An easy self-seeder - Torenria

Back in early September, I had the backyard garden re-do. Just a few weeks afterwards, I spotted numerous torenia seedlings growing all over the deck. Hubby and I spent our morning coffee breaks re-planting the seedlings to cover the bare patches of soil at the base of other trees.
This week, these torenia plants are blooming cheerfully.


I remembered buying two baskets of them, one dark violet and one pink, more than 10 years ago. After many seasons of self-seeding, now I noticed there are four different colors.
A dark violet with purple center.


A dark violet with off-white center.


A lavender with off-white center.


And a pink with white center.


Don't you think they look pretty?


They are so easy to care for, in fact, they just need some water. And they self-seed so voluntarily, too. What else would you look for in a ground cover?
