Ten Neat Things about Blue
1. Blue impatiens. Impatiens namchabarwensis is a semi-woody, branching, one-foot tall plant with delicate true-blue blooms that was discovered in a small region of the Himalayas in 2003. Today I received notice that Dominion Seeds has a limited selection of plants available for purchase by mail order. It's a tender perennial, so you could either treat it as an annual or, given the $15 apiece price tag, try overwintering the fleshy roots indoors.
2. Blue nasturtium. Tropaeolum azureum is a species of nasturtium with a lovely blue colour tending toward violet. It's from Chile and was brought to Europe as early as 1843 by a collector named William Lobb. I'm not sure why, but it's devilishly difficult to get hold of; I know of no Canadian dealer.
3. Bluest blues. Blue is the most difficult colour to breed into plants. Blue pigments have a tendency to shift toward pink, purple and red in different pH levels.
4. Blue mushroom. Lactarius indigo is a remarkably blue wild mushroom that grows in coniferous forests of eastern North America. When broken or cut, it exudes a blue milk that slowly turns green after being exposed to air. Not sure who figured it out, but this mushroom is edible.
5. Blue butterflies. The beautiful iridescent blue colour of some butterflies tends to come not from within-from actual pigments in the insect-but from refraction of the scales on the wings. The oranges and yellows, on the other hand, are pigmented scales.
6. Blue frog. The okopipi frog of Brazil is a poison dart frog that is a lovely cerulean blue with black spots that differ from one individual to the next. It exudes poisons that will paralyse or kill a predator that doesn't heed the warning blue colour.
8. Blue for spring. Blue is the colour of grape hyacinths, one of the loveliest flowers of spring. It looks stunning against the bright yellow of daffodils.
9. Blue for shade, blue for sun. Many blue flowers are shade tolerant. Some examples: forget-me-not, browallia, Siberian bugloss, periwinkle, Jacob's ladder, some pulmonarias, baptisia, and violets. For sun, try Victoria Blue salvia, many veronicas, many campanulas, delphimium, blue flax, blue pansies, many cranesbills, blue asters, nemophila (baby blue eyes), convolvulus, and borage to name just a few. Lobelia prefers part shade.
From top to bottom: (1) A rare royal blue flower. (2) The edible Lactarius indigo. (3) A flutter of blue butterflies. 4) The beautiful yet lethal dart frog that hails from Brazil. (5) Sure it make look cool to children...but for adults, milk should only be consumed when white.
