Deadly Blossom

Choose a large area (10' by 10') on the ground within range that is not occupy by huge or bigger creatures (can be occupied by large or smaller creatures though). A large carnivorous plant appears in the space. Each creature within the zone must suceed a dexterity saving throw or be grabbed inside a large carnivorous plant. On the round you cast the spell and at the start of every of your subsequent turns, creatures inside the plant receives 2d6 bludgeonning damage + 2d6 poison damage. They recieve half damage on a successful save and aren't grabbed by the carnivorous plant. Creatures that want to free themselves from the deadly flower can try a strength (athletics) roll against a your spellcasting difficulty + 2. In addition to the deadly flower at the center of the area, lashing vines strikes any creatures within a reach of 15' from the flower (so a sphere of 25' radius from the spell center, including creatures that are burrowed underground). Each creature starting their turn within the area must succeed at a dexterity saving throw or receive 1d6 bludgeonning + 1d6 poison damage, or half as much on a successful save. The total area of the spell is considered difficult terrain. This spell can't be cast on metallic flooring or in a zone that can't fit the whole spell area, including the vines.

When cast at higher level, the poison damage of the flower and from the vines upgrades by 1d6 for each spell slot level higher than 4th and the DC to escape the grasp of the flower increase by one per each spell slot level higher than 4th. When cast with a 9th level spell slot, the flower at the center is now huge (15' by 15", total zone of effect is a sphere of 30' radius with the vines) and can be cast under huge or smaller creatures.
