I take it in for winter, out for summer. Blew me away when it started to produce actual fruit. I don't know how long it takes to mature and would like some input. Attached a current photo.

Prolonged cold above freezing retards growth, delays maturity and causes the fruit to be more acid. How Long to Get Fruit. Growing a pineapple plant from the top of a mature fruit can take upwards of 2 1/2 years before the plant is mature enough to blossom. If growing from suckers, it can take 1 1/2 years, and from slips, roughly one year to maturity. Query: how long for pineapple to mature
