Sedum Sexangulare Summary

Sedum Sexangulare Physical Characteristics

This plant is also known as the six-angled stonecrop due to the arrangement of its leaves. Its leaves are arranged in spirals in six rows. They are dark green and beautiful. Some observers have confused this plant with Sedum Acre, but Sexangulare has longer, thinner leaves. Also, its leaves are less acidic when tasted, thus the name Tasteless Stonecrop. It has a mat, forming habit rising to about 5 to 15 cm but with a 50 cm spread.

Its roots are perennial and fibrous whole. It has a thick, short stem that branches at the base. Its leaves are small and sausage-shaped, have an average length of 3 – 7 mm and a thickness of about 1.5mm, and are densely packed.

It produces a branched inflorescence from which five-pointed starry flowers grow. They are Hermaphrodite and have pale yellow petals.

Sedum Sexangulare Care

This plant requires little water. It is susceptible to rotting when overwatered. Allow water from the previous drink to dry out before giving the plant another drink during the growing season. Avoid watering in winter altogether or give very little water if you notice water distress.

It does well under full sun but can survive under light shade. Consider providing shade when it is too hot because its leaves can get scorched. Also, the plant is only frost tolerance up to -12oC. It needs to be moved indoors if the temperatures go below that level.

It prefers poor, well-drained soil. Therefore, when preparing the substrate, ensure it has a more significant percentage of gravel than organic matter or loamy soil.

Sedum Sexangulare doesn’t need fertilizer to grow. However, you can enhance growth by adding a half-strength cactus fertilizer once annually after the first year in the same substrate.

Sedum Sexangulare Growth

You can grow it as an ornamental plant on a stone wall like a drape. Also, you can grow it in rock crevices and as a cover plant. Propagation is best done with stem cuttings, which should be relatively easy because it has branched stems.

You can prune the plant for better circulation since the dense leaves can form a suitable habitat for pests. Mealybugs, scale insects, and aphids are among the most common pests. Keep them at bay by keeping the plant healthy and using systemic organic pesticides. Repot when the plant outgrows its pot.
