Astrophytum Myriostigma Fukuryu Description: Astrophytum myriostigma cv. Hakujo Fukuryu is the result of crossbreeding between two of the most famous Japanes myriostigma cultivars Astrophytum myriostigma cv. Hakujo and Astrophytum myriostigma cv. Fukuryu (type B) nudum and shows some interesting intermediate features of both the parents. These hybrids have inherited by ‘cv. Hakujo’ the felty line between contiguous areoles so it seems like the areoles are connected with each other and by ‘cv. Fukuryu’ the many irregular (more or less prominent) “warts” between and on the ribs surface that cuts the continuity of the ribs and the plants appears decorated with a design which is raised above the surface. The plants are very variable and several clones are available.
Stem: Pentagonal to almost spherical.
Ribs: Usually 5.
Flowers: Like those of the well known A. myriostigma, pale-yellow, shining-silk.
Blooming season: Spring to summer.
Cultivation and Propagation: Astrophytum myriostigma is a summer grower species relatively easy to grow. It is sometime seen as a grafted plant but grows very well on its own roots too.
Growth rate: It is a slow growing and easily flowering species.
Soil: Use mineral well permeable substratum with little organic matter (peat, humus), plants may become too elongated if compost is too rich.
Repotting: Re-pot every 2 years. Use pot with good drainage.
Fertilization: It grows much faster with a low nitrogen content fertilizer in spring and summer. Potassium helps maintaining the plants compact and healthy.
Watering: Requires careful watering to keep plant compact. Water sparingly from March till October, the thin, fibrous roots suffer if there is humidity, therefore the plant should be watered only when the surrounding terrain is dry. Keep dry as soon as the temperature starts dropping in October and keep it perfectly dry in winter at temperatures from 5 to 15 degrees centigrade.
