Where to buy Roridula in US?

[zhilin]

After have seen beautiful photos here, I am going to grow Roridula. But I find all the CP stores I know don't sell this type of plants. Can anyone tell me where can I buy it? or sell me your extra plants?

Thanks,
Zhilin

Due to the very sensitive root system of these plants, and rarity, you will most likely have to start from seed.
