Rare Hardy Succulents

Precious, Tough and Beautiful

There are many lovely hardy succulent plants that are commonly grown in gardens all over the world.

All across Europe, North America, and even in Australia there are xeric gardens, rock gardens and troughs filled with alpine plants and hardy succulents.

Once the taste is formed for these incredible plants, it becomes an obsession to grow more of them.

Orostachys and Rosularia are but two of these rare hardy succulents.

Orostachys has been identified as the most hardy of all plants that use the Crassulacean Acid Metabolism, or CAM system where they can live and actually photosynthesize at very low temperatures, even as low as -40 degrees Celsius.

You hardly ever find these kinds of plants in regular nurseries and garden centers as they are only known to avid collectors of uncommon plants.

My collection of hardy succulents, rare and otherwise, continues to grow as I find out more about them and scour the internet for sources.

Here are some of the rare hardy succulents on my wish list:

Once you have some experience with Sempervivum and Jovibarba, move on to these more demanding additions to the xeric garden.

Virtually all Orostachys are worth growing – although they have quite particular requirements and will pout if these aren’t met, more and more succulent plant gardeners are taking up the challenge.

Orostachys fimbriata – a beautiful soft green with the lowered center typical of the genus, and changing to a cranberry colour as colder weather arrives in the fall.

Orostachys eburnea – the long slender outer leaves encircle the sunflower like center.

One of my favorite rare hardy succulents, Orostachys spinosus, although challenging to find the right conditions and placement will reward the committed with a tall bloom stalk covered with creamy white blossoms.

The tiny green Orostachys minuta is sometimes listed as a subspecies of O. spinosus.

See this interesting post about Orostachys pollination for more information, and some really spectacular pictures of the flowers.

Sadly, once the seeds set the rosette will die as these plants are monocarpic, so collect the seedpods to start a new crop with seed propagation.

Rosularia of many types have long been grown in rock walls, rock gardens and trough gardens but only recently have they caught the fancy of less cliquey gardeners. As a complimentary plant to taller growing alpine plants, hardy succulents and drought tolerant perennials they are unmatched.

As an added bonus, they are polycarpic – meaning the rosette lives on after flowering to bloom again.

Most if not all the other hardy rosette forming succulents have the tendency of dying after flowering, making it a challenge to keep their beauty going in the garden.

Rosularia sempervivoides – named for it’s similarity to its cousin, the Sempervivum, this species has striking red to dark pink flowers on long arching stems over pale blue rosettes.

Rosularia rosulata - I’ve been fortunate to obtain seed through a seed exchange with the Alpine Garden Club of B.C. which holds this event every year.

The seed exchange is included in the cost of membership which is $25.00 annually – well worth the price.

I highly recommend joining alpine gardening clubs, as they are among the most generous of gardeners, their only wish to make more highly obsessed gardeners out of novices.

As you gain more knowledge and experience of all succulent plants I hope you’ll join me in the quest to grow more of these rare hardy succulents as they leave the realm of specialty growers and nurseries and become more commonly grown.
