Wait, this about the Petunias that used to be in the beds above.
Seeds of Petunias are fine, like dust. Apparently seeds shed onto the driveway were scatterered by wind from the northwest during fall and winter and settled into some scant ryegrass from the previous year that volunteererd along the driveway. When Spring came, they sprouted into a bed of their own in a semishaded area that was unplanted in previous years, with scant grass.
Laura Bush is a hardy, reseeding annual variety native to South America. This rugged old-fashioned Petunia variety was bred for its heat and cold tolerance and disease resistance, promoted by TAMU.
Some of my best plants originated at Texas A&M, where much research goes into rugged plants that can stand harsh climates including this hot, humid place. The humidity here this morning was 88%, now down to 80%.
When plants get leggy, I cut back tops by about a third.
Tended, they will last until frost. They started blooming in
March, one of the few cool season annuals that will
continue during hot and humid summer days here.
Two Rose Campion plants came up in the back of the bed, perfect color coordination. I cut stems of ripe seeds and scatterered back there the other day, hopeful of a fuller bed.
This is not a maintenance-free bed. I've been pulling weeds and grass since I noticed an abundance of plants that were not weeds. When I walk by, I pull a few more. Weeds are pernicious and rarely give up. Squirrels planted pecans there that have to be grubbed out. Dogwood seedlings have sprouted. I figure such a pretty bed is worth a little work.
I would have left this area for the mower and never planted here. It was a happy self-seeded event.
Do you let self-seeded areas grow?
