Yellow Leaves, Red Leaves, Pretty Leaves, Dead Leaves

Fall color @TacomaWA 14oct07 LAH 015You probably remember learning about fall color when you were in elementary school. You know that leaves turn colors before they fall, and it had something to do with chlorophyll. But when is the last time you really thought about fall foliage from a botanist’s point of view?

As gardeners, we want to know which plants turn which colors so we can use them effectively in the landscape. Here in Colorado, most of us know that aspens turn yellow golden, Gambel’s (scrub) oaks become a flaming reddish orange, and burning bushes (Euonymus alatus) shine in stunning shades of fluorescent pink, purple, and red. But why exactly do they do that? And how?

Ditch this Dame

Worth growing for its delicious ­­­­­­fra­grance­ alone, dame’s rocket also offers showy, long-lasting flowers and is as trouble-free an herb as you could ask for. Its multitude of common names attests to centuries of cultivation in gardens and to the high regard in which it has been held. (Mother Earth Living)

Hesperis matronalis_Dame's Rocket_ColoSpgs-CO_LAH_7355How can you resist such a glowing recommendation? It’s true that dame’s rocket is all these things, but it is also an invasive outlaw, wanted dead, not alive. Like any most-wanted suspect, Hesperis matronalis hides under a plethora of aliases: damask violet, dame’s-violet, dames-wort, dame’s gilliflower, night-scented gilliflower, queen’s gilliflower, rogue’s gilliflower, summer lilac, sweet rocket, mother-of-the-evening, vesper flower and winter gilliflower, to name a few. But not matter what you call it, it’s against the law to grow this plant in Colorado.*

A Garden for Good Bugs

Monarch Butterfly_ChicoBasinRanch-CO_LAH_8874Why would I want to invite insects into my garden? Don’t most homeowners want to get rid of the bugs? It’s true that some insects cause major problems in a landscape, chewing indiscriminately and leaving behind a trail of devastation. But don’t let a few bad guys ruin it for everyone—there are plenty of insects who can live harmoniously among our plants. Some, such as bees, more than earn their keep. And who doesn’t enjoy a garden full of butterflies?

Sweet, Sweet Honeysuckles

I sat me down to watch upon a bank
With ivy canopied and interwove
With flaunting honeysuckle. (John Milton)

Lonicera sempervirens_Honeysuckle_DBG_LAH_6903Mention honeysuckle, and we think of green hedgerows, sultry summer days, and childhoods spent picking the flowers and putting them in our mouths to suck out the sweet nectar. There are around 180 species in the genus Lonicera. Fast growing and tolerant of inhospitable conditions, honeysuckles have much to recommend them. Many are valuable landscape plants able to withstand Colorado’s challenging conditions while presenting us with beautiful flowers and berries adored by birds.
