Hello Aeronwy,
With the blood of the evil ones as sacrifice I enacted a glorious rite to Kula where I planted a beautiful thistle tree. Onion and Amelie watched. Amelie asked though that I move the thistle to hunt and weaken the accursed djinn foe so she's now elsewhere. The Rose should guard her as she is strong enough to withstand ash and will eat djinn things.
I can plant regular seeds but they will not withstand the scourge of ash. Only with the blood of the evil ones can I keep a strong garden outside.
I don't know if this enough to grant what I asked. If Rose wants to see the precious thistle, I can guide you there. She will help with the death march.
