The present invention relates to compositions for controlling plant and flow er moisture transpiration and thereby extending the period of time in which cut flowers can be displayed before senescence produces a flower which has exceeded its aesthetic value. The compositions of the present invention comprise: a) from about 0.1 % to about 20 % by weight, of a homopolymer or copolymer comprising monomers having formula (I) wherein each R1 is independently hydrogen, C1-C12 alkyl, C1-C12 alkoxy, phenyl, substituted phenyl, benzyl, substituted benzyl, carbocyclic, heterocyclic, and mixtures thereof; R2 is hydrogen, halogen, C1-C12 alkyl, C1-C12 alkoxy, phenyl, substituted phenyl, benzyl, substituted benzyl, carbocyclic, heterocyclic, a nd mixtures thereof; X is hydrogen, hydroxyl, halogen, -(CH2)mCH2OH, -(CH2)mCOR , - (CH2)mCH2OCOR', wherein R is -OR', -N(R')2, -(CH2)nN(R")2, and mixtures thereof; each R' is independently hydrogen, C1-C8 alkyl, C2-C8 hydroxyalkyl, - (CH2)nN(R")2, and mixtures thereof; wherein R" is independently hydrogen, C1 - C4 alkyl, and mixtures thereof; the index m is from 0 to 6, the index n is from 2 to 6; b) from about 0.01 % to about 5 % by weight, of a surfactant; andc) the balance carriers and adjunct ingredients.
