Amwoga KhalwaleFlorida avocados occupy a distinct and often overlooked corner of the avocado world, since the vast majority of avocados sold in American supermarkets are the small, bumpy-skinned Hass variety grown primarily in California and Mexico, while Florida has cultivated an entirely different tradition built around smooth-skinned, often much larger fruit that stays green even when … Read more
Red sunflowers represent one of the more surprising color breakthroughs in ornamental flower breeding, since the classic image of a sunflower is so thoroughly associated with bright, sunny yellow that many gardeners are unaware red-toned varieties exist at all. These red and mahogany tones actually come from the same anthocyanin pigments responsible for color in … Read more
Pineapples are among the most widely traded tropical fruits in the world, grown across more than 90 countries and generating a global market worth tens of billions of dollars each year. A single pineapple plant takes roughly 18 to 24 months to produce its first fruit from a newly planted sucker or crown, and once … Read more
Black roses share the same essential secret as blue roses: they do not truly exist in nature, since no rose produces a genuine black pigment, and every flower marketed as “black” is actually an extremely dark red, maroon, or deep purple cultivar whose color intensifies to the point of appearing black under the right conditions. … Read more
Blue roses hold a unique and almost mythical status in the world of flowers, since no rose in existence, with one very recent and heavily engineered exception, actually produces true blue pigment. Roses lack the natural genetic pathway to synthesize delphinidin, the blue pigment found in flowers like delphiniums and pansies, which means that every … Read more
Green roses represent one of the rarest and most genuinely unusual colors in the entire genus, since roses lack the natural pigment pathways needed to produce true green petals, and every rose gardeners and florists call “green” is really achieving the effect through one of a few different biological tricks. The most historically important of … Read more
Orange roses are a relatively recent arrival in the long history of rose breeding, since the original wild roses that gave rise to modern cultivars existed only in shades of white, pink, and red, with yellow not appearing until the early 20th century and true orange following only after breeders learned to blend yellow and … Read more
Purple roses occupy one of the most elusive and hard-won corners of rose breeding, since no rose in cultivation carries a truly blue or violet pigment, and everything gardeners call “purple,” “lavender,” or “mauve” is technically a diluted, cooler-toned expression of the same red and pink pigments found throughout the rest of the genus. Because … Read more
Red roses stand at the very heart of rose symbolism, representing passion, love, and desire more powerfully than any other color in the genus, and they have been bred across nearly every classification recognized by the American Rose Society. A mature hybrid tea or grandiflora red rose typically reaches 3 to 6 feet tall with … Read more
Pink roses hold the distinction of being one of the oldest rose colors in cultivation, since many of the earliest known garden roses bred in Europe and the Middle East centuries ago were naturally pink or rose-toned long before yellow, orange, or true red hybrids became widely available. Today pink roses are produced across nearly … Read more
