I have done some research, and have found that not only are Thompson and Morgan seeds very good value (generally, you get more seed per packet, often for less money) but also they have a very good germination rate. (Often 100%). Whilst there are rules about the germination rates for vegetable seeds, these do not apply to flower seeds. However, Thompson and Morgan also rate highly for the germination of their flower seeds.
Thompson and Morgan seed catalogue is one of the best for the information they give for each of their packets of seeds. Not only do they list the height, spread and general descrition of the plants, they also give information about the type of soil conditions required, the amount of sun and also the number of days required for germination of seed. They also give a ‘green finger guide’ axplaining the level of experience and care required to get the best results. Should you need to soak seed for optimum germination, or any other treatment, they list that too. In fact, it gives just about all the information you could probably want. And on top of that, they print pictures of almost all their plants.
I have been growing plants from Thompson and Morgan seeds for over 10 years and have made a habit for keeping their catalogues which I use almost as an encyclopaedia. (I also use conventional plant encyclopeadias but they do not give specific information about the cultivars and varieties supplied by Thompson and Morgan.)
The seed catalogue is arranged in such a way that it is easy to find a specific plant should you want to. The main part of the catalogue is in alphabetical order first for flowers, and then for vegetables. in the front of the catalogue are pages devoted to new varieties for the year, then for specific types of plants such as patio plants, grasses, annual plantrs, perennial plants and wildflowers – useful if you are not sure what you want but do not have the time, or inclination, to search through lists of plants. The pictures are attractive and helpful, although as with every other plant catalogue, occasi0nally, the colours are not exact. This particularly applies to blues.
In recent years Thompson and Morgan seed catalogue has started to include items allied to the growing of plants such as pots, propogators and seed trays. They are also selling nematodes which are natural pest control which is safe around children and pets.
All in all, I have no problem in recommending any gardener, whether highly experienced or new to the activity to use the Thompson and Morgan Seed Catalogue as a primary source for buying seeds and other gardening essentials.
