If you're looking for a popular trailing plant that creates great groundcover, then look no further than Blue Chalk Sticks or Blue Chalk Fingers, also known as Senecio mandraliscae, a stunning variety of Curio talinoides var. mandraliscae

This unique spreading blue chalkstick produces pencil-like, blue-green fleshy leaves that form a dense mat and is of great ornamental appeal as one of the most popular and trendy groundcovers.

Native to South Africa, these low-growing blue chalk sticks with thick, 4-inch-long silvery-green leaves give the succulent plant the appearance of a mass of fingers or chalk sticks reaching up to the sky. 

The blechalk stick is a great groundcover and adds a nice color accent to make other plants stand out in a garden or landscape.

Additionally, the blue chalk stick's low-growing and spreading nature helps suppress weed growth, making it an excellent choice for areas that require minimal maintenance.

These plants use their tendrils to latch onto structures and support their growth, creating a stunning vertical display. It can grow up to 18 inches tall and 24 inches wide, forming a dense mat of blue-gray leaves.

You will notice that the leaves tend to curl upward, making it look like it's stretching out for some sunshine. It's like a little garden masterpiece! 

When it comes to flowering, the blue chalk sticks produce daisy-like flowers. In the mid-summer and early autumn, this plant produces small white flowers on top of the foliage. 

But there's more to this blue chalk stick than its good looks; it's also drought-tolerant and incredibly easy to care for, making it perfect for beginners or anyone looking to add a splash of color to a large planter or border area of their garden. It creates a cool blue-green carpet that contrasts with green plants, giving your garden an eye-catching appeal.

When and How to Water Your Blue Chalk Sticks 

As drought-tolerant plants, these chalk sticks Senecio mandraliscae can thrive with less frequent watering, and if you forget to water them for a month or more, they will probably survive just fine.  Make sure to allow the topsoil to dry between each watering session and avoid overwatering, which can lead to root rot. This is especially the case with blue chalk sticks Senecio mandraliscae, as they don't do well in moist soil, which can result in root rot.  

In the spring and summer, during the growing season, your blue chalk sticks plants typically need to be watered every 1-2 weeks, allowing the soil to dry out slightly between waterings. In the fall and winter, during the dormant season, reduce watering to once a month or less, as the plant requires less moisture when not actively growing. 

Watch out for signs of dehydration, such as a pale discoloration and shriveled stem, indicating that your blue chalk stick is consuming its interior water supply.   

Light Requirements - Where to Place Your Blue Chalk Stick Plants 

If grown indoors as a houseplant, place your chalk stick plant directly in front of a west- or south-facing window. If they don't receive enough light, their stems may grow leggy and become paler, and their spines will shorten, so make your succulent happy and give it plenty of light.

For outdoor cultivation, Senecio mandraliscae thrives in conditions with full sun to partial shade. Ideally, the plant should receive at least 4–6 hours of sunlight daily to maintain its vibrant blue-green color and promote healthy growth.

During periods of intense heat, especially in summer, partial shade can be beneficial to prevent stress and discoloration. Excessive sun exposure during the hottest part of the day may cause the leaves to bleach or scorch, which can weaken the plant over time.

Providing adequate light is one of the most important aspects of caring for Senecio mandraliscae, ensuring it maintains its iconic chalky blue hue and compact, sprawling habit.

When grown in optimal lighting, these succulents are highly resilient, requiring minimal maintenance which makes them ideal for drought-tolerant landscapes or rock gardens. 

Optimal Soil & Fertilizer Needs 

The blue chalk sticks Senecio mandraliscae favor very airy, sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and, most likely, root rot. Instead, make or buy a well-draining potting mix, or ideally, use our specialized potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your blue chalk stick succulent plants thrive.

When it comes to fertilizers, balanced (5-10-5) NPK fertilizers also last longer and keep your soil alive by adding other beneficial compounds and microbes that encourage blue chalk stick health and nutrient absorption. So, skip those harsh chemicals and give your succulent some love with some awesome organic fertilizer! 

