They are both very nice plants the two you ordered. I have both and I particularly my Racha phunlan.

I am not completely sure if one is considered a TS arabicum or just an Arabicum hybrid. A TS is not considered a TS unless it hold the characteristics required. Seed grown TS are not necessarily going to give the results either.

As for fast growing. This will depend on where you live and conditions given. With optimal conditions or living in Thailand, they probably grown alot faster.

My Thong Tonnam is definitely a quicker grower in comparison to some of my others.

I'm in south central texas. Hot sub tropics. They seem to grow fast here, at least mine are after I figured out the right culture for them. When ita hot they want water and fertilizer that would kill most other succulent plants. Initially I was growing them like like a jade plant or echeveria.

Todd, please show us some pictures when they come.

I hope they bloom well for you.

Sure they should depart Thailand today so a week or so I hope to get them here in Texas. Soon I'll have my own source of seeds. I'm having fun with my seedlings they grow really quickly and show a lot of variation.

The one thing with the Arabicums is not to push too hard with Nitrogen. Will make them put on too much branch growth and can become unbalanced.
