You prompt a seed to instantly grow to an ally plant creature.
The Plantbeast is rooted in place, has a challenge rating of 2, and possesses a blunt force lash attack with a range of 20 feet and the Constrict skill. It is immune to blunt force, resistant to piercing, but vulnerable to slashing with low Hitpoints and Constituition.
A summoned creature disappears when it drops to 0 hit points or when the spell ends.
The summoned plantbeast is friendly to you and your companions. Roll initiative for the summoned creature, which has it's own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions.
