better in straight soil than in black plastic mulch; Florists’ preferred this cultivar over ‘Snow Crown’ and ‘Summer Spirit’; Need one layer of support-sometimes two; We had 7 tanacetums in trial this year, all were quite similar except bloom times and plant height; Vase life – 7 days.
