I've always had sort of a Darwinian attitude towards my plants. Between scorching in the summer, drowning in the winter, and occasionally taking a flying dive off the deck, "survival of the fittest" seems appropriate. I'll do my best by you - but you gotta be able to tough it out.
L is for Lantana
This fellow seems to have grasped the policy. I know a few different plants have been started in that location over the years, some of which received intense, loving care, and still slipped off to the great greenhouse in the sky. (There was that terrible episode with the tomato plants and the mutant monster worms.) But this guy bounced back from last year and blooms like a champion. And then there those plants who, not content with just being decorative, have set their sights on world domination.
M is for Morning Glory
The Borg of the plant world, this critter will reach out a dainty-looking tendril and snag onto anything that holds still, even if for the briefest moment. It swarms upwards, wrapping around other plants, twining along a clothesline, and blankets a wall and everything on it. Resistance is futile, you WILL be assimilated. You wanna admire this beauty from a distance. Or keep moving!
