I mean, realistically, there's nothing that stops you from treating a dead tulip as a plant creature for the sake of the spell. The only reason basic plants are not considered creatures is so you don't have that guy asking how much damage he did to the bladed grass swarms that the party is standing on.
From a real life botanical perspective, plants are extremely resilient, and even if a plant looks completely dead, its roots or other smaller structures could still be alive and functioning, and if that's the case, all you need is the plant growth spell to make the living parts regrow back through the existing dead parts. Maybe tend those parts away first tho.
The big question is: do plants have souls? Because raise dead, and similar spells, interact with that soul to bring the creature back to life.
To answer the question about whether or not plants have souls: Do they have Wisdom and Charisma scores? No? Then, no.
I would look at the problem along these lines: Treat a 'dead' plant like an object, but instead of repairing it, you have to heal it. I'd allow a player to use positive energy to 'repair' the plant and then a spell that encourages growth (or the like) to return actual life to the plant(s).
When is a strawberry [or any plant] dead?
Instant fertilizer or the harvest season spell might bring seemingly dead plants to life.
If you've got a definitely dead piece of wood or similar and you want to recreate a tree that's harder. Use it to make a feather token (tree) perhaps. Anything else I can think of has a temporary duration.
I think non-creature plants are objects. A dead plant would be a broken or destroyed one and you would repair it with the appropriate spells. Mending, make whole, hammer of mending, and so on.
It's a bit wonky, I'm not sure how I feel about using fabricate to make trees from lumber, but we're stuck with "creature or object" being the only existence types.
For those interested:
This type comprises vegetable creatures. Note that regular plants, such as one finds growing in gardens and fields, lack Wisdom and Charisma scores and are not creatures, but objects, even though they are alive.
Here we have objects that are specifically 'alive'.
I added a "tree of life" to my Kingmaker campaign... this massive tree was growing at the intersection of two Ley Lines, its taproot tapping into the channels of vast energy below...
A construct had been sent to cut down the tree, and stand guard over its remains. The party killed the construct, but didn't know what to do with the now petrified tree of life.
The party employed the help of a local witch.. I made Old Bedlame into a real Witch, unstead of a Sorceress that locals happened to call a witch. I made her a Ley Guardian, because reasons.
Anyways, I had her fly above the pertrified stump, cast Disintegrate (twice) to blast a hole down to ground level... then she did some more "Witch stuff" to make a fresh little sapling sprout from within the hole she blasted.
Disintegrate isn't on the Witch spell list, but nobody seemed to care.
"Witch stuff" is in no way an official Paizo term, and honestly does very little to explain what she did, at all.
But the party was happy with the outcome... their efforts paid off, and the show conitued without a hitch.
