Update: It's a three-way tie for first as Purple and White (!) Rose in the west catch up to White Cosmo in the east
On the west: Purple Rose ties up with White Cosmo, as does surprise re-entrant White Rose. Meanwhile, Pink Rose adds two flowers and Red Rose one as they prepare to make challenges of their own.
On the East: having extended themselves to take the race lead, White Cosmo widens their base. Meanwhile, Orange Windflower adds two but remains two flower-lengths behind White Cosmo
