If you have been gardening long enough in one place, odds are you have made a few mistakes.
I certainly have. There are times I purchased and planted something in a spot because it looked good there at that moment, without taking into consideration the light, drainage or space requirements.
I have mint that for years was perfectly well behaved until the year it wasn't. I spend hours now cursing myself, cutting it back to make room for anything and everything else in the bed it dominates. It is a lot of work but that smell! Is there anything more delicious than working with mint? Maybe I let it go just a little bit on purpose. Certainly the bees are happy when I do.
There were times when capricious weather did my plants in. A colder than usual spell took a tecoma stans I couldn't shelter adequately, and a dry spell eliminated a New Guinea impatiens because I decided long ago not to try to keep anything that needed daily watering. Not to mention the free lance landscaping courtesy of our neighborhood deer.
Occasionally, it all goes well. Some of the time because I made a well informed choice, more often than not because I got lucky.
This year the basil I seeded in with the wildflowers has tolerated my neglect and is doing quite well.
This year one of several morning glory vines I planted survived long enough to come into its own. I can't help it y'all, I get a little weak at the knees over blue flowers.
This year, out admiring my blue flowers close up, I was reminded how glad I am to have gathered the seeds from a thick stand of purple ruellia in a public parking lot bed (after getting permission from the owners). I like the pink and it has replanted itself liberally. The purple seems more well mannered however and I do love the color.
Last but certainly not least, once again this year, I fell back in love with my Texas Kidneywood (Eysenhardtia texana) for its delicate leaf structure and its wonderfully fragrant white flower spikes.
It has persevered through cold, heat, drought, deluge, crowding out and severe trimming back. Best of all it keeps coming back for more. Sort of like I do.
