A lot of interesting mechanics thrown in here, but I can't see myself excited to play her. It's not just a lack of damage; outside of her ultimate, there is no way for her to directly impact or interact with enemies. She is going to have a super hard time in lane against many other supports, especially aggressive CC heavy ones like Leona or Annie - the stats that she can grant are pointless if your carry is stunned out. And at the end of the day, no one wants to play a buff-bot. Sona has the same type of approach, but she has tools that make her more exciting and interactive in lane. Her Q allows her to bully out enemy laners and gain an early upper hand in lane to compensate for her lack of pre-6 CC. And few things are more thrilling than catching the entire enemy time in a surprise flash-Crescendo engage.

Aside from that, you should lower the threshold for her some of her scalings - haver her gain smaller bonuses at lower AP counts. She's not likely going to have a ton of AP as a support - Janna often gets away with a Mejai's because she has so many defense mechanisms (shield, knock-up, knock back, free movespeed). Julia has none of these. The lower thresholds will make the small increments of AP she picks up feel like they are impactful.

12% HP heal is super high, especially without a real limit or cooldown associated with it (think about stacking a bunch of these under turret for the first 3 minutes of the game). I would consider making a limit for the number of plants, and/or make their durations shorter to make a window where allies need to capitilize on this extra power.

But mostly, she just needs something that can allow to have a bigger splash in lane and get players excited to play her.
