Malaysian Monarch is my favorite Munson purple, and I've grown it for at least 20 years. It's a strong grower yet a moderate increaser, with nicely branched scapes. What makes it stand out is the fact that it's very well-mannered, with flat, wide-open segments which open consistently well even when the weather is uneven.
The substance is not exceptionally thick and heavy, but for some reason, Malaysian Monarch is more sunfast than most other flowers in its class. It has never shown much rust either.
I've shared many divisions of this one.
