What’s Blooming: The Swiss Cheese Plant

by Jack Donovan, Horticulture Intern, Gardens on Spring Creek

Our Butterfly House Monstera deliciosa, also called a Swiss cheese plant, is blooming for the first time in four years!

This perennial evergreen vine is native to Mexico and Central America, growing in Zones 10–12. Commonly grown as houseplants, these plants often fail to reach their full potential. Luckily our Butterfly House provides an ideal spot for this specimen.

Monsteras rarely bloom in homes, because they require conditions and space that approximate their native, rain-forest habitat. Thus, our Monstera is a must see! With a white spadix (a spike that has tiny flowers on it) growing to approximately 10 inches, the bloom will eventually produce an edible fruit that tastes like pineapple and banana. The plant’s perforated “Swiss cheese” leaves, called fenestrations, are believed to be an attempt by the plant to capture more sunlight or, possibly, to see their large leaves through high winds undamaged.

Here are three photos of the bloom, starting with a close-up and zooming out to show the enormous size of the plant. Can you still see the blooms in the two larger photos? They are there!

Hornworms by Brionna McCumber

Gardeners in Colorado may find large green caterpillars with an iconic horn on their plants every summer—these are hornworms! Tobacco hornworms ( Manduca sexta ) feed on common garden crops, often leading to conflict with humans. These very hungry caterpillars are defoliators, damaging plants such as tomatoes, peppers, potatoes, and eggplant. While the caterpillars use crops as a food source, which could be seen as negative, the moths provide a critical step in reproduction for the plants via pollination. Carolina Sphinx Moths ( Manduca sexta ), also called Hummingbird moths, are the adult form of hornworm s. They are known for their unique ability to hover mid-flight. Combined with the use of a special elongated proboscis, these moths are especially important for plant species with long tubular flowers that other pollinators cannot access or pollinate. The Gardens on Spring Creek Butterfly House wants to highlight the importance of these specialized pollinators in our...

Winter Watering by Bryan Fischer

O ne of the brightest spots of living on the Front Range of Colorado is its winters. With more than 300 days of sunshine annually, we seldom see extended periods of the grey, chilly, precipitating skies common in so much of the country. It’s not unusual for daily highs to make it above 50 degrees. Much of this we have our elevation and distance from an ocean to thank – our sunlight is more intense than at sea level and our humidity lower, resulting in greater warming during the day compared to regions of similar latitude to our east or near a coastline .  Unfortunately for many landscape plants, however, that same day-night temperature differential spells trouble when paired with our lack of soil-insulating snow cover.  The resulting environment of warm days, frequent wind , and intense sun increases water demand, while low humidity saps the soil moisture reserves that our limited precipitation may provide. As a result, our landscape plants are predisposed to dehydration-indu...

Conifers: Pining for Something Different by Bryan Fischer

Evolving considerably earlier than flowering plants (angiosperms), conifers represent a long-lived and successful lineage of trees classified as gymnosperms. Gymnosperms were among the first true seed-bearing plants and evolved before specialized pollinators existed, so they are typically wind-pollinated. Seeds on these plants are produced between or on scale-like structures (think pine cone scales), rather than in fully enclosed structures, like tomato fruits. Gymnosperm, in fact, is Greek for “naked seeds,” so just imagine what that might imply for the origin of the word “gymnasium” … Long-lived, adaptable and attractive year-round, conifers represent a silver bullet of sorts for our Colorado gardens. Sadly, the overuse of just a few species and cultivars of these plants has given them a bad name. Don’t be put off – judicious use of conifers makes perennial plantings “pop” and provides structural bones during the fall and winter months. Below, find a selection of underused, adap...
