Altum's Horticultural Center & Landscape

From the first tree in 1958 to the spectacular, fanciful, and charming landscapes that followed, Bob Altum worked with purpose and passion, building beautiful gardens and lasting relationships with his clients.

For 50 years, he and his team have started every job with the most robust, vibrant plants from handpicked local suppliers who know the soil and stake their reputation on quality. Bob appreciates the “local mentality” because he practices it himself, investing his time, attention, and resources in giving the best to his clients. This is how he earned the trust and business of generations, who learned, one after the other, that Bobʼs creativity, personal touch, and painstaking perfection were what made—and continue to make—the Altumʼs name.

Today, the Altum family practices Bobʼs garden principles from its expansive horticultural headquarters nestled between Zionsville, Carmel, and Indianapolis, Indiana. This is where we bring ideas to life. Because we share Bobʼs belief that there will always be two things worth building: gardens and relationships.
