I got a pineapple at the grocery store and saved the crown to start a new houseplant. All trimmed and now just let it scab over for a week or so before potting it. Pineapples are epiphytic bromeliads and really easy to grow but they do get up to 4 feet across so it's destined to be a patio plant. This top wasn't as fresh as I'd like so I hope it takes.
