O’Toole’s Garden Center - Westminster, CO (Denver)

May 17 – 18, 2025

For the first time in over 15 years, Tomatomania again reaches outside California borders to excite Tomatomaniacs in another U.S. state! We will join hands with O’Toole’s Garden Centers of Colorado to host their first-ever events (at both locations) on May 17 & 18 this spring!

We don’t take this expansion lightly and wouldn’t move in this direction at all if it weren’t for a record of excellence and hard work that we think is consistent with our message and the energy of TOMATOMANIA!

Local, Colorful, Knowledgable. We like that. O’Toole’s takes pride in describing itself with those three words and they’ve been working diligently to make themselves Denver’s best nursery for over 40 years. This season we’ve strategized with them so that they will be able to expand all their amazing green and garden offerings with over 75 varieties of unique, rare or classic tomato varieties.

At O’Toole’s you’ll get expert advice from their amazing staff and find everything needed to produce a colorful and exciting bumper crop. We know O’Toole’s will become Denver’s most TOMATO-centric garden supply venue this year.

Mark your calendars! Tell your friends!

Join other Denver-area Tomatomaniacs on the 17th and 18th as they converge on the nursery sites in Lakewood and Westminster at the start of the gardening year to swap stories, info and compare favorites..

It’ll be a tasty summer garden season and you’re certain to achieve tomato success!
