Scopolia carniolicaย var.ย brevifoliaย is rarely found in gardens. It has interesting shinny leaves that develop very early in spring, followed by low-key flowers at a time when few perennials are flowering. It has cream-yellow flowers while the main species,ย Scopolia carniolica, has chocolate-red flowers. The plant pictured here was a gift from my friend at BotanyCa, a great source for rare seeds.

15 Moss Myths Every Gardener Should Know

I love moss on rocks and trees, and even growing on the ground, provided it is in the right spot – as determined by my aesthetic sensibilities. It is not nearly as welcome in the lawn although I don’t really mind having it there. Moss in the lawn is considered by many as a big problem and this has led to a number of myths about moss.

Some people try to grow moss, but that is not as easy as it sounds. Moss is kind of strange that way; some people are constantly trying to kill it, while others are trying to grow it.

My goal for this post is to understand moss better by exploring the many moss myths.

Heirloom Seed Myths – Are They Worth Buying?

What is so special about heirloom seeds? I see a lot of online questions from people looking to source heirloom seeds. Are these seeds really that much better, or is this just another new craze or fad?

People grow their own food mostly to be healthier and they believe heirloom seeds are better for you. Is this true? Do they produce better tasting food, or produce a better yield? What is the real value in heirlooms?

Maybe the attraction to heirloom has more to do with tradition as suggested by this comment; “To the gardeners who love them (heirlooms), it matters that ‘Mortgage Lifter’ tomato came from a man who bred his own tomato plants, selling enough of them to pay off his mortgage”.

Tomato Seed Fermentation – Is it Required?

Is tomato seed fermentation required? There are quite a few methods described on the internet for collecting and cleaning tomato seed, but which one works best? How do we define ‘best’? What works well for a commercial seed company may not be the best option for a home gardener.

A very common option is the ‘tomato seed fermentation’ method. Some say that it is absolutely necessary in order to get a high germination rate, but not everyone uses it, and they still claim to get good germination.

It is also believed that fermentation reduces pathogens on the seed. In this post, I will look at the science behind collecting and cleaning tomato seeds.

Germination Test: How to Test Seeds for Viability

The Germination test measures seed viability and can help gardeners figure out why things are not growing from seed.

Last year my planted carrot seed did not germinate very well. Was the seed still viable, or did I plant the seed too deep? Maybe it got too cold and the seedlings died, or maybe they were eaten by slugs? Did I fertilize enough?

I also collected some tomato and bean seeds last year. I wonder if they are viable? And what about the old seeds I have stored in my fridge; should I use them this year or buy new ones?

These questions can all be answered with a very simple seed viability germination test that you can do at home.
