Brownie Troop 299 thought it would make Crofton a more beautiful place.
Someone had other ideas.
The 14 day lilies the 19 girls planted were snatched from their beds at Swann Park before anyone could enjoy the yellow flowers.
"I was riding by to see if any were in bloom yet," recalled 9-year-old Meghan Gregoire, a member of the troop. "And they were just gone. I don't think people should do that. It's really mean."
Last month, the troop spent an hour on hands and knees scooping mulch to make way for the lilies. It was part of the troop's Adopt-a-Park program.
"They were so excited," said Jane Roach, Meghan's mother and a Brownie troop leader. "They all live in the area, and they wanted to see them bloom."
What concerns Crofton leaders now is the $8,000 worth of shrubs and lilies that will be planted at Swann Park at the end of the month.
"This is 14 day lilies. We're talking about thousands of dollars of landscaping that's going to be coming," said Katherine Puhak, a member of the Crofton Civic Association board whose 9-year-old daughter, Andrea, is also a Brownie. "We really need to have the community looking out for the landscaping."
Town Manager Barbara K. Swann said Crofton has had trouble in recent years keeping its plants intact. About five years ago, someone took 400 ground cover plants from a median strip a week after they were planted. In the last two years, shrubs, one and two at a time, disappeared from a landscaped area on Layton St.
"We have no way of knowing if it's spiteful vandalism or someone putting [the plants] in their own backyard garden," said Ms. Swann, who has told the town's five-member police force to be on the lookout for stolen plantings.
"We can probably get more help from the citizens than the police because neighbors are close to the location," Ms. Swann said.
