What wouldn't you grow again...

Grand Forks, BC(Zone 5b)

It's September 1, and we start the downward spiral toward autumn. Although I have tried to plant mostly perenials in my gardens, I am still a sucker for those lovely, instantly gratifying annuals in hanging baskets and pots.

Every year it seems there is one or two that have been recommended or looked so lovely on the garden tags, but ultimately are a disappointment. Here are a few that I wouldn't grow again.

1. Verbena Hybrid (Superbena Burgandy) They grew far to big for the hanging baskets I grew them in with other plants. But the biggest problem was the mess they leave with spent flowes falling all over the deck. It was a Proven Winner, but it proved to be a disappointment and I pulled them out by the first week in August.

2. Impatiens. Just can't grow them anymore. :( I fell for the miniature size Rose appearance of these paticular plants. Lost one right away in the spring, and the other sat lanquidly in the pot, not growing much, with 3/4 of the blossoms blasting in bud before I got IMPATIENT myself and chucked it.

3. Nolana (Little Bells) These little guys (had them in orange and yellow) just didn't perform well, and all of them died off in the baskets before mid summer.

4. Double Cascade Blue Petunias (Priscilla) These plants were recommended here on DG early in the spring. I was really disappointed with them. I just couldn't keep up with the deadheading as there seemed to be more than normal. I also was disappointed in the amount of cascading they did. I am used to single Wave petunias that can cascade a foot or more. These ones took a long time, but only hung from the baskets a few inches. They are still growing and from far away look not too bad, but I like to keep petuniuas clean and deadheaded and I simply had to give up trying to eliminate the sticky dead flowers. Last time for them!

How about you? Was there any plants you grew this summer that you wouldn't grow again.?

I seeded Cosmos double click Rose Bonbon.
The pictures in the catalogue show nice fully double flowers.
The flowers turned out to be like bad examples of the seashell cosmos.
I did get one somewhat double flower which looked more like a flatter dahlia flower.
These seed dealers do not grow the new cultivars out over enough years before they place them in their catalogues.

I seeded a poppy which was called a yellow poppy in the title in the catalogue.
The description then says it is "almost Yellow" as it is a creamy colour.
The flowers are pure white. Not even a hint of creamy.

The "White Italian" sunflowers are a nice soft yellow colour.

The petunia Superbissima Mixed are very odd, but pretty flowers. It is one that needs to be deadheaded and doesn't really cascade, so won't do those again.

I tried the Ptlotus Joey seeds. The plants remained short, bloomed for a bit but nothing spectacular and not worth the space to start early indoors.

I won't overwinter cuttings of Impatiens. The new ones I bought did well, but not the cuttings. There are other things too, but I'll have to think about the answers.

Have used cleome, purchased as plants. It's a very pretty annual, which maybe could be described as architectural. The problem is that it is a very heavy seeder and has to be weeded out, when planting something else, the following year.

Calgary, Canada

Cleome is an under used plant. I have grown the annual type of cleome from seeds.
This year I grew Cleome serrulata which is supposed to be a perennial. It has not gone through a Calgary winter for me. It is not as spectacular as the spinosa kind and it has smooth stems---not the prickly ones of the annual. They are both good winter sowing candidates as they need oscillating temperatures for germination.
Cleome serrulata has mauve flowers which have the stamens poking outside the petals.
It is also called Rocky Mountain bee plant.

Interesting Caroline,

Like the idea of the smooth stems
and, of course, mauve.

Is there any variety of Cleome from which you can control the spread of seeds? I gave up growing it because there were so many that I couldn't get them all clipped off and I had so many volunteering in my garden the next year that it got out of control.


Calgary, Canada

I grow them in pots so reseeding has not been a problem for me.
My problem is that people come in to my driveway and help themselves to the seeds.

How cold does it get there? If they reseed in cold climates then perhaps I can add them to my fall seeders list. Or at least do some direct in the fall and some as a winter sow in March.

Just read for Toronto, the average winter temperature is around -6 degrees Celsius, with it sometimes reaching -10 degrees Celsius. We're between
Lake Ontario and Lake Simcoe and it's a bit colder. We definitely have considerably more snow than Toronto, almost always with standing snow all winter.

Grand Forks, BC(Zone 5b)

It would seem, the milder the temps in the winter, the more snow you get. We hover around the freezing point for most of the winter with occassional cold blasts, but we do get dumps of significant snow, with the majority melting away in a couple days. Can be a challenge keeping the perenials with a good covering of snow throughout the season.

Interesting to hear what other gardeners, in other regions, have to contend with.

Do predominantly perennial gardening myself, extending the early part of the season with bulbs. Go to Florida for a bit in winter, but seems our cold climate gardens are much more interesting than those down there.

Oh absolutely! Friends in Arizona are in awe of the Plants and Flowers we can grow here.

I would never again grow Nigella - one plant purchased 5 years ago when we bought this house, and the darn thing pops up all over the place in my gardens. The flowers don't last very long, and it's a rampant self-seeder.

Calgary, Canada

Nigella is better behaved in Zone 3. Reseeds ,but not invasively.
I guess there are some benefits to cold climate gardening.

Two off my list are Galliarda 'Green Wizard' (very unspectacular and takes alot of space) and coreopsis 'Mahogany Midget' (ratty form and the colour is more orangey/bronzey than mahogany IMPO)

Sweet Peas. just the every day garden variety Sweet peas. I would like to grow them but don't have the knack. I can grow lots of more difficult plants, but sweet peas aren't sweet for me.
