Would MO Botanical Garden still carry Kalamonding seedlings. In 1986 I was able to buy these Asian citrus seedlings called Kalamonding.

Calamondin trees are available online as seeds up to mature trees, yes even on Amazon.. I was at MOBOT gift shop recently and did not see any citrus trees.

I wish I could help. But I have no knowledge of what they sell.

I'm not sure. You would have to call them to see what seedlings they have available. Their gift shop rotates and changes constantly.
