Astrophytum Myriostigma var.Nudum
Astrophytum 'Myriostigma Nudum'
Astrophytum myriostigma var. nudum (nude form also known as 'Hekiran” in Japanese speech) is very similar to the other myriostigma, it only deviate from the well-known typical form for lacking or mostly lacking white flecks, giving a bright green, blue-green, gray-green or mauve-green color overall depending on clones. It is by some considered an extreme form of the subspecies potosinus. Stem: Spherical to shortly columnar with age. The stems is smooth and can be over 120 cm tall and 5-10 cm in diameter and are shaped like a bishop's headpiece or a star. Spines: None. Ribs: The number of ribs vary from 3 to 8 (usually 5). Flowers: 5 cm in length, pale-yellow, silk-shining unlike the white-spotted plant, occasionally with an orange gloom. Blooming season: Spring or early summer, They take up to 6 years to bloom. Fruits: Dry, dehisces towards the apex forming about 5 star shaped lobes. With few seeds. New:Astrophytum is a genus of six species of cacti sometimes referred to as living rocks. They are quite popular amongst domestic cacti collectors for their flowering habit; their flowers are usually yellow or white. Some species will become short columnar later in life if properly maintained. Some also have distinctive white flecks on their bodies. They are readily propagated from seed.

Planting young plants
From Early Summer TO Late Summer
Astrophytum typically don't like direct afternoon sunlight and should be in partial shade through the hottest hours. They can take direct sunlight in the morning and afternoons. A rich, fast-draining cactus mix is ideal. To plant, do this preferably during the warm season. To repot a cacti, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
Propagation
From Late Spring TO Late Spring
Astrophytum are propagated from seed. Use John Innes No 1 with added grit or sand for added drainage. Sow the seed in spring. Large seed will need a covering of one to two times the depth of the size of the seed. Small fine seed should not be covered, but mix the seed with a little sand to help with an even distribution. Water with a misting bottle or a watering can with a fine rose and cover the pot with a sheet of glass or plastic bag. Keeping them at 21°C in partial shade. Allow air into the pot daily by removing glass or plastic bag and wiping off condensation. Keep moist but not overly wet. Pot on seedlings when they are big enough to handle. It can take up to 12 months for them to reach this stage.
