Either. It matters. Since white is dominant, the allele (saying it is T for white and t for purple) could be either TT or Tt and still come out white. If the white flower is a purebred, then it is homozygous, therefore, TT. However, the flower could be white and be heterozygous.
Being homozygous isn't determined by what plant species it is. It is determined by the gene and how it is expressed. Depending on the plant, being homozygous is different.

Homozygous recessive plant
A. homozygous at two loci (AA & cc).
Homozygous dominant Homozygous recessive and Heterozygous
Do a testcross with a homozygous recessive plant.

homozygous- TT; heterozygous- Tt :)
homozygous
Homozygous dominant would be all Capital letters. Homozygous recessive would be all lower case letters. So...in basic color genetics for horses: A homozygous recessive horse would be aaee A homozygous dominant horse would be AAEE