Hardiness Zones & More 

When growing indoors as a houseplant, they perform best in a range of 65–80°F with bright, indirect light. They are highly tolerant of low humidity, making them a perfect fit for most indoor environments. Avoid placing them in overly humid areas, as excessive moisture can lead to fungal issues or root rot. Proper ventilation and well-draining soil are crucial to maintaining healthy growth indoors.

For outdoor cultivation, Senecio mandraliscae is best suited for USDA zones 9–11, where temperatures remain mild year-round. In these regions, the plant can be grown as a perennial and withstands the occasional temperature dip as long as it stays above 30°F.

If temperatures drop below this threshold, consider covering the plant or bringing it indoors. 

Blue Chalk Sticks are heat-loving plants but can be sensitive to prolonged humidity. In areas with high humidity, ensure proper soil drainage and avoid overwatering, as these conditions can increase the risk of rot. They flourish in dry to moderately humid conditions, making them ideal for Mediterranean or arid landscapes.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.

Thumbs up!
Color: Stainless Steel/Blue/Stainless Steel/red-blue
Amazing watch with fabulous details for any Snoopy fan. Very slim profile for an automatic watch. Colors pop. I wear this watch in the shower and swimming and it's water resistance is on point. The watch also has light-charge lume, which is a wonderful detail. I own several Peanuts x Timex, but this is easily my favorite.

Beautiful Retro Inspired Automatic watch.
Color: Stainless Steel/Black/Stainless Steel/Red Black
First I'd like to start by addressing one of the other reviews. This is an automatic watch so it is wound by motion but it also can be hand wound via the crown. The myota movement (citizen) is rated for about 40 hours fully wound so if used properly and worn daily (and if set correctly) it should run throughout the night and still be the correct time and date when you are ready to put on in the morning. This watch band style is one that isn't used very much any more and requires a screwdriver or tool to open the wedge on the lower latch to move it to the correct place on the band. This is easier to size than most metal watch bands and is much more flexible. Once you set it to your wrist size it shouldn't fall off and the adjustment shouldn't move unless it isn't set properly. It has a latching mechanism that should snap together and hold tight. It can be hard to get used to putting on at first but after a few times you will know how to easily put it on. I've owned a watch band of this style previously on a watch I wore daily so it was okay for me. I'd say that anyone looking at an automatic watch is probably more of a watch enthusiast and already knows the little nuances of owning one. If you are new to watches do your research first. Otherwise if you want something a little easier get the Timex Q version of this. It comes with a battery powered quartz movement, while it ticks a bit loudly, is a little easier to live with if you aren't accustomed to automatic watches. This is a beautiful Retro Inspired watch, I got it while it was on sale for 120 and it's a steal at that price.

Great Re-release
Color: Stainless Steel/Black/Stainless Steel
So, let’s get my bias out of the way. This was a birth year re-release so I had attachment already. The appearance is so timeless yet you get when it comes from. The case is beveled much like a diamond deconstructed. And the plating is to a mirror finish on top but is brushed on the sides. Really classy. The lens is nice and domed, yes it’s acrylic and will probably get beat up, and a protector is out the window because it’s raised but the dome is such a character in the vibe of this watch. The metal strap is unique both in design and thinness. Now there are some negative reviews on this clasp. It can be finicky, but there is a right and wrong way. Really make sure the two hook tabs are firmly seated on the bar before closing. If the clasp is tappy after clicking it, it is most likely clicked above where it needs to be. Re-seat the hooks and make sure when it clicks in, if you tap the top there is zero rattle. I also suspect people are having issues not properly seating the adjust tab when changing length. You must make sure it is seating between links or it will open on ya… Accuracy wise, and power bank wise it falls shorter than what I am used to. If I don’t wear it after a full day of use and some manual winds even, it only lasts a day - still testing, because I swap out to a Seiko and a Citizen. Nice clicky one way bezel. Lume is pretty 70’s… But this watch is stellar. Timeless yet retro, classy but casual Tee and Jeans worthy. Definite score.
