Grant Flower was born in Salisbury, Rhodesia and was educated along with his brother Andy at North Park School where they were the best players in their age groups. Although always an allrounder, he bowled seamers in his early days and his bowling was rated more than his batting. It was in high school, at St. George's College where he changed to spin bowling.

In the summer of 1990/91 his elevation to a professional cricketer was confirmed when he was employed by the Zimbabwe Cricket Union. His debut first-class game for Zimbabwe came against England A. In his second match he opened the innings and was rewarded with a fifty adding what would be the first of many century partnerships with his brother Andy.

At just 19, Flower was part of the 1990 ICC tournament where the winner would qualify for the World Cup. Zimbabwe would go on to win the competition with Grant Flower scoring heavily in the early games. Had they not won the competition it is likely that Zimbabwe would not have made their rise to Test cricket, at least not until much later. Grant Flower missed out on the 1992 World Cup due to injury. In 1993 Grant spent a season in England with Widnes Cricket Club in the Manchester and District Cricket Association.

Test career

After the World Cup Zimbabwe were promoted to Test status and Flower was unanimously selected to play against the Indians for the Inaugural Test match. On a flat pitch, he opened the batting for his country and dominated in a 100 run opening stand. He would go on to score 82, falling short of a century on Test debut. Zimbabwe again met the Indians this time on their home turf and again fell just short of a maiden Test century when he fell for 96.

Pakistan toured Zimbabwe in 1995 and in the 1st Test Flower finally scored his maiden Test century. Not content, he went on to register double hundred. He hit only 12 boundaries and faced 523 balls as Zimbabwe scored a massive 4/544 declared. His innings would help Zimbabwe to win their first ever Test match as they won by a convincing Innings and 64 Runs. He would continue to haunt the Pakistani side, scoring his second Test century at Sheikhupura Stadium in Pakistan.

In 1997 Flower became the first Zimbabwean to score a century in both innings of a Test match. Playing against New Zealand in Harare, he scored 104 and 151. A year later he scored his 5th Test century, an innings of 156 not out at Queens Sports Club against Pakistan. He would suffer a form slump after that innings, not scoring a 99 for 33 innings including 6 ducks. On 25 November 2000 he ended his slump with a fine 106 against India and would go on to score 4 50's in his next 6 innings.
