There were six original 7 inch Bread and Butter plates in the Botanic Garden range, when it was launched in 1972:

They were the Spanish Gum Cistus, the Trailing Bindweed, the Meadow Saffron, the Citron, the Daisy and the Barbados Aloe.

Most motifs were from The Universal Herbal, by Thomas Green,  published ca. 1820:

The Meadow Saffron, here seen with the original:

The Trailing Bindweed has differences in the position of the lettering:

At one point the Trailing Bindweed had a butterfly change, the colorful old butterfly was replaced by a yellow and blue one:

The oldest versions of the Bread and Butter plates have the script writing, later versions have other lettering:

Here is the original set with the newer lettering:

Very soon there was a seventh motif on the Bread and Butter plates, the Spring Gentian:

Spring Gentians now are rare and hard to find. A pity, it is such a lovely motif, with its small, bright blue flowers.

Later Bread and Butter plates were

the Ivy Leafed Cyclamen, the Barbados Cotton Flower, the Blue Primrose, Snow-Drop and Crocus, the Pansy, the Fuchsia, the Small Narcissus, the Rhododendron and the Barbados Cotton Flower.

As can be seen, there are two versions of the Barbados Cotton Flower, one with three flowers and one with two:

There are also two versions of the Snow-Drop and Crocus, he older one being lighter, whereas the newer version has darker colours:

On the occasion of the 25th anniversary of Botanic Garden special sets were for sale, comprising of one cup and saucer and one bread and butter plate:

There were two different plates, the Snow-Drop and Crocus and the Small Narcissus. They had the special anniversary backstamp:

And here is my latest, the Arborea:

There are several motifs that occur not only on Bread and Butter plates, but also on Salad Plates, or on Dinner Plates, or on all three, such as the Pink Parrot Tulip :
