The Texoma Rainbow Iris Society wants people to get excited about irises. The group will hold its show, “Irises in the Landscape” from 1 p.m. to 4 p.m. Saturday at the Sherman Senior Center, 1500 N. Broughton Street, Sherman. Iris judging will be from 10 a.m. to noon Saturday.

“We wanted to have it on Earth Day because it just makes sense,” Margueritte Ballard said. “We want people to celebrate the Earth with us. We have had several shows but this is the first time we have had one in years.”

Currently, there are about 20 people in the group, but they are looking for new members.

“We want to introduce new varieties of irises,” she said. “We also want to pique people’s interests in them and educate them on irises.”

Ballard said there are many things about irises that people do not know.

“Irises are not bulbs as many people think,” she said. “They are rhizomes. It’s fascinating how they reproduce and grow. They are very easy to grow.”

“Irises come in thousands of colors,” Ballard said. “A grower has to establish a flower for several years before it can become an official iris species or iris variation.”

Ballard said while some society members have thousands of different kinds of irises in their gardens, she just has hundreds of different kinds of irises in her home garden.

“One cool thing we do at the society is ‘Christmas in August,’” she said. “We have a Christmas exchange where we give each other different types of irises. Irises can range from several dollars to several hundred dollars.”
