In addition to tolerating low water, succulents tolerate poor or shallow soils, windy conditions, steep slopes, and rapid changes in temperatures. In fact, succulents thrive in these conditions so common in Colorado.
Accordingly, what succulents can grow outside in Colorado?
You can have a gorgeous AND cold hardy succulent garden!
There are two main varieties of succulents that can tolerate freezing temperatures, Sempervivums (commonly called hens and chicks) and Stonecrop Sedums. Most will tolerate temperatures down to -20 degrees Fahrenheit.
Keeping this in consideration, how do you keep succulents alive in Colorado?
Two keys to succulent success have to do with sun and water. Avoid placing or planting succulents in full sun. Tender leaves can burn in intense sunlight, so grow them where they can get morning sun and partial shade in the afternoons. Allow the soil to dry slightly between waterings.
Where should I plant succulents outside?
Succulent Outdoor Plants
Sedum and sempervivum are easy to grow and adaptable to bright, sunny locations or even slightly dappled areas. Whatever types of plants you choose, succulents need well-drained soil. They can thrive in cracks and crevasses, rockeries, and sandy or gritty soils.
Hardy succulents: Tolerate frost and can stay outdoors through below-freezing temperatures. They’re ideal for year-round, outdoor growing. In fact, hardy succulents grow better outdoors than in!
Generally it’s best to wait until after the last frost and when the nights don’t drop below 40F. While you could plant some succulents outside before then, you’ll find the best success with planting when the weather is warmer. Avoid waiting until summer though, as the heat can cause just as many problems as the cold.
A common question is can succulents live outside? The short answer is yes! They thrive in sunny locations with warm, dry climates and can tolerate some neglect, so growing succulents outdoors is a great option. Grow succulents in-ground, in pots, or tuck them away in unexpected planting spots.
A little rain won’t harm healthy succulents and cacti. In fact, even a lot of rain can be beneficial to your garden. As a general rule, succulents prefer infrequent but deep water. A heavy rain might be just what your plants need to look perky and vibrant after a dry or hot spell.
Many of Colorado’s xeriphytic natives are succulents, such as sempervivums, agave, ice plant, and sedums. Cacti are identified by their aeroles which develop into spines or flowers.
Cold hardy succulents are those that are tolerant of growing in temperatures that are freezing and below. Like soft succulents, these plants store water in their leaves and need much less watering than traditional plants and flowers. Some cold tolerant succulents live happily in temperatures below 0 degrees F.
But are succulents perennial or annual plants? There are many types of succulents, but most of them are perennial, which means that they can last for many years. However, some kinds of succulents are annuals, which means that they only grow for a single season and then die.
