How to Grow and Care
The genus Hylotelephium may not be familiar to many of you, but in fact most gardeners have seen or are growing these succulents without knowing it. That is because this genus was once part of the genus Sedum. Species in the genus are popular garden plants, known as "Border Stonecrops" or "Border Sedums".
Hylotelephiums will thrive in conditions that many other plants thrive in, but will do just as well in less hospitable areas. These plants are ideal for that part of your yard that gets too much sun or too little water to grow anything else. They also grow well in containers.
Border Stonecrops prefer full sun. They tolerate some light part shade in hot summer climates, but will produce weak floppy growth when grown in too much shade or in overly rich soils. Plant in an area of your garden that gets 6 hours of sunlight a day.
These succulents succeed in most soils, but prefer well-drained potting mix.
Hylotelephiums are drought tolerant plants. The best way to water these plants is to use "soak and dry" method. Get the soil completely wet and then wait until the soil is dry before watering again.
