Cactus / heterochromus

 A thelocactus heterochromus was in flower yesterday.

Since the species was very popular, I bought 10 seeds and sowed in 2006.

6 plants have survived. The cactus on the photo is 12 cm in diameter.

I bought seeds and sowed in 2004. 4 plants have survived.

 A strombocactus disciformis was in flower yesterday afternoon.

I sowed seeds in Nov. 2018. It is the largest one among seedlings, which is 3 cm in diameter.

It is the 1st flowering of the cactus.

Cactus / myriostigma

 An old astrophytum myriostigma was in flower in the afternoon.

I propagated the cactus from seed by myself.

The cactus is 17 cm in diameter and 22 cm tall.

Cactus / astrophytum hybrid

 The photo is a 1st filial astrophytum hybrid, coahuilense x super kabuto.

Flowers of these 2 pecies are very similar and so you can make a hybrid easily.

The cactus is 15 cm in diameter.

 The photo is a 1st filial hybrid, Turbinicarpus alonsoi x Strombocactus disciformis which were in flower in this morning.

Tubercles of the cactus are shorter than that of standard alonsoi.

The cactus is quite small, 45 mm in diameter.
